Why Do Asphalt Shingle Roofs Blister?

As a homeowner with an asphalt shingle roofing system, blistering shingles is likely something you have come across. It is one of the more common problems that affects asphalt shingles today. You may be wondering about its cause and if there are any ways to prevent its occurrence, or at the very least, the proper way to get them fixed before they worsen.

Read on as your trusted roof replacement expert, Cosmic Renovation & Roofing, lends a professional opinion on the matter.

Causes of Blistering Asphalt Shingles

Blistering shingles come down to two main causes:

  1. Trapped Moisture in the Shingles – In some instances, moisture can get trapped in the shingles during the manufacturing process. In this case, there really isn’t much you can do regarding prevention. This is because if the shingles on your roof have trapped moisture, then they will likely start blistering as the sun heats up the shingles. The heat causes the trapped moisture to heat up as well, which can result in blisters rising up on the shingle.

  1. Poorly Ventilated Roofs – An asphalt shingle roof that does not have a proper ventilation system in place can get too hot for shingles. Without an adequate outlet for built-up heat to escape, the intense heat can eventually cause the shingles to blister. That’s why here at Cosmic Renovation & Roofing, we always emphasize proper installation and regular inspections, not just for asphalt roofing systems, but all the roof types we handle, including our solar services.

Prevent Blisters From Popping

If you already know that some of the shingles on your roof are blistering, consider these helpful tips to prevent them from popping:

    • Do not walk on the blistered shingles as they can easily pop with the weight of foot traffic.

  • Protect your shingles from falling debris like pine cones, acorns and limbs by pruning surrounding trees.
