Every day at Western States Metal Roofing we are asked the same questions from homeowners just like you that are looking to purchase a metal roof. We love to educate our customers and help them determine which metal roofing panel is best for their home. However, we thought there had to be a better way to get this information to the public and do so without any pressure to purchase.
We looked online to see if there was a guide to corrugated metal roofing. All we found was a jumbled assortment of incomplete information. Nothing existed that had all of the information homeowners would need in one place. Finally, we decided it’s time to write an extensive guide to corrugated metal roofing. This guide will answer all of the questions that you have, and even some that you would have never thought of.
This definitive guide will teach you about every aspect of corrugated metal roofing. You’ll have a very good idea if this is the right roof panel for your home, or if you should consider other panels. If corrugated metal roofing sounds like it could be an option for your home, you’re in the right place.
You have lots of questions about corrugated metal roofing. Instead of going through several different articles, we’ve created a comprehensive guide with all the answers in one spot.
To start at the beginning, corrugated metal roofing is an exposed fastener panel. This means that the screws will penetrate the roof panel when attaching to the plywood or metal substrate of your home. A substrate is the surface upon which the metal roofing or roofing underlayment is applied.
Visually, the appearance of a corrugated metal roof panel is wavy with “S” shaped curves. The term “corrugated metal panel” would not include a panel that is square or has a boxy appearance. In addition, the term typically refers to the two most common types of corrugated metal roofing: ⅞” Corrugated and ½” Corrugated.

Here’s the funny thing about corrugated metal roofing though: If you were to ask two people to describe it, you may get two completely different answers. It’s one of those terms that has been around for hundreds of years and the meaning has changed as the product evolved.
The old school definition of a corrugated metal roof is any metal roofing panel that is not a standing seam panel. This could mean anything including wavy corrugated, R Panel or 7.2 Panel.
We will be referring to standing seam a lot in this article so we should define it. Standing seam is a concealed fastener metal panel system that has vertical legs with flat area located between the two legs.
Although there is a difference of opinion of what the term “corrugated metal roofing“ means, there are some common characteristics that embody both the modern and traditional definition of the term.
Corrugated metal roofing starts as a large round coil of steel. The coil is put on a machine that will roll-form the corrugated roofing sheets. The metal starts as a flat piece of steel and then it passes through a series of rolling dies. Each of these rollers bends the steel until it comes out the end of the machine as a piece of corrugated metal.
The length of corrugated roof panels can vary depending on where you are sourcing material. There are two ways to purchase roofing:
For more information on how to purchase corrugated metal, head to Chapter 7.
Corrugated metal roofing typically refers to round and wavy sheet metal. However, it can also be used as a catch-all term for any type of exposed fastener panel. For an in-depth comparison of the types of exposed fastener panels, head to Chapter 4.
The different types of corrugated metal roofing panels are:
⅞” Corrugated in Zinc Metallic
⅞” corrugated metal roofing is the most common wavy corrugated roofing panel. It’s name originates from the rib height of the panel which is ⅞” inch. The deep round corrugations make a great looking panel that is also durable. In addition, this panel is wider and costs less than ½” Corrugated metal roofing.
Why you would prefer a ⅞” Corrugated metal roof:
½” Corrugated Metal Roofing Panel in Weathering Steel
½” Corrugated is the classic and old school metal roofing panel. Nowadays, you see it used less often on construction projects. Some of the reasons we don’t recommend using this panel are:
Here is when you should use ½” Corrugated:
These panels that fit in this category are more of the traditional definition of a corrugated metal roofing panel. From a manufacturer's perspective, we would not call a square or boxy panel a corrugated panel. However, the product has been around for so long that it’s kind of a catch-all name for metal roofing.
Any panel that is an exposed fastener panel could technically be referred to as corrugated metal. Any standing seam panel would not be considered corrugated metal. There are many types of ribbed metal panels, but the most common are R-Panel or PBR Panel.
Corrugated metal is a great fit for a lot of different homes.
Before we get into when to use corrugated roofing, let’s talk about why you’d want to use corrugated metal in the first place. This type of roofing has a lot of valuable benefits. After that, you’ll learn when a corrugated metal roof would be a great option for you, and when it may not be.
⅞” Corrugated Metal Roof in Bonderized
One of the biggest benefits of corrugated metal is that it’s one of the most affordable types of metal roofing. This makes it the perfect material when the cost is a primary concern.
You can expect your total cost including material and installation to be in the range of $5.00 to $8.00 per square foot.
There is not much to worry about in terms of maintenance besides inspections, basic cleaning, and checking the fasteners.
You’ll need to have regular inspections and also a quick inspection after any major storm to make sure the roof doesn’t have any problems forming such as leaks that can lead to water damage. Inspections are recommended to prevent minor issues from becoming major issues.
You’ll also want to clean off any dirt, debris, or leaves to keep the roof from being scratched and the gutters from getting clogged. Clogged gutters prevent proper drainage during rainstorms, which can ultimately damage your metal roofing system.
Corrugated metal roofing will have thousands of screw penetrations. Because of weather changes, your roof expands, and contracts. As a result, over the course of many years, these screws might back themselves out. Sealing washers can also deteriorate after many years. It's recommended that you inspect the fasteners every couple of years so that it prevents leaking.
Metal does not rot or support any microorganisms such as mold or mildew unlike asphalt shingles. It also isn’t susceptible to termite or rodent infestation. Damage caused by all these factors are both inconvenient and expensive. Having a metal roof eliminates any worries of having to deal with those issues that are both expensive to fix and could cause health issues.
Another big advantage to metal is that it’s one of the few fire-resistant roofing materials. It has the best fire rating available, making it ideal for areas that are prone to wildfires. A fire-resistant roof protects your home and your family from the danger of a fire.
A metal roof can last an average of 50 years, and longer in many instances.
The initial upfront cost of a corrugated metal roof will be slightly higher than a material like asphalt shingles. But metal roofing also lasts for 2-4 times longer than alternatives like asphalt shingles.
In the long run, you are getting a greater value with metal.
Metal roofing can be designed to sustain wind gusts up to 140 miles per hour. The product durability makes it an excellent roofing choice in areas that are affected by hurricanes or other extreme weather conditions. Metal roofs are designed to not crack, chip, or warp.
