Video: The Importance of Roof Ventilation

SOUTH SAN FRANCISCO — Host, Sarah Rutan: If you’re planning for a roof replacement, one thing you should discuss with your contractor is ventilation. Today we’re in South San Francisco with Diamond Certified Expert Contributor Carlos Rodriguez of Mr. Roofing to learn more.

Diamond Certified Expert Contributor, Carlos Rodriguez: Ventilation is a critical component to all roof systems, especially for the longevity of the roof and also to keep everyone healthy inside the property. If you don’t have proper ventilation, condensation starts to form and drip literally, and mold and mildew can start to grow. And that will affect or deteriorate the roof system, as well as affect people’s health causing asthma, allergies, etc.

There is a clear-cut formula on ventilation. There has to be a balance of cool air intake and exhaust so that air can circulate and keep things from growing. Also, to keep hot air out so it doesn’t prematurely deteriorate the roof materials. If your roofing professional is not talking about ventilation, it should raise a red flag for you because it’s very important for the longevity of the roof system and the health of the inhabitants.
