Asphalt Shingle Blisters: Causes and Prevention

Causes of Asphalt Shingle Blistering

Blisters may appear on your asphalt shingles as a result of any of the following:

  • Trapped moisture. One of the key factors contributing to asphalt shingle blisters is a poor manufacturing process. The shingles could become waterlogged during manufacturing. Your roof develops blisters when trapped moisture is heated up by the sun.
  • Poorly ventilated attic. Your roof or attic can get too hot without proper ventilation. This can cause roof blisters. Small blisters can cause granules to fall off shingles. If this happens, your roof will be open to harmful UV radiation.
  • Poor workmanship. Improper installation causes asphalt shingles to blister. Before having a new roof installed, be sure the roofing contractor you choose has the necessary experience and skills to do the job well.

How to Avoid Roof Shingle Blistering

  • Regular inspections. Investing in yearly roof maintenance and inspections is a wise move. Regular roof maintenance extends the roof’s longevity and catches problems before they become costly. Aside from preventing blisters, regular maintenance will give you peace of mind. You’ll feel better knowing your roof can withstand severe weather. Delaying roof repairs will only make any problems worse and more expensive.
  • Proper attic ventilation. Blisters on the roof and on the shingles can be avoided with proper attic ventilation. Get in touch with a roofing professional right away if there are any indications of moisture or leaks to avoid further issues like mold growth.