Metal is one of the most energy-efficient roofing materials. Besides being made of 100% recyclable material, it also helps homeowners reduce monthly energy bills by reflecting solar radiation back into the atmosphere.
A metal roof can result in homeowners having a general energy savings of 7% up to 15%. One study funded by the U.S. Department of Energy showed an annual savings of 25% on cooling costs.
Metal offers the most variety of design choices for roofing. Besides having different profiles to choose from, corrugated metal roofing panels come in a wide range of different colors and finishes.
More color options gives you more flexibility to create the home of your dreams. Homeowners aren't limited to a few boring options, but can truly make their roof, and as a byproduct their home, unique and special.
There are hundreds of corrugated metal roofing colors to choose from.

As we mentioned earlier, corrugated panels are affordable when compared to standing seam metal roofing. This makes them a great roofing solution when you want a metal roof, but are working on a smaller budget.
If you’re really looking to cut down costs, you can save on your installation cost by taking the DIY route. The process of installing corrugated metal is simpler and faster than other types of metal roofing like standing seam.
If you’re up for the task, read more on how to install corrugated metal roofing.
Oil canning is a cosmetic deformation, observed as waves. There is no way to prevent oil canning because it’s inherent to the product itself. Oil canning doesn’t affect the functionality of the roof, but can give off an undesired, wrinkled appearance.
The shape of corrugated panels helps hide oil canning to make it less noticeable. Since corrugated panels don’t have any flat areas, oil canning is harder to see as the design of the panels is already wavy. Oil canning is most prevalent on standing seam panels.
While corrugated is now popular in the residential market, its original purpose was to be used on barns and industrial structures.
The cost-effectiveness along with being a material that is quick and easy to install makes it a convenient roofing panel that’s used in agricultural and commercial settings. In these types of situations, time and money are generally more important factors than appearance.
Corrugated panels are the most readily available type of panel.
If you’re in a situation where you need materials fast, corrugated roofing panels are available for purchase at most home improvement stores.
A metal roofing manufacturer can provide a wider selection of colors and custom panel lengths, however, there can be a wait time of up to two weeks to receive your shipment.
⅞” Corrugated Metal Panels in Matte Black
Corrugated metal is a great roofing solution in many cases, but it’s not for everyone. Let’s go over when you should consider choosing a different type of roof.
While metal roofing is low maintenance, corrugated is a type of metal roofing that requires a little more attention because of the exposed fasteners. Because the screws that keep the panels in place penetrate the roofing panels and are visible.
As we mentioned above, screw penetrations are the main disadvantage of a corrugated metal roof. Since they’re exposed, the fasteners can become loose over time. Loose fasteners can lead to leaks as it creates room for water to penetrate between the screw and sealing washer.
The fasteners need to be checked and possibly tightened during inspection to prevent leaks.
If you aren’t comfortable with the idea of regular inspections, you may want to reconsider using a corrugated roofing panel. Standing seam might be a better fit.
As the weather goes from hot to cold and vice versa the sheets will expand and contract. However, corrugated panels are pinned in place by the screws. The movement of the panels over many years can cause the screws to back out a bit. This means periodically, you will have to go up there and re-tighten or replace them. This is less of a problem with shorter sheets versus longer sheets.
A screw has a sealing washer that is designed to keep the water from leaking between the screw and the panel. However, there are thousands of them on your roof. Any screw that is installed at an angle, over-tightened, or under-tightened is a potential leak point.
The washers on your screws are not designed to last as long as the roof itself. After many years they will break down and the screws will need to be replaced with larger ones.
When you purchase a metal roof, the most important decision is to determine whether an exposed fastener panel or a standing seam panel is best for you. We highly recommend that you read this article as it covers this subject in much more depth.
Metal is a very durable material that can handle harsh weather, but there are two components of corrugated panels that can be an issue:
Climates that often have weather conditions such as high winds, hail, and heavy rain, need a roof with a heavy gauge steel. Corrugated can still be appropriate in these elements, but you don’t want the lighter gauge panels that you find at Home Depot. You want panels with a heavier gauge, such as a 22, 24, or 26 gauge, that will provide extra protection from weather damage.
You’ve seen us bring up the point about how exposed fasteners can create opportunities for leaks to occur. We want to stress how important it is to consider the amount of fastener penetrations and how they leave the roof vulnerable to leaks and water damage. The more precipitation your climate has, the greater the chances are of a leak occurring.

As we mentioned earlier, corrugated panels have an informal look that can complement your home in the right environment. However, its waviness may not look modern or contemporary.
If you’re looking for a modern design, it would be better to go with a metal panel like standing seam. These panels have a flat appearance that’s more modern looking.
Corrugated metal brings a lot of value to your roof when used in the right situation.
There are a ton of benefits to corrugated metal roofs, and metal roofs in general. But in order to make the right decision for your home, you need to know your other roofing options.
Let’s compare corrugated metal to different roofing alternatives.
There are more panel options for your roof besides corrugated metal. As we’ve mentioned several times now, the most popular alternative metal panel to corrugated is standing seam. Outside of metal roofing, the two most popular roofing panels are asphalt shingles and clay tiles.
It’s important to consider the style and performance differences when comparing these panel types.
We’re going to highlight the advantages of each of these alternate types of roofing options.
Here at WSMR we specialize in metal roofs and manufacture both corrugated and standing seam panels. However, we realize you have other choices for roofing.
Asphalt shingles and clay tiles are two other common types of roofing. While we are not experts in those roofing materials, we do want to discuss them. We want to make sure you’re aware of the other options you may come across while searching for the perfect roof.
A standing seam roof features panels consisting of a formed metal sheet with vertical ribs at the panel edges, installed by lapping and interlocking edges of adjacent panels. The panels are attached to substrates using concealed clips and fasteners. We understand that sounds like a lot of confusing roofing talk. Simply said, the panel is smooth and does not have any fasteners showing.
Standing seam roofs bring homeowners the combined advantage of performance and appearance over corrugated. That’s what you are paying for when you purchase a standing seam metal roof. It’s the most modern-looking panel, it’s the longest lasting, and it’s the least likely to leak.
While both corrugated and standing seam are exceptional products with similarities, there are a few key differences.
Standing Seam roof in Copper Penny®
This type of roofing system has fasteners that are not exposed. Since they are not exposed to the weather there is not an opportunity for the fasteners to leak.
