Proper air circulation will greatly reduce the chance of leaking, blistering, curling and many other potential problems.To tell if a home’s ventilation is inadequate, several signs appear in the home’s attic.
Those signs include an attic that is hot and stuffy compared to the rest of the house, stagnant air, unbroken darkness indicating blocked or non-existent openings, and water stains/mold on the underside of the decking.
Why is ventilation so important? Ventilation is a crucial factor in the life of a roofing shingle. Heat build-up in the hot summer months, as well as the cold weather of winter will accelerate the aging process of your asphalt roofing shingles.
Proper air circulation, regardless of the weather outside, will greatly reduce the chances of leaking, blistering, distortion, curling, rotting of wood structure, wet insulation and many other potential problems.
