The right ventilation system is crucial for a strong roof but many home buyers and owners don’t understand how these systems work. The Asphalt Roofing Manufacturers Association’s (ARMA) latest whiteboard video outlines the components to a properly functioning attic ventilation system and the many ways it benefits a roof, such as protection against shingle deterioration and roof system damage.
“How Does Proper Attic Ventilation Protect my Roof?” highlights how a balanced system of intake and exhaust results in a continuous flow of air in an unconditioned attic, helping to reduce heat and moisture buildup year-round and prolong the life of the roofing system.
The video demonstrates how proper attic ventilation can assist in reducing energy consumption, and preventing mold, mildew and wood rot. Additionally, it can help prevent ice dams, which can cause leaking and costly damage to shingles, gutters, insulation and the whole roof system.
“Homeowners may not be aware of just how important attic ventilation is to the longevity and performance of their asphalt shingle roofing system,” says Tim McQuillen, ARMA’s director of technical services. “ARMA wants to educate homeowners on proper attic ventilation and why it’s important, as well as how to recognize the signs indicating it’s time to call a roofing contractor if there are issues.”
