Ventilation is paramount to a healthy roof. After all, the roofing system can be exposed to heat coming from the inside as well as from the outside. But what is the exact role of proper ventilation in roof longevity? Here, Arrowhead Roofing discusses the most frequently asked questions about the subject.
Why Is It Important?
Any asphalt-shingle, wood-shake, tile, slate or custom metal roofing expert will admit that proper ventilation prevents heat buildup. Your attic can get really hot whether it’s summer or winter because the heat moves from the air into solid surfaces like the roof deck. The high temperature of the deck can then cause roofing components to overheat and deteriorate more quickly.
Having sufficient, balanced airflow can help moderate extreme heat and expel excessive moisture. The constant movement of fresh breezes into the attic and warm inside air to the outdoors serves as your roof’s cooling mechanism.
What Is the Best Ventilation System?
The market has no shortage of roof-ventilating components such as ridge vents and soffit vents. And some are admittedly more popular than others. However, any reputable storm damage roof repair specialists will say that no ventilation method is inherently superior to another. The right choice will always depend on the roof design and the local climate.
The only way to find out whether you have the most suitable ventilation system for your roof is to watch out for symptoms of inadequate ventilation.
What Constitutes Inadequate Roof Ventilation?
Ice damming is an indisputable sign of poor roof ventilation. This phenomenon occurs when there are uneven temperatures across the roof plane. The upper portions are typically hotter than the lower ones, and as a result the snow melts in the warm areas and freezes upon reaching the colder ones. When left unaddressed for too long, you might be forced to request a roof replacement estimate even if you’re not due for a new one yet.
