Roof blistering is an unsightly and potentially concerning issue that can appear on asphalt shingles. But what causes them, and how serious are they really? In this post, A.O. Roofing will cover everything you need to know about roof blistering.
What Is Roof Blistering?
Roof blistering occurs when gas, air, or moisture gets trapped inside asphalt shingles, creating a bubble, blister. Over time, the blisters can pop, leaving a pockmark and damaging the granules of the shingle.
The main causes of roof blistering are manufacturing errors and ventilation problems.
Manufacturing errors include trapped moisture or gasses left in the shingle, an improperly cured fiberglass mat, or poorly mixed asphalt. When it comes to poor ventilation, the lack of airflow can cause the roof to overheat, causing the shingles to heat up and release gasses that form blisters.
Should You Be Concerned About Roof Blistering?
Roof blistering is certainly unsightly, but how serious is it really?
The short answer is, it depends.
In many cases, roof blistering is a cosmetic issue and nothing more. In other cases, it can be more serious.
The main concern is that popped blisters can shorten the lifespan of your shingles. This is because of the granules lost when the blister pops leave the shingle with less protection from UV damage and the elements. If blistering is widespread, it means your whole roof will deteriorate faster.
