Causes and Solutions to Asphalt Shingle Blisters

Shingles will weaken due to extreme weather conditions, prompting repairs and even replacements like any other material. Having your system renewed will be inevitable as blistering and swelling are likely to occur. Today, your local roof and siding installers delve into asphalt shingle blisters and how you can efficiently deal with them. 

Common Causes of Blisters

Asphalt shingles are made of three layers— the outermost layer is the granules with the roofing colors and other features, while the asphalt is sandwiched between these layers. Its backing material may be made of recycled paper or fiberglass. Experts say that moisture can be trapped between the sheets because of manufacturing errors or inadequate installation, moisture can be trapped between the sheets. When shingles are exposed to heat, the moisture expands, which causes blistering.

1. Blisters can form on a scorching roof surface, making poorly ventilated roofs prone to this particular problem. Moreover, blisters are raised areas where there is a lack of system adhesion. They usually contain trapped moisture or air and look like bubbles on your roof. When neglected, they will enlarge, letting more water penetrate the membrane, resulting in a roof replacement.
2. Improper installation work can leave small empty spaces in your roof that may contain pockets of moisture. When the sun heats the shingles, pressure in these pockets may rise and elevate the surface, which results in blisters.

Addressing Blisters

If you only have blisters in a particular part of your roof, be cautious walking on the blistered shingles to avoid popping due to foot traffic. By then, clear overhanging branches and debris in the area to prevent further damage.

Moreover, the best way to deal with blisters is to call for a contractor. Prioritize scheduling routine inspections because these can save you money in the long run. After all, these precautions can only stop the problem from becoming worse.
