Blistering is among the most common problems that occur in asphalt shingles. You’ll know your roof has blisters if there are raised spots or bubbles rising up from inside the shingles. This issue can occur for various reasons and sometimes, it affects more than just the appearance of your roof.

Why Do Asphalt Shingles Blister?
Trapped Moisture
During the manufacturing of shingles, it’s possible for moisture to get trapped within them. When this happens, the shingles are more likely to get blisters after installation. It’s because when the sun heats up the roof, the trapped moisture in the shingles also increases in temperature. As a result, blisters will start to develop.
Lack of Ventilation
You can avoid different moisture-related problems in your home by making sure your roof and attic have sufficient ventilation. If your roof doesn’t have sufficient ventilation, it can increase in temperature. Excessive heat and moisture can contribute to shingle blistering. A reliable roofing company will help you ensure you have proper ventilation to avoid this issue.
Should You Be Worried About It?
You should not be worried if the shingles with blisters have retained their granules. However, the time will come that the blisters on the shingles will eventually pop. When this happens, the granules will fall off, which exposes the shingles to the sun’s harmful UV rays. The exposed shingles will then become more prone to damage and leaks.
Anyone walking on the roof must be careful to prevent the shingles from popping. It will also help to keep trees around your property trimmed. Debris such as fallen branches and pine cones can pop blisters on shingles.
