To Get Rid of Heat
In hot weather, proper ventilation prevents the attic from becoming a “hot-box” that radiates unwanted heat down through the attic floor into the living area. Attic temperatures can reach 150 degrees without proper ventilation!
To Get Rid of Moisture
In cold weather, proper ventilation helps prevent moisture from condensing on the insulation, rafters, and roof deck. Trapped moisture can rot wood members and rob insulation of its
R-value.
