Roofing services > Residential > Attic ventilation
Why is ventilation important for your roofing system? Without adequate ventilation, your attic retains heat and moisture, increasing your expense for keeping your house cool, providing a breeding ground for mold and mildew, and shortening the lifespan of your shingles. Heat in unventilated attics can cause temperatures to exceed 140 degrees causing shingles to curl and bend. An attic, properly ventilated, provides a constant stream of air through the attic space. Ideally, ventilation consists of 50% intake under the eaves, and 50% exhaust near or at the roof peak – at least three feet higher than the intake system.
