Attic ventilation is one of those things you might not always think about, but nonetheless, it plays a vital role in your home. One of its primary functions is to help ensure your roofing system’s longevity and performance. By promoting air circulation in and out of your attic, you also help boost your home’s energy efficiency and comfort.

Here’s why attic ventilation matters for your roofing system (and your home).

How Attic Ventilation Works

A well-built residential roofing system has a balanced set of vents that promote air circulation within the attic. Intake vents, which are found under the roof eaves, draw cool, fresh air into the attic. It then pushes out warm, moist air out of the space via the exhaust vents, which are located at the highest point of the roof.

Benefits of Proper Attic Ventilation

There are some significant benefits to having a well-ventilated attic. These include the following:

• Helps Lower Attic Temperature
  A well-designed and well-functioning attic ventilation system can help evacuate superheated air from the attic, reducing the amount of work your air conditioner has to exert in the summer.
  
• Reduces the Risk of Ice Dams
  Proper ventilation allows chilly winter air to move through the attic, keeps your roof cooler and helps prevent the formation of harmful ice dams caused by the melting and refreezing of snow.
• Helps Protect Your Roof System
  The buildup of heat and moisture can put additional strain on your roof’s shingles and other components, increasing the risk of premature deterioration. You can safeguard your roof with a well-balanced attic ventilation system that allows cold, fresh air to enter the attic and expel superheated air.
