Why Do Asphalt Shingle Roofs Blister?

Blistering asphalt shingles are one of the common problems you have to deal with when it comes to your roof. Sometimes, the blisters are not a cause for immediate concern until they get popped by the impact caused by falling debris or hail.

Causes of Blistering Shingles

Without proper care, even asphalt shingles of the highest quality can sustain blisters. Here are the common causes of this issue:

  • Poor Ventilation. When there’s inadequate airflow in the attic, trapped heat can raise the roof temperature, causing the shingles to blister. It can also impair other components, such as the eaves, rafters and insulation, which can shorten the life of your roofing system and increase your energy bills.

  • Trapped Moisture. There are times when moisture can get trapped in the shingles during the manufacturing process, which can affect the way they look. The trapped moisture will then expand when exposed to excessive from the sun, resulting in blisters.

It can be confusing to distinguish blisters from hail damage, however. To differentiate the two, take note that blistering shingles are likely to be surrounded by unaffected ones, while hail-damaged shingles have indentions around the area or on a particular slope.

How to Prevent Blistering Shingles

Just like your replacement windows, it’s essential to put your roof on top of your maintenance list. Be sure that your attic has proper ventilation to maintain your roof’s structural integrity. You should also cut all the overhanging branches surrounding your home.

Apart from this, it’s best that you invest in high-quality roofing products like Owens Corning as they undergo a stringent manufacturing process to minimize the risk of blisters. It’s also imperative to hire a certified roofing contractor like us to make sure that your roof is flawlessly installed.