A corrugated roof has an exposed fastener metal roofing system where the screw heads are left visible, or “exposed”. Corrugated metal panels are fastened directly onto the roof deck with screws that penetrate the panels.
When you have a concealed fastener system you don’t have to worry about the fasteners loosening or backing themselves out. You won’t have to routinely inspect and re-tighten the fasteners.
The look that is desired for your roof is a personal preference. However, the clean lines and modern look make it widely considered to be the most attractive metal roofing option. Standing seam roofs give off a more streamlined look than a corrugated metal roof.
Roof slope refers to how steep your roof is. Roofs can be categorized based on their slopes.
Slope can be expressed in degrees or as a percentage but is often seen in ratio form, such as 3:12 or 6:12. This number indicates how many inches the slope rises for every 12 inches it runs horizontally. For example, a 6:12 roof pitch means that the roof rises 6” for every 12” moving inward.
Corrugated is best for roofs with a slope of 3:12 or greater.
If you have a roof with a lower slope than 3:12, a standing seam roof will be the better option for your home. Mechanically fastened standing seam panels are suitable for roof pitches of 1” in 12” or greater, or 1:12.
The composition of a standing seam roof makes it convenient when installing solar panels. The legs on the panel allow a clamp to easily attach the solar panels to the roofing panels. Drilling into the roof is not required, which allows you to avoid those penetrations that can lead to leaks.
Other rooftop additions, such as snow retention systems, are easily installed in a similar way.
Gauges on standing seam panels are thicker than most corrugated panels. As the gauge number gets lower, the metal gets thicker.
Standing seam panels are usually between 22 and 24-gauge, while corrugated panels are usually 26 or 29-gauge. Corrugated can be made to order in 24 gauge but is rarely found in heavy gauges with immediate availability.
Why does this matter to you?
The added bulkiness heavier gauges more equipped to handle severe weather and less likely to fail when exposed to high winds.

If we give you the good news, we also have to give you the bad news. One of the biggest reasons why people choose not to get a standing seam roof is because of its price tag.
A standing seam will cost $8 to $14 per square foot including materials and installation.
They are the most expensive metal roofing panels, and can cost more than double the price of corrugated. A contributing factor to its higher price is labor cost. The installation of a standing seam roof is more complex than a corrugated roof, and is therefore also more expensive.
If you drive around your neighborhood, you are very likely to see asphalt shingle roofs. This is because asphalt shingles are the most commonly used roofing material.
Its popularity has a lot to do with affordability and ease of installation.
There is a wide range of quality and costs within the asphalt shingle roofing category. The national average cost for architectural asphalt shingles is $6 per square foot. The installation process is relatively quick and can usually be completed in 1-2 days. An asphalt shingle roof takes less time, tools, and skills to install compared to a metal roof.
While the price and quick installation might be appealing, this roofing material also has some drawbacks.
An asphalt shingle roof does not last as long as other types of roofing. Generally, this type of roof can go an average of 10-20 years before needing to be replaced. By comparison, a metal roof can last 40-60+ years.
That doesn’t mean that your asphalt shingle roof will look nice and brand new during it’s 10-20 year lifespan. Shingles have a functional life and an aesthetic life. The functional life of an asphalt shingle roof is about 17 years. That’s way different than the aesthetic life, which is about 5 to 7 years.
The aesthetic life is when the shingles are stained and streaked. The elements have weathered the shingles so that it looks like an old roof. Even though the roof is functioning and performing against the weather, the roof looks like it’s on its last leg. It begins to lessen the home’s curb appeal and property value.
As an asphalt shingle roof ages, repairs will also become more frequent. This type of roofing isn’t known for durability, and high winds can blow the shingles right off. Replacing shingles that are missing, broken, or buckled from age or weather will be necessary.
As we mentioned earlier, this type of roofing is very popular. Whether or not you want your roof to stand out in your neighborhood is a personal preference. Sometimes it might also be a decision that is out of your hands. If you are a part of a Homeowners Association (HOA), you might be required to have a certain style roof.
If you are looking for your roof to be unique, that is a harder task to accomplish with asphalt shingles. In addition to being a commonly used roofing material, the color selection for asphalt shingles is also very limited, especially when compared to metal roofing.
If you are really interested in the comparison between metal roofing and asphalt shingles in terms of return on your investment, we suggest skipping ahead to Chapter 7. We provide a full breakdown of the numbers to see which roof will give you more long term value.
A clay tile roof is a premium roofing material that shares some of the primary benefits of metal roofing.
Clay tile roofs also have their downsides.
One of the biggest drawbacks to clay tiles is that they are fragile and easily break.
Also, unlike metal, these types of roofs are incredibly heavy. These types of roofs are roughly 850 pounds per square foot.
You need to make sure your home can support the roof so that the extra weight doesn’t cause expensive structural damage to your home. If it’s determined that your home won’t be able to support the weight, you’ll have to pay to have additional structural reinforcement done before your home can have a clay tile roof installed.
Additional structural reinforcement alone can be an additional $6,000 to $15,000 expense depending on how much work needs to be done. That expense does not include the material and labor for your actual roof.
A clay tile roof will cost roughly $10 to $12 per square foot. Like with other roofing materials, there is a price difference depending on the quality of the material used. For example, the very popular Terracotta roof tile can be 20 to 30% more expensive than regular clay.
Let’s assume you have now decided against clay tiles and asphalt shingles for your new roof. After reviewing the pros and cons of both types of metal panels, you can make an informed decision about which panel works best for you.
Take factors such as your design preference, budget, roof slope, and climate into consideration when deciding between all of your panel options.
If you’re going with a corrugated panel, or an exposed fastener panel, there are several options within this category to choose from. We will help you learn the different types in the next chapter.
Within the corrugated metal panel type roofing, there are multiple options to choose from. Choosing the correct roofing panel for your home is a balancing act between visual appearance, strength of the panel, and cost.
In this chapter we will briefly touch on the pros and cons for each panel, but we have also included links to comparison articles that cover panel comparisons in great detail. Let’s dive into the most common ones to see what their differences are.
As their names might suggest, the main difference between ⅞” corrugated and ½” corrugated panels is the height of the corrugations: ½” deep versus ⅞” deep. The difference in height may seem minimal, but it changes everything from the panel sidelap, cost, overall appearance of the panel, and the durability of the corrugated sheet metal.
