Because your roof is a valuable investment, it is important to understand the roofing issues that may occur over time so you can address them properly. In this post, trusted roofing and siding contractor Sterling Exteriors sheds light on blistering, a common problem with asphalt shingles.
What Is Blistering?
Blisters on asphalt shingles are hollow, raised areas. While blisters do not pose an immediate risk, they will eventually pop, especially if the roof is not regularly maintained or roof repair is not prioritized. When shingles pop, the ceramic-coated granules become dislodged, exposing the underlying asphalt to harmful ultraviolet rays.
Why Do Blisters Form?
Heat and trapped moisture are the leading causes of blistering shingles. When heat from the sun causes pockets of moisture to expand, blisters ultimately form on the shingles. A hot attic is another primary reason why shingles blister. This is usually caused by insufficient ventilation in the space. That’s one of several reasons why it’s so important to ensure adequate attic ventilation.
Can You Prevent Blisters From Popping?
To minimize the risk of shingle blisters popping, be careful not to walk on blistered shingles. Also, keep any overhanging trees near your roof trimmed, as falling debris such as pinecones and acorns can accidentally burst the blisters, especially bigger ones. Blisters can also pop from the impact of hail stones, although there is not much you can do about that. The most effective way to ward off the effects of popped blisters is, of course, to replace the affected shingles before they burst.
