3 Reasons Behind Asphalt Shingle Blistering

Your roof is at risk when blisters begin to form on your asphalt shingles. To address this issue, you must first understand how the damage on your roof manifested in the first place and how our roofing experts can help treat it. Polk Contracting Inc., your top roof insurance restoration contractor, discusses more.

Trapped Moisture

When your gutters are blocked, your shingles don’t get the opportunity to dry up due to water backing up from these metal channels. This causes your asphalt shingles to trap moisture. And when exposed to heat or sunlight, your damp shingles will expand and later on, begin to blister.

Poor Ventilation

Attic ventilation also plays a role in shingle blistering. That’s because fluctuating temperatures in your attic affect your shingles that sit atop it when warm air begins to build up in this part of the house. The intense heat will affect the integrity of your asphalt shingles and damage them from below.

Manufacturing Defect

Although a rare occurrence, manufacturing issues may have something to do with your blistering shingles if you don’t see any signs of trapped moisture or inadequate ventilation. Call your trusted roofing contractor for an immediate inspection and have your shingles replaced.

Prevention Tips 

It isn’t healthy for your roof to have blisters because these blisters can pop at any given moment. When they do, your roof is exposed to harmful UV rays and weather conditions, which causes leaks and severe roof damage. Thankfully, you can avoid it by keeping your gutters clear before a storm hits, observing proper roof maintenance and regularly checking on your attic ventilation.