With either of these panels, you will have to purchase additional square footage because of the panel side lap. Panel side lap refers to the overlapping of panels during installation. You overlap the panels to lessen the chances of the panels leaking. On a roofing application you lap the panels two corrugations and on a wall application they get lapped one corrugation.
½” corrugated: The panel is 26” wide, but must be lapped back two corrugations for weather tightness. Because of this, each panel will only yield 21.33” of roofing coverage in roofing applications. This means that you will have to purchase about 24% of additional material due to the panel sidelap.
⅞” corrugated: The panel is 39” wide, but must be lapped back two corrugations for weather tightness. Because of the side lap, each panel will only yield 34.67” of roofing coverage in roofing applications. This means that you will have to purchase about 10% of additional material due to the panel sidelap.
Simply because of the panel sidelap, you will need to purchase 14% less material by choosing ⅞” corrugated instead of ½” corrugated metal roofing.
⅞” Corrugated in Medium Bronze
⅞” corrugated costs significantly less when compared to ½” corrugated metal roofing.
⅞” corrugated will save you around 10% to 15% when compared to ½” corrugated. Keep in mind that going with the ½” corrugated route requires you to purchase 14% more material due to the panel sidelap.
When combining the panel cost and panel side lap, the total savings when using ⅞” corrugated versus ½” corrugated is a whopping 25%-30%.
⅞” Corrugated in Streaked Blackened Rust®
The general rule is that as the height of the panel increases, so does the strength of the panel. The depth of ⅞” corrugated is ⅜” of an inch deeper than ½” corrugated. That’s a 38% difference in the height of the panel.
Since ⅞” corrugated has deeper corrugations, it’s a stronger and more durable panel compared to ½” corrugated.
The method of installation is the same for both panel types. However, ⅞” corrugated is a much wider panel profile, so there will be less sheets to install.
Each sheet of ½” corrugated (after the overlap) will cover your roof 21”. While each sheet of ⅞” corrugated (after the overlap) will cover your roof 34.67”. The ⅞” corrugated provides 65% more coverage. This means that you will have to less sheeting to purchase and install when using ⅞” corrugated metal roofing panel. This will save you time and labor costs.
⅞” Corrugated in Matte Dark Bronze
You Should Use ⅞” Corrugated When:
You Should Use ½” Corrugated When:
Even though the corrugation sizes are different, both ⅞” corrugated and ½” corrugated have a similar wavy appearance. If you want a roof with a boxy appearance, consider R-Panel.
Corrugated and R-Panel are metal panels that were both originally designed to be a readily available, low-cost option for agricultural applications. Over time, their uses have become more versatile. It’s not uncommon to see both panels used in residential and commercial projects as roofing and siding.
R Panel is the cost common type of metal roofing that’s not a wavy panel or standing seam. ⅞” Corrugated is the most common wavy corrugated panel. Since these are the two most common exposed fastener roofing panels it makes the most sense to compare their differences.
“Corrugated” refers to any type of metal that is formed into grooves or ridges. However, corrugated metal roofing panels are traditionally round and wavy while R-Panel is boxy. R-Panel is generally considered to be a more modern look than corrugated. The appearance of R-Panel is sometimes compared to standing seam.
As mentioned earlier, the strength of a panel is determined by the height of the panel and the corrugations of the panel. This can become a very technical question concerning stress, deflection, number of spans, and gauge. To keep things simple, both 7/8” corrugated metal panels and R-panel are similar in strength.
Both R-Panel and corrugated are used in residential and commercial environments as roofing and siding. However, each panel has a more common way of being used.
Corrugated metal panels are utilized for both roofing and siding. They are seen more often in residential applications versus commercial applications.
⅞” Corrugated in Streaked Rust®
R-Panels are used in both roofing and siding applications. However, it’s more common to see it used as siding. In fact, it is the most popular metal siding panel. R-Panel is generally more popular in commercial projects versus residential homes.
Both panels are considered to be affordable metal panels. However, R-Panels generally cost about 10% to 15% less than corrugated panels.
Less material needs to be purchased with R-Panel because of panel sidelap, which we will discuss in the next section.
When you combine the lower price and less required material, R-panel ends up being 20% to 25% less than corrugated metal on a roofing application, and 15% to 20% less on a siding application.
When it comes to ordering material, you will have to buy more corrugated panels than R-Panels for the same roof because of how each panel is installed.
R-Panels are 36” and provide a full 36” of coverage, there is no panel sidelap like with ½” or ⅞” corrugated panels. With R-panels, you pay for what you get. However, corrugated panels will incur that loss of square footage due to the panel sidelap.
You will need to overlap the panels two corrugations for roofing and one corrugation for siding. While this seems minor, it can add up depending on the size of the project.
For roofing, you will have to purchase 10% to 12% additional corrugated.
For siding, you will need about 6% additional corrugated material.
Because of the similar panel strength and availability of each of these roofing types, there are the two main factors to consider:
If you want a round and wavy looking panel, then corrugated metal is the only choice. However, if you want something that is square or boxy, then you will have lots of choices including R-Panel.
If you are on a budget with saving money as your top priority, R-Panel would be the better choice as it is 10%-20% less than corrugated.
They are both great products at a good price point. You’ll have to decide which panel has the look and panel features that matches best with your project.
When contemplating corrugated panels, also take into consideration that corrugated comes in different profile sizes.
A 7.2 Panel or Western Rib is another kind of ribbed panel with a boxy appearance. These panels feature symmetrical ribs that are spaced 7.2” on center, with each rib measuring 1.5” high.
As we mentioned earlier, the deeper a panel is, the stronger it is.
7.2 panel is 1.5” inches deep which is considerably deeper than the other corrugated options such as ⅞” or ½” corrugated. This means 7.2 is also a much stronger panel.
While these both are in the same price range, you will spend less by using 7.2 Panel because you will have to order less material due to panel sidelap.
Similar to R-Panel, 7.2 Panels are 36” and provide a full 36” of coverage. You do not incur the square footage loss that you do from panel sidelap with corrugated panels.
When using corrugated panels for roofing, you will have to purchase 10% to 12% additional corrugated.
When using corrugated panels for siding, you will need about 6% additional corrugated material.
Similar to R-Panel, the choice between corrugated and 7.2 Panel comes down to cost, preference in design, and panel strength.
