Over its serviceable life, your roof may encounter various problems, one of which is blistering. If your roof is made of asphalt shingles, you may have already encountered this problem. But what causes blisters to appear in the first place? Local roofing contractor Innovative Roofing & Siding, Inc. explains further.

Moisture
One of the biggest causes of asphalt shingle blisters is moisture. You may be thinking that your roof is almost always in contact with water and moisture so those factors are unavoidable. However, moisture trapped inside your shingles during manufacturing can lead to possible blistering in the future. Since your shingles are exposed to the sun’s heat, the moisture inside will heat up, creating blisters.
The best way to counter this problem is to choose a roofer that offers high-quality shingles. Such roofing materials will prevent you from having blister problems in the future.
Poor Roof Ventilation
Another cause of roof blisters is poor ventilation. Although you chose high-quality shingles, you may still encounter problems, especially when your roof doesn’t have enough vents to allow air circulation in and out of your attic. If this integral component of your roofing system isn’t letting fresh air in and stale, moist attic air out, excess heat and moisture can build up. The residual heat from the attic can rise and cause blisters on the shingles above.
Roofing problems are a result of subpar products or insufficient installation. To avoid such issues from causing your asphalt shingles to blister, hiring the right roofing professionals is very important. It may seem easy enough to do it yourself by following online tutorials, but having someone trained to do it will make your roof more efficient and better at withstanding the elements.
