4 Issues You May Encounter With Poor Attic Ventilation

Poor attic ventilation can lead to numerous issues that might compromise your roof’s structural integrity and your home’s indoor comfort. Here are four things that may happen as a result of this problem.

Poor Attic Ventilation

1. Shortened Roof Lifespan

Too much heat and moisture inside your unventilated attic exposes your roof’s decking or sheathing to rot, which may shorten the lifespan of your roofing system’s important components – the shingles and the underlayment. Signs to look out for include cracked shingles and premature granule loss. Avoid early roof replacement by making sure your attic has air circulation.

2. Mold and Mildew

Any roofer will tell you that these are not only bad for your roofing system but also for the health of your household. Excess moisture brought about by lack of ventilation makes your attic the perfect place for mold and mildew to grow and thrive.

3. Ice Dams

Ice dams can cause detrimental water damage to your home if not addressed properly. They form when the bottom layer of snow on your roof melts, flows down your roof, and refreezes on the cold outer edge near your gutters. The snow melts from the hot air coming from your heated living areas rising up to your attic.

4. Sagging Decking

Moisture can seep into your roof decking when there is poor attic ventilation. It will then dissolve the adhesives on your roof and cause the wooden decking and shingles to warp and sag. While a roof collapse rarely happens as a result of this, you’ll want to have this problem addressed as soon as possible with the help of a reliable roofing company.