Factors To Consider:
7.2 Panel is more often used in fencing and siding, but that doesn’t mean that it can’t be used as roofing. It just comes down to which look you prefer and what panel strength you need.
If you like making decisions, then you’re going to love this chapter!
Choosing a metal roof involves making a lot of choices, more than just whether or not you’re going to use corrugated metal roofing panels. By the end of this chapter, you’ll have everything you need to know to pick out the right panel for your new roof.
To help keep you from feeling overwhelmed, we’ve broken up each decision into sections:
The paint system is probably a factor you haven’t really considered. As long as the roof is the color you want, what difference does the paint system make?
We understand why this factor can be overlooked, but the truth is the paint system plays a part in the performance and appearance of your roof. You want to make sure you choose a color in the paint system that will leave you satisfied with your roof for years to come.
The two main paint systems you’ll find are PVDF and Silicone Modified Polyester aka SMP. PVDF, which stands for 'polyvinylidene fluoride', is considered to be the more premium of the two systems. However, that doesn’t mean you should disqualify using SMP panels.
Let’s talk about how the two types of paint systems compare in these areas:
But we won’t just leave you with information on the differences among the two. We will also clearly lay out what situations would make each of these paint systems right for you.
Chemistry may not have been your favorite subject in school, but we have to quickly go over chemical structure to explain the differences in product performance. How well each product performs is directly associated with the quality of its components.
SMP systems consist of polyester and silicone intermediates. Silicone aids in improving the gloss retention and weather resistance of the paint coatings. The amount of silicone in the coating varies depending on the product.
There is a wide range in quality when it comes to SMP paint. You want to look for a SMP with the greater amount of silicone. The higher the silica content, the better the performance of the paint.
PVDF coatings consist of one of the strongest bonds known, called the carbon-fluorine bond. This chemical structure gives it the ability to resist strong acids, solvents and reducing agents.
When it comes down to it, you want the roofing panel that is going to do the job it’s supposed to do and look the way it’s supposed to look. That’s what we mean by performance.
There are two big factors that come into play with metal roofing that impact the appearance of panels:
Both of these issues result directly from the chemical breakdown of a coating’s base resins and pigments. These are two unavoidable components of a painted metal panel that keeps it from looking fresh and new, yet the paint systems handle them slightly differently.
While the silicone in SMP paint helps with resistance to fading and chalking, the exposure to UV rays will cause colors to fade overtime. You will notice some vibrant colors, such as red, tend to fade faster than others.
As for chalking, choosing a lighter colored panel will make the appearance of chalking less apparent.
A benefit of SMP paint is that its resins are harder than those of PVDF. This adds a level of abrasion and scratch resistance to SMP paint.
The strong chemical foundation of PVDF paint makes it more suitable to provide long-term durability. It is less susceptible to losing its vibrancy from UV rays and having its color fade.
A downside with PVDF is that since it's softer than SMP, it can be scratched easier from branches or other debris.
Warranties vary greatly in the metal roofing industry, and they are not always what they seem to be. Make sure you read the fine print and pay attention to what the warranty covers beyond just the length of the warranty.
Paint warranties for metal panels cover 3 areas:
Upon closer inspection of panel warranties, you’ll notice that not all of these areas are covered for an equal amount of time.
At first glance, it will look like SMP panels have a longer warranty than PVDF panels.
You’ll see many SMP painted panels come with a 40-year warranty. While that sounds great at first, you’ll then notice that the 40-years only covers film adhesion.
The coverage for fade/color change and chalk varies for SMP painted panels. However, it is usually always covered for less time than a PVDF panel warranty.
PVDF warranties for color change will vary on the time given depending on which color you choose.
In terms of the other warranties, you can expect to see a range of:
The biggest advantage of SMP paint systems over PVDF is the price. Cost is a bit tricky because sometimes your panel options limit your color options. For instance, if you want a 26 gauge panel then a PVDF paint finish isn’t an option. If you’re considering a 26 gauge panel you must compare a 26 gauge SMP versus a 24 gauge PVDF, which makes SMP substantially less.
So if you’re able to compare the cost of each paint system for the same type of roof, the cost difference could be minimal. For example, the difference between a 24 gauge SMP and 24 gauge PVDF is minimal. But when you consider the cost of a heavier gauge panel paired with a more expensive paint system can cost you between 10% to 35% more than SMP.
We can only provide different aspects to consider as you determine which panel type is best for your situation.

Picking the correct paint system is a critical step in purchasing a metal roof. If you would like a deeper dive into the subject we recommend:
This is the part where the decisions get harder. While there are only a few different gauges and paint systems to choose from, there are over a hundred different colors of metal roofing on the market for metal roofing. How do you choose?
While personal preference should definitely be a main consideration in your decision, there are also some factors regarding your home that should be looked at.
Your metal roof color should blend in with the other features of your home. Think of how the roof will look against the color of the rest of your home.
You’ll want to consider how your corrugated metal roof color will look blend with:
Also consider the colors of features that will be closer to the roof including:
You can choose a color that matches these features, or contrasts them for a pop of color.
Color can help highlight or disguise certain features of your roof depending on the look you want.
Lighter color roofs make your roof look taller. If you have a low roof, this could benefit your home by making it seem taller than it actually is.
Darker colors will have the opposite effect and can make a tall roof look less profound. If you have a roof with a very high slope, you may want to choose a darker color to make the roof look less steep.
Are you subject to the rules of a Homeowners Association(HOA)? If so, you first need to make sure that your HOA allows metal roofs.
Make sure they also do not have any color restrictions. If they do, you want to adhere to the list of approved colors while making your color selection. Once you know what color you want, submit a color chip to the HOA for approval.
The color of your roof can also be influenced by the colors of the surrounding nature. Below are some examples of geographical locations and the roofing colors that are often used in the areas.

You also want to look at the style of your home. Each style usually leans towards certain roofing colors such as the examples below.

For more information on choosing a metal roof color, we suggest reading:
We understand that picking a color for your roof can be a hard decision. Utilizing color selection tools will help make your roofing color choice easier.
We will be discussing 5 main selection tools in the chronological order that they should be used:
PVDF Color Card - Standard Colors
The first step is to look at color cards. Color cards group options together based on color or paint finish. For example, if you are looking for a green roof, this is where you’ll be able to see all the shades of green at once.
