Blistering shingles are a common concern in asphalt roofing systems. These blisters shouldn’t affect the performance and lifespan of your roof as long as the granules remain on the shingles. However, once they pop, granules will fall from the roof, leaving the surface exposed to the harmful effects of the sun. When this happens, the affected area will only lose more granules, leading to leaks and damage.
Find out what causes this problem as well as how to prevent and address it from a trusted roof replacement company.
What Causes Shingles to Blister?
Without sufficient ventilation, your roof can get too hot. Over time, the increased roof temperatures can cause the shingles to blister.
Another cause of this roofing issue is trapped moisture in the shingles. In some cases, during manufacturing, moisture can get stuck in the shingles. These shingles are more likely to experience blistering. It’s because as they get exposed to the sun, the moisture inside heats up and causes blisters to develop.
How to Prevent This Problem
Regular inspections and maintenance from experienced roofing contractors can help with the detection of this problem while it’s small. Roofing products should also be checked for manufacturer’s defects before installation.
Blistered shingles should be carefully walked on as they are at higher risk of popping due to foot traffic. Trim down trees surrounding your home because branches, seeds, pine cones and other debris can cause the blisters to pop as well. You can also have the affected shingles replaced before they pop. However, you may want to consider a roof replacement if your current roof is reaching the end of its life or a significant amount of shingles are blistered.
