Causes of Asphalt Shingle Blisters

by

Having adequate knowledge about your asphalt roof can help you prolong its life span. Generally, asphalt shingles weaken due to extreme weather conditions. But apart from the harsh summer heat and severe hailstorms, there are other roofing problems you should look out for — such as asphalt shingle blisters. 

Causes of Asphalt Shingle Blisters

If you search “roofers near me” and ask them about asphalt shingle blisters, these are the top causes why this roofing issue occurs.

What You Should Know About Asphalt Shingle Blisters

  • When trapped underneath the shingles, moisture will eventually create blisters on your roof’s surface. Constant exposure to heat can also contribute to this.
  • While roof repairs can bring your roof back in good shape, it’s best to address the root cause of roof blisters — which is typically insufficient roof ventilation. Without proper ventilation, certain areas in your shingles could bubble up and develop blisters. These blisters may eventually pop, causing the granules to get dislodged. When this happens, your roof will lose a crucial layer of protection against the sun’s UV rays.
  • Sometimes, faulty installation is the culprit behind asphalt shingle blisters. Creases, leaks and blisters may appear if the roofing material is not installed correctly.

Addressing Asphalt Shingle Blisters

  • The roof membrane can handle small movements and would be able to withstand a few blisters. However, if you find several blisters on your asphalt shingles, you should call up a contractor to check whether a repair or replacement is necessary.
  • The best way to prevent blistering is to ensure your roof is installed correctly. Hire only a reputable and trained professional for your roofing project and make sure to have your roof regularly maintained as well.