Here are some examples of color cards grouped together by paint finish:
Photo galleries are where you can see your favorite choices from the color cards being used. Photos from past projects are a great way to see if you like the color in a roofing application.
Photos are generally grouped together by paint color and panel type to make it easier to search for your desired design.
Color visualizers give you a virtual view of how your roof will look with different panels or colors. You can choose a style of home or upload a photograph of your actual building or home. These programs allow you to create a digital mock-up of different versions of your design.
Each visualizer has different features, but often you are able to customize features such as:
Metal color chips are when you can see a sample of the actual color in person. You want to make sure you look at the sample both up close and at a distance as the color will look slightly distant from different views.
Also, be sure to bring your color chip outside to see it in natural daylight, which is the lighting your roof will be viewed in. Compare the color chips at different times of the day as it will look different in the middle of the day than it will at sunset.
Corrugated panel samples give you the best idea of what your roof will look like as you’ll be receiving a real roofing panel in your desired color.
Sometimes these samples have to be made specifically for you. Because they are larger and heavier than the color chips, they take longer to be delivered.
Panel samples are generally available from all manufacturers, but not necessarily in your chosen color. Every manufacturer has different policies as it’s just not practical to provide a specific color in a specific panel type. Check with the manufacturer for sample availability.
At Western States Metal Roofing our policy is:
So far in this chapter, we’ve talked about choosing the right panel for your roof. There is also another part of your roofing system that you have to choose called roofing underlayment.
While underlayment is often overlooked because it isn’t visible once it’s installed, it is very important to the lifespan of your roof.
Roofing underlayment is a water-resistant barrier that serves as an extra layer of protection from the elements. It is installed directly onto the plywood roof deck, underneath all of the other roofing materials.
There are two types of underlayment to consider:
Felt underlayment is made from recycled corrugated paper mixed with sawdust. When compared to synthetic underlayment, felt is more resistant to leaking at staple or nail penetrations. This is because the paper it's made from is mixed with asphalt that increases its water resistance.
You can generally expect felt underlayment to last anywhere from 12 to 20 years.
Felt roofing underlayment is more affordable than synthetic roofing underlayment.
Sharkskin® Ultra Synthetic Underlayment
Synthetic material is made from sheet products made of laminated polypropylene or polyethylene plastic. Its composition helps it have a longer lifespan than felt. It can last anywhere from 25 to 50 years.
Synthetic underlayment products are strong and will not tear and break from screws and nails penetrating it. While felt is more resistant to leaking at staple and nails penetrations, synthetic is the more durable product. It can handle exposure to weather conditions and will not be damaged by rain. If your roofing is not going to be installed right away, using synthetic underlayment will protect the structure during construction from any water damage.
Depending on which type of synthetic underlayment you use, it can be exposed anywhere from 2 to 30 months and still remain watertight.
It’s also a safer product to work with. Synthetic underlayment provides better traction for roofers to walk on than felt underlayment during installation. This decreases the chances of anyone slipping and getting injured on the job.
There are different manufacturers of synthetic underlayment and different qualities. For our purposes, we are going to show how much Sharkskin® underlayment costs:
For a more in-depth look at the differences between felt and synthetic underlayment, we suggest reading:
You have to consider the specifics of your home or project. There are situations when one underlayment type is more suitable than the other.
Felt underlayment is recommended when:
Synthetic underlayment is recommended for:
Determining the correct gauge for your corrugated metal roofing sheets can be a bit confusing at first, but don’t worry as it’s actually the easiest part.
First, as a reminder let’s give you a cliff notes version of panel gauges. The thickness of the steel is called the “gauge” and as the number gets higher the thickness actually lessens. For example, 26 gauge is lighter than 24 gauge.
If you decide to use a corrugated roofing panel, you will have the most gauge options of any metal roofing panel. This is one of the few panels that is made as light as 29 gauge and as heavy as 20 gauge. Don’t let this intimidate you because a lot of these choices will actually be made for you based upon the paint system and color that you choose.
We actually recommend you decide upon the panel type, color, and paint system before worrying about the gauge for this reason.
The gauge that you need for your home will be determined by the type of installation.
There are different requirements for these two types of installations:
If you’re looking for a roof for your home, then the vast majority of times you will fall under this category. This is when the structure of the roof is a plywood deck and there is a roofing underlayment that’s installed between the plywood and the corrugated metal roofing panel. The strength of the roofing panel isn’t as important in this application. Most metal roofing that attaches to a wood substrate is 29, 26, or 24 gauge.
There are two articles, linked below, that talk about this in great detail so we are only going to briefly discuss why the lightest and heaviest gauges should be eliminated.
If you decide on using a light 29 gauge steel, your roof will be more susceptible to wind damage, more likely to dent during a hail storm, and will have lower snow load capabilities. The result for you is many more problems. You will see a $500 to $1,000 savings on the total installed cost of the roof, but it’s just not well-spent money.
The opposite side of the spectrum is a heavy gauge steel in 20 or 22 gauge. The only downside to a heavier gauge is the cost, but realistically for most homeowners it will not make much of a difference unless you have possible hail concerns. Purchasing a heavier gauge than you need is usually an unnecessary investment.
That really leaves most homeowners with the choice of whether you should use 26 or 24 gauge steel.
Either of these thicknesses offer you with a quality panel at a fair price point.
Some circumstances and climates would make 24 gauge your best option
In other instances, a 26 gauge material might be the best choice
Both gauges of steel are a solid and high-quality product. In the end, it comes down to budget, paint finish, and climate. If you want a much more detailed analysis of determining the best gauge for your project we recommend these two articles.
What Gauge Metal Roofing Should I Use For My Corrugated Roof?
What Gauge Metal Roofing Should I Use? (26 Gauge v. 29 Gauge)
When corrugated metal roofing panels are installed over metal purlins or wood, the strength of the panel becomes critical. The roofing panel has to span the distance between the metal purlins and also handle the load and wind uplift. As the supports are spaced further apart, the gauge of the roofing material will have to increase to accommodate.
We suggest you hire an engineer or look at the online load charts and wind uplifts to determine which gauge is best for your home.
We give you our expert opinion about the factors you should consider before making your final decision on a color for your metal roofing project. Learn about the following factors:
The main benefit of corrugated metal roofing is it’s an inexpensive metal roofing panel that’s easy to install. It’s about half the price of standing seam and it’s something that you could install without hiring a roofing contractor. Even if you had to hire a roofing installer, the labor costs are very reasonable.
