Blistering is one of the most common issues with asphalt-based roofing systems. To this day, there are still homeowners who think that popped roof blisters are signs of hailstone damage. But this is not the case at all. This is a problem that residential roofers often encounter particularly during the summer season. If you want to know what causes roof blisters and what can be done to prevent it, then keep on reading — this post will guide you through.



What Causes Asphalt Roof Blistering?

For strength and performance, manufacturers build asphalt shingles using three equally important layers. These are the paper or fiberglass backing, asphalt and granules. Sometimes, during the manufacturing process, errors can occur and result in getting air or moisture trapped between these layers. Once installed on your roof, exposure to long, hot days in the summer causes the air or moisture to expand. This ends up being blisters on the roof surface.

Another key factor roofers will tell you to consider is attic ventilation. Too much heat inside the attic will only exacerbate the current condition of these roof blisters.

How Can Asphalt Roof Blistering Be Prevented?

If you want to avoid dealing with roof blistering, the first thing you have to do is choose high-quality asphalt shingles. A well-designed shingle is durable enough to deter blister popping. Proper installation should also be observed, so make sure to hire a professional who strictly adheres to manufacturer specifications.

Scheduling regular maintenance can help you detect early stages of blisters. Since roof repair experts are trained to deal with different roofing issues, they can also provide long-term solutions for your home. They also understand that movement on the roof needs to be as limited as possible because blisters can pop even from slight impact during an inspection.
