Asphalt shingles are one of the most popular roofing materials on the market due to their looks, durability and versatility. If they’re maintained by a seasoned roofing contractor, you can expect your asphalt shingles to last for years on end. However, one of the most common issues that affect them are blisters. But what causes these?
What Are Shingle Blisters
Blisters form on your asphalt shingle surface due to adhesion loss. Air pockets tend to form on the surface and create bubbles on the shingle surface. While some would consider this as a cosmetic defect, this could lead to serious issues later on in your roof’s lifespan.
Your roofing contractor would tell you that the protective granules of your shingles can accumulate in your gutters when the shingles blister. This allows water to clog up your gutters and back up onto your roofing system, leading to roof leaks and a myriad of water-related issues.
What Causes Asphalt Shingle Blisters?
Poor Installation Work
If subpar contractors work on your asphalt shingles, they might not properly secure it, leading to problems in the future. In fact, a slight discrepancy on the measurements can cause your asphalt shingles to form blisters down the road.
If there is too much moisture in your attic, the trapped heat will try to escape through your shingles, leading to air pockets forming “bubbles” that may pop.
It’s important to ensure that your roof is properly ventilated to allow trapped heat to escape your home. This prevents your shingles from expanding and keeps your home comfortable as well.