Determining the cost of corrugated metal roofing is not a simple and straightforward answer. There are a lot of factors that will increase or lower the cost of the panels. Our goal in this chapter is to explain all of your options from the cheapest panel to the most expensive panel.
By the time you’re done reading this, you will understand the differences and how to spend your money.
There are lots of factors that go into the cost of a corrugated metal roof. Here is a range of pricing that you can expect to pay.
If you would like an in-depth article that gives more specific price ranges we suggest the eight-minute video above or the article that is linked below.
How Much Does Corrugated Metal Roofing Cost? Includes Pricing & Factors
Not all metal roofing installations are the same. Some metal roofs are simple, while others are difficult installations that require more time and labor. As a rule of thumb, the installation cost for a metal roof will range between $3 and $6 per square foot excluding the cost of the panels. This is why it’s important to get more than one bid.
Wondering if your cost will be on the high or low side of the installation cost range?
Here are the factors that will affect the installation cost of your metal roof:
As the roof gets steeper the cost to install it goes up. This occurs when the roof is not “walkable”; this is a roof with a pitch that’s too steep to safely walk on it. It’s a loose definition, but when the roof reaches a pitch of somewhere near 8” in 12”, you will not have a walkable roof. This requires a more experienced crew and the panels take longer to install.
The most time-consuming part of the install is the corrugated metal roofing flashing. The easiest kind of roof installation is one that only requires eave, gable, and ridge cap. The most difficult installation is a job with numerous peaks and valleys. This is where two planes come together and it’s the most likely leak point on the roof. It takes more time to install these areas correctly.
If you have an existing shingle roof that will need to be removed before installation, it will cost you more money. However, you are also eliminating any future problems by removing it versus installing it over the top of it.
Small jobs cost more to install versus large jobs. If your job is under 1,000 square feet, it could cost at least 50% more per square foot when compared to a job that is 2,500 square feet or larger. It’s hard to make any money on a small job. Therefore, contractors charge more to make it worthwhile.
As mentioned earlier, the right panel thickness for your metal roof will be dependent upon the type of installation, environment, and your budget. When you buy a corrugated metal roof you have more gauge options than any other type of roofing panel.
As discussed, corrugated sheet metal is available as light as 29 gauge and as heavy as 20 gauge.
How gauge impacts the price for corrugated metal roofing panels:
In our opinion, 26 gauge is the best mix of strength and price. It costs 10 cents to 15 cents more per square foot when compared to 29 gauge, but provides you with much more strength.
Both SMP and PVDF paint systems are high-quality products, but depending upon your specific needs one might be a better fit than the other.
PVDF panels are known as the best metal roofing paint finish. The main disadvantage of PVDF is they cost more. The biggest advantage is the color fades at a less rapid pace.
If you just want the least expensive metal roofing and don’t care about the way it looks, then galvalume is the best fit for you. You can buy a 29 gauge panel at Lowes for $1.25 per square foot and it will cost even less from a manufacturer.
These panels aren’t painted and will be bright and shiny. You will see them used on a commercial application more often than a residential application. Most residential roofs need to be painted so that they blend in with the overall look of the house.
Corrugated metal roofing at Home Depot will be a light gauge steel. Typically, they have ten-foot sheets in stock. These corrugated sheets are usually galvalume and 29 to 30 gauge thickness. This is perfect for an inexpensive fence or patio cover, but not an expensive roof that should last fifty years or more.
Purchasing 29 gauge material will only save you 10 to 15 cents per square foot versus 26 gauge. If you had a two thousand square foot house your installed price with 29 gauge material would be $10,000 to $16,000.
Using 29 gauge material is only going to save you a couple of hundred dollars on the bottom line price of your roof. This type of material is a bad investment as a light gauge roof because it’s not long-lasting, durable, or designed for high winds or heavy snow loads.
If you are considering using light gauge corrugated metal roofing then you should understand the applications in which it will and will not make sense.
What Gauge Metal Roofing Should I Use? (26 Gauge v. 29 Gauge)
In this section of the article, we only briefly touch upon what gauge is best for your project. It’s an important decision and should be researched further.
What Gauge Metal Roofing Should I Use For My Corrugated Roof?
When you are determining which corrugated metal roofing product is right for your roof there are tons of options, but these are your most likely scenarios:
Purchasing a corrugated metal roof is a large investment that could easily cost you $10,000 to $30,000. Spending that kind of money on your home gets you thinking, “Is buying a metal roof a good idea?”
Yes, a metal roof adds more resale value than doing an upscale to mid-range kitchen or bathroom remodel according to a 2020 study done by Remodeling Magazine.
Yes, there is research that clearly shows that a metal roof increases the resale value of a home. A study that was done by Remodeling magazine and published by the Metal Roofing Alliance determined that there is a high rate of return for the metal roofs cost.
The recouped resale value comes in around 85.9% according to national averages, with homes in the Eastern states recouping up to 95.5%. Houses that have metal roofs gain up to 6% more resale value on average over homes with asphalt shingles.
When you are trying to determine if a metal roof will pay for itself ask yourself this simple question. Do I plan on living in my house for 15 years or longer? If the answer to this question is “Yes”, then it’s a no brainer and a metal roof will be a better investment than an asphalt shingle roof. If the answer is “No”, then maybe it’s not a good investment.
If you are going to purchase a new metal roof, it will cost you $15,000 to $40,000. You want to make sure you’re spending your money wisely.
If you would like a much deeper dive into metal roofing ROI and if it increases property value we recommend:
So, you may have asked yourself, why is it important that I plan on living at my house for 15 years or longer. According to the Metal Roofing Alliance, a metal roof will last 30 to 50 plus years and an asphalt roof will last 12 to 20 years.
Let’s take the average of both of these numbers and see how that works out. Assuming the lifespan of the asphalt roof is right in the middle at 15 years and the metal roof is at 40 years. With an asphalt shingle roof, you buy the first roof and then 15 years later it’s time to install a replacement roof. That’s two roofs within 15 years.
I am sure you are skeptical when you read an article written by a metal roofing manufacturer that says a metal roof will save you money when compared to an asphalt shingle roof. I would be too, so I am going to lay out the numbers and clearly demonstrate that metal roofing is a remarkably better deal.
