Have you checked your roofing system lately? If the asphalt shingles have come to develop small, pimple-like protrusions on their surface, that can only mean they’re already compromised by blisters. There are a few reasons why this problem can happen.

- Moisture in the Asphalt Shingles
There are cases where excess moisture becomes trapped in the asphalt shingles during the manufacturing process. This increases the risk of blistering later on in your roof’s lifespan. That’s because the shingles become exposed to the sun after they’re installed. As sunlight heats up the roofing material, it also does the same thing to the trapped moisture, which may rise to the surface in the form of blisters.
- Poor Attic Ventilation
Because the attic is an enclosed space, heat can build up inside unless the intake and exhaust vents are working properly. And if they’re not, the heat becomes trapped and bakes the asphalt shingles overhead, causing them to blister. Because the roofing material has weakened, it may not be as effective at resisting inclement weather.
Fortunately, you can take measures to minimize the problem caused by blistering. If your asphalt shingles already have blisters, take care not to pop the blisters. Otherwise, the shingles will lose their protective mineral granules, making them more vulnerable to weather damage. But this is only a temporary solution – those blisters will eventually pop due to foot traffic, fallen debris or impact damage caused by hailstones. You’ll need to get a new roofing system once that happens.
