Roof shingles deteriorate over time for various reasons. A common issue with shingles is blistering, which is typically caused by insufficient ventilation and trapped moisture. Shingle blisters can worsen in extreme weather conditions, such as harsh summer heat or heavy hailstorms. 

Although shingle blisters may not require a repair or replacement, it’s crucial to understand how they can be addressed. 

Things You Should Know About Shingles

Standard asphalt shingles have two layers: the backing material and the outer granule layer. During the manufacturing process, large rolls of uncut sheets of backing material are fed onto rollers and soaked in hot asphalt. Then, a layer of granules is applied on one side of the still-wet sheets. These granules protect the outer layer of the shingles from algae and ultraviolet (UV) damage. After cooling, the shingles are cut to size and laminated with another layer of granules.

Common Causes of Roof Blisters

Trapped moisture and insufficient ventilation are common reasons behind roof blisters in residential roofing systems.

When shingles are manufactured, moisture can get trapped within the shingles themselves. Once these shingles have been installed, they are likely to start blistering as the sun heats them up. Furthermore, if your roof is poorly ventilated, it can become too hot for the shingles, causing the blisters to enlarge and eventually pop. Once the shingle blisters pop, water could penetrate your roof, leading to damage that requires costly repairs or replacement.

How to Prevent Blisters From Popping

While the roof membrane can handle small movements and a few blisters do not necessarily affect the performance and longevity of your roof, make sure to be careful not to walk on the blistered shingles. Foot traffic can cause the blisters to pop, which will leave your roof exposed to the elements.

If trees surround your roofing, ensure that they are trimmed regularly so that the branches won’t poke your shingles and potentially pop the blisters. Lastly, make sure your roof is regularly inspected and maintained to keep track of any existing blisters. If you prefer to get rid of the blisters completely, it’s best to replace your shingles.
