Attic Ventilation Systems
Attic Ventilation is one of the most, if not the most, important element in maintaining or reducing the energy usage of your home. As important as this topic is to our nation’s energy bill crises, throughout our experience replacing roof’s for home owner’s, we discovered many shocking situations.
- Nearly 90% of newly constructed homes do not meet the minimum attic ventilation standards
- Less than 10% of roofing contractors are providing accurate attic ventilation information to consumers
- 2 out of 3 home owner’s purchase the wrong type of attic ventilation system for their home
The picture that you see above is a basic demonstration of attic ventilation systems and the various effects of heat and moisture in and outside of your home. Of course every home does not have a simple roof structure like the images above; therefore, a proper thorough analysis is critical to more complex roofing systems. As GAF/ELK Authorized Installers we can provide a ventilation system requirement that’s specifically customized to your home and your needs.

The Least You Should Know About Attic Ventilation
The first thing you should know is that a lot of roofing companies that install ventilation materials don’t know the first thing about ventilation. We know this because we correct ventilation issues on dozens of houses every year that have had contractors address ventilation with the installation of ridge vents, making the ventilation properties of the house worse than when they started. So why does this happen? It happens because companies are being pushed to install products that they are not trained to install, based on limiting their liability. The end result can be very costly.
Here are a few very simple things to write down and quiz the contractor you may be talking to about ventilation.
What is a soffit vent?
Soffit vents are roof ventilation devices that are installed under neath the eaves of a roof that extend pass the warm wall line. These roof vents allow fresh air to enter into an attic (not the home) thus creating an air circuit, when they are properly combined with other types of roof ventilation devices. Almost all homes have some sort of roof ventilation devices installed throughout the roof. There is a verity of roof ventilation devices available in styles such as Wind Turbines, Electric Attic Fans, Solar Powered Attic Fans, Ridge Vents, Boxed Vents, and Hip Roof Ventilation just to name a few. When soffit vents and roof ventilation devices are combined properly, they reduce a home’s energy consumption and prolong the life span of the roof, A/C unit, and many other components of the building structure in such degrees that you just can’t afford not to use them.
