What You Need to Know About Asphalt Shingle Blisters

Scheduling a roof inspection in spring is important because it helps identify issues that might compromise the health and performance of your asphalt shingle roof. With a gradual increase in temperatures, be on the lookout for patches of discoloration on your rooftop – this indicates blistering.

Why Do Asphalt Shingles Roofs Blister?

Asphalt shingle blisters occur because of the continuous exposure of the roofing material to the elements. Certain areas of the roofs’ surface may produce blisters due to trapped moisture, inadequate ventilation and poor roof installation.

During warm weather, trapped moisture gets heated, causing bubbles to form on the asphalt shingle surface that is covered with protective granules. They, however, collapse once temperatures drop at night. The expansion and contraction happening on the shingles remove the loosened granules, exposing the roofing materials’ matting.

Is It a Bad Thing?

Protective granules may remain intact even with evidence of blisters on asphalt shingles, which means they will not cause a problem for the roof and its longevity. Every residential roofing contractor, however, recommends addressing this problem sooner rather than later. Otherwise, the blisters may pop. As more and more granules are shed, and the roof undergoes continuous weathering, the popped blisters can let moisture in and cause leaks and other forms of roof damage.

Preventing Roof Blisters

Roofing issues like blistering can be prevented through periodic inspections and repairs. Preventive measures, such as trimming trees, help reduce the risk of blistering caused by dried leaves, twigs and other debris.
