Choosing the right attic ventilation system is crucial to maintaining or reducing the energy usage of your home. Throughout our experience replacing roofs, we’ve discovered many alarming situations.
- Nearly 90% of newly constructed homes do not meet the minimum attic ventilation standards

- 2 out of 3 homeowners purchase the wrong type of attic ventilation system for their home
The picture that you see above demonstrates an attic ventilation system and the effects of heat and moisture in/outside of your home. We know that not all homes have a simple roof structure, therefore a thorough analysis is critical to handling more complex roofing systems. As GAF/ELK Authorized Installers, we can engineer an attic ventilation system that is specific to your home.
Attic Ventilation 101
There are many roofing companies that perform ventilation installations incorrectly. We know this because we correct attic ventilation installation issues on dozens of houses every year. So why does this happen? It happens because some companies are pushed to install products they are not trained to install and the result can be very costly.
Almost all homes have some sort of roof ventilation device installed on the roof. There are a variety of roof ventilation devices. Such devices include wind turbines, attic fans, ridge vents, and boxed vents just to name a few. Soffit vents are roof ventilation devices installed underneath the eaves of a roof that extend past the warm wall line. When properly combined with other roof ventilation devices, soffit vents allow fresh air to enter an attic creating airflow. They also reduce energy consumption and prolong the life span of the roof, A/C unit, and building structural components.