It’s important to note the rising cost of roofing panels over time as well. What an asphalt shingle roof cost today isn’t what it will cost 15 or 30 years from now. Pay close attention to the comparison below.
The average cost and lifespan for a 2,500 square foot house in corrugated metal roofing.
When you look at the numbers above it’s clear as day. If you plan on living in your house for more than 15 years a metal roof will be a great long term investment.
Just in case, you need more convincing, here are some additional cost-saving benefits from a metal roof:
If you would like a much deeper dive into metal roofing ROI and if it increases property value we recommend reading:
Purchasing corrugated metal roofing sheets or panels is typically not a simple transaction like buying something from Amazon. It’s too complicated to price online because each job is made custom to your order. Your specific order is customized by panel type, color, gauge, sheet lengths, trim, and accessories.
In this chapter, we will explain how to buy a metal roofing job from start to finish including:
You cannot go down to your local hardware store and pick up all of the corrugated roofing sheets and trim pieces that you need for a metal roof. There are plenty of creative ways to use corrugated metal panels where it would be possible to buy your needed material for a smaller project, such as a bar or shed, at the local hardware store. However, a larger project like a roof requires placing an order with a metal roofing manufacturer, a metal roofing distributor, supplier, or through your roofing contractor.
It’s time to talk about the four main purchasing channels.
Finding a metal roofing manufacturer that sells directly to the public is your best option to save money on your metal roof. Buying directly from the manufacturer will save you 15% to 50%.
Most metal roofing manufacturers do not sell directly to homeowners. If you spend some time researching you can find a few, but it’s the exception to the rule. Just keep in mind that the manufacturer does not figure out what you need. It’s your responsibility to provide a materials list.
At Western States Metal Roofing we are a manufacturer that sells directly to homeowners, roofing contractors, and general contractors. When you purchase directly from a manufacturer like us, it will save you money. Just make sure that you check their google reviews to verify you are dealing with a reputable company.
If you aren’t capable of supplying a materials list, then purchasing the material through a distributor is your next best bet. They act as a middle man and offer their expertise and guidance. In most instances, they will help you determine the necessary materials and will then order the material for you. Typically, there will be a markup on the metal roofing that’s normally in the range of 15% to 50% depending upon the size of the job.
This is the best option for you if you’re not working with a roofing contractor and want someone else to provide the materials list, figure out the trim, and do the leg work. A distributor or supplier offers a great service at a fair price.
When you get a quote for your metal roof, the roofing contractor will give you a complete price including materials and labor. Normally, the roofing contractor will have a 10% to 20% mark up on the metal roofing panels.
When purchasing material from roofing contractors, there are two things to consider:
At Western States Metal Roofing we have designer colors and finishes that other suppliers cannot duplicate. It’s common for a homeowner to find one of our colors online and then instruct the roofing contractor to purchase it from us.
Quite often, the contractor will provide a labor only bid and the homeowner will purchase the roofing panels directly from us with a materials list that was provided by the contractor. If you’re not happy with your contractor’s color selection this can be a viable alternative.
If you need material quickly, then your local Home Depot or Lowe’s typically will have material in stock. As mentioned in Chapter 6, you will not have any options though as they only carry 29 gauge galvanized corrugated.
The process of purchasing metal roofing is different depending upon the type of vendor that you will use. Purchasing metal roofing through a distributor, supplier, or roofing contractor is simple. Basically, you pay them a premium to help you figure out what exactly you need. But what does the process look like for you if you purchase metal roofing directly from the manufacturer?
The main disadvantage when purchasing directly from the manufacturer is that you need to know exactly what you need. It’s the homeowners responsibility to provide the manufacturer with a take-off or materials list.
This is a list that contains the materials needed for your job such as: how many panels, sheet lengths for each panel, list of trim and flashing pieces, the pitch of your roof, metal roofing underlayment, and accessories.
If you generally know what you need, but require a little help and guidance, then a manufacturer will typically provide enough help to bridge the gap. At Western States Metal Roofing, we are always happy to answer basic questions and steer our customers in the right direction. However, if you have no clue of what’s required and you cannot provide a materials list or take off than you have four choices:
Metal roofing will require a 2 to 3 week lead time plus transit time. Every job is different, so there is no way to keep material in stock except for possibly light gauge and galvanized. If you are building a house that will have a painted metal roof then you need to plan ahead.
The delivery of your corrugated metal roofing panels is often an overlooked part of the buying process. It’s also something that often does not get discussed or priced into the initial quote. When you are pricing your metal roof we recommend that you let the seller know where the project is located and to discuss the delivery access.
Always verify that your pricing includes delivery. Freight charges vary from as low as a couple of hundred dollars to as high as thousands of dollars. Some manufacturers will include the freight in the total price, list the freight as a separate line item, add it after the fact, or assume you will pick up the material yourself. This can make it difficult to compare bids and it leaves you vulnerable to a big sticker shock when you pay for the roofing panels.
Metal roofing does not always need to be delivered. It can also be picked up at the supplier’s facility. You will need a truck that is appropriate to haul the material, but if you have a smaller order and a truck you can avoid that expense. In most instances, the panels will need to be delivered to your residence.
The delivery of the metal roofing is the responsibility of the supplier up until the point that it arrives on the job site, aka your house. The offloading of panels is the responsibility of the purchaser. Any damage that is incurred after the material arrives on-site and during offloading is also the responsibility of the buyer.
Here are some important factors you should consider regarding the delivery of metal roofing panels
The truck does not come with a forklift. It’s the buyer’s responsibility to have the equipment and people onsite to offload their purchased material
Delivery to residential job sites is difficult. Most times the roofing panels are delivered on a full-size big rig. These trucks require a lot of space and need to be able to turn around. In most instances, they will not fit or are not allowed in a residential neighborhood. Sometimes the material can be shipped on a smaller truck, but that’s not always possible and could cost more money.
The buyer and seller should discuss this early in the process so that the appropriate freight rate is quoted. Sometimes the material will need to be shipped to an alternative location on a larger truck and then transferred to a smaller truck for delivery to a residence. Alternate delivery locations include your roofing contractors facility or local lumber yard.
Delivery is the last part of the buying process, but it’s the one that causes the most problems. Both parties need to work together to ensure the delivery truck has access, equipment, and contact information.
