Blistering is a common problem with asphalt shingles and is something that you shouldn’t ignore. While it may appear like a simple aesthetic problem, blistering can affect the performance of the shingles and their operating life span.
Hinkle Roofing, your local roofing contractor, discusses what causes asphalt shingles to blister and what you can do about it.
Asphalt shingles can blister as a result of trapped moisture in the shingles. In some cases, moisture can get trapped within the shingles during the manufacturing process. When the sun heats the shingle, the trapped moisture will rise to the surface, causing the tell-tale blistering.
Blistering can also happen as a result of poor ventilation. When there’s inadequate ventilation in the attic or on the roof, the environment will become too hot for the shingles. This will eventually cause blisters to appear on the shingles.
Both situations are serious roofing concerns and have the same result: the shingles will start to lose their effectiveness and will have a shorter operating life span.
Blisters Are Bad
When the shingles blister, they can loosen the protective roofing granules which play an important role in waterproofing the roof. Roofs that lose their granules are also more susceptible to harsh sunlight, which further aggravates the weathering process.
Addressing the Problem
Unfortunately, when the roof shingles start to blister, you will eventually have to replace them as they may have already compromised the structural integrity of the roof. That said, you can avoid blistering in the first place by ensuring your roof and attic have proper ventilation.
