What Is A Ridge Vent?

Ridge vents for metal roofs

A ridge vent is designed to allow air to flow freely from the attic. It’s made from a permeable material and is placed on top of the metal roofing panels at the ridge of the roof. The ridge vent is then covered with a metal ridge cap. The purpose of the ridge vent is to create constant air flow along the horizontal ridge of your home.

It allows the stale air in the attic to be drawn out on a year round basis. Only ridge vents can provide a constant flow of air along the entire horizontal ridge of your house.

Ridge vent is available for most popular metal roofing profiles such as: ⅞” Corrugated, R Panel/PBR Panel, Western Rib/7.2 Panel, and standing seam, and more.


How Much Does Ridge Vent Cost?

The cost of ridge vent is approximately $3.00 per linear foot. This means that an average size house would only cost $150 to $250 in ridge vent material. It’s so easy and quick to install that the cost of labor is negligible.


What Is The Purpose Of A Ridge Vent?

A ridge vent is designed to let warm and damp air escape from the attic. This will decrease the amount of moisture within the attic. Ridge vents also help to create a balanced temperature and can significantly reduce indoor pollution levels in your home. When installed properly a ridge vent will increase energy efficiency and lower your energy bill. In addition, it will keep bees, wasps, insects, and bats out of the attic.

The Benefits Of Proper Ventilation

When you are designing your home it’s unlikely that you have given much thought to attic ventilation. It would be a costly mistake to overlook attic ventilation because the proper amount of attic ventilation will help to protect the entire house.

The appropriate amount of attic ventilation will help you maintain a more comfortable living environment within the house. Ridge vents help to reduce the amount of heat and condensation that can accumulate over time.

During the day, the heat generated from the sun accumulates in the attic and radiates your house. This can cause moisture that could create numerous problems like mold or mildew, rust, decreased air quality, and possibly structural damage. Mold or structural damage is expensive to fix and having a vented ridge will decrease the likelihood of these problems.

Furthermore, you want to prevent the insulation in the attic from getting wet. Wet insulation will lose its ability to insulate. Also a lack of attic ventilation is one of the main contributors to ice damming which can cause expensive damage to your home.

  1. Allows the heat to escape the attic which will prevent damage caused by snow, ice, and moisture.
  2. Lowers energy costs.
  3. Continuous airflow which increases energy efficiency
