  Western Lock® Standing Seam
• Features & Benefits

  Features & Benefits of Standing Seam Metal Roofing

  • High Seams - High seam panels have a greater benefit versus a lower seam panel for moisture penetration. Seams also known as ribs are raised to prevent water penetration and help prevent water leakage into the interior, and diverts water down the roof to a drain point.
    
  • Fasteners/Clips – Western Lock standing seam has a concealed clip system and is one of the most durable and weather resistant roofing system available.
    
  • Fewer Seams - Because the metal panels run unhindered from the top to the bottom of the roof, not only are there no horizontal seams but, in total, the roof has a fewer number of seams.
    
  • Corrosion & Rust Resistance – Our metal roofing and siding panels and sheet steel products are coated with an aluminum-zinc alloy coating (AKA Galvalume®/Zincalume®). This creates extraordinary outdoor corrosion resistance.
    
  • Durable - Metal Roofing coated with an aluminum-zinc alloy coating (AKA Galvalume®/Zincalume®) will have an exceptionally long life expectancy.
    
  • Pest and Termite Resistant - Bugs, pests, and termites cannot penetrate through metal materials making a standing seam metal roofing system your best defense against unwanted creatures.
    
  • Fire Resistant - Metal roofing and metal wall systems are noncombustible. They have a Class A fire rating. Class C rating when applied over a combustible material such as wood shingles.
    
  • Wind Resistant - Metal roofing can withstand powerful wind gusts.
    
  • Lightweight - Lightens the load in installation and reduces the load bearing weight on support walls and beams.
    
  • Stylish – Available in various colors and can be ordered in a variety of premium specialty finishes. Standing seam roofs are perfect for certain types of contemporary or country-style houses. Due to the smooth, straight lines, these roofs give your house a stunning appearance with a modern flair.
    
  • Energy Efficient - Metal roofs with a "Cool" paint finish reflect solar radiant heat, which can help reduce cooling costs.
    
  • Eco-Friendly - Metal roofing is made from recycled content. Western Lock standing seam panels are also recyclable at the end of their life as a roof. In contrast, most shingle tear-off waste ends up as part of the building-related waste stream - up to 20 billion pounds per year.

WHAT IS A MECHANICALLY SEAMED CONCEALED FASTENED PANEL?

• Single lock refers to ONE fold of the seam (or 90 degrees).
• While single lock profiles won’t perform as well as a double lock, single lock still performs well in milder environments. Again, check to make sure the engineering allows a single lock to be used.
• Single locked systems require less labor, and it’s easier to replace a damaged panel than double lock profiles.

• Double lock mechanical systems feature TWO folds of the seam (to achieve 180 degrees).
• Double lock systems are suitable for low-slope applications needing extra weather-tightness.
  • 2-inch double lock profile: Can generally be installed down to a .5/12 pitch with in-seam sealant (based on geography).
  • 1.5-inch double lock profile: Can generally be used down to a 1/12 pitch with in-seam sealant (based on geography).
• Double lock panels perform better; plus, there is less of a chance for panels to come un-seamed.
• For properties in cold weather areas with freezing and thawing, double lock systems are good choices. As snow/ice freezes and thaws, it also expands and contracts, which could potentially disengage a snap-lock profile.
• Double lock panels are more labor-intensive to replace.
• When possible, you should use an expansion clip with a mechanical lock profile.
  

More Options for Standing Seam Systems

• Flat – No indents between the clip relief ribs
• Striated – Small consistent indentation lines in the panel
• Ribbed – Shapes or indentations between the seams
  • Pencil – Circular panel indents
  • V-Ribs – “V” shaped panel indents
  • Bead – Longer, rectangular panel indents
• Clip relief – A stiffening rib adjacent to the seam that allows the space for a clip underneath
