Most roof installations rely on intake and exhaust vents in attics that draw cool air in and push humid, warm air out, respectively. They, along with vents installed on the roof, provide vital maintenance that helps you maintain a comfortable, healthy, energy-efficient residence. Learn more about what makes proper attic and roof ventilation essential below.  

Why Is Quality Roof Ventilation Necessary? 

1. Prevents Warped Shingles

Shingles can warp and therefore appear wavy or buckled when your attic isn't properly ventilated. Damp air cannot escape efficiently, and saturates shingles instead. The more moisture the shingles absorb, the more likely they are to warp and curl. 

Roof leaks typically result because the shingles are no longer flat to provide protection from the elements, which causes water damage and mold growth. Warped shingles also look unsightly and contribute to appearance issues, which is especially problematic if you are part of a homeowners association group and must follow various architectural and landscape guidelines. 

2. Helps Avoid Wood Rot 

If a roofing system is consistently exposed to hot, damp air, its rafters start to rot. Wood rot makes the material spongy and weak, eventually causing structural stability issues. Mold can also start growing on saturated rafters, since the fungus breaks down wood and other organic matter. 

Wood-boring insects, such as termites and carpenter ants, might find their way to roof rafters as well, since they are attracted to decaying wood. By allowing hot air to exit your attic through assorted vents, you are preserving your roof’s structure and preventing dangerous partial collapses. 

3. Contributes to Reasonable Energy Bills 

When hot air builds up in the attic, it causes the HVAC system to work twice as hard, since it attempts to cool off the space. When this happens, the energy bills may increase during the warmer months because the HVAC system uses more energy to combat excessively warm air. Venting the attic provides a simple way to maintain reasonable energy bills, which reduces your carbon footprint, in addition to saving money during summertime.
