Asphalt Shingle Blisters: Causes and Prevention

Asphalt shingles are a top choice when it comes to roofing. They offer versatility, weather resistance and other qualities that will help protect your home. However, shingles can blister as a result of several factors. Take note of these things to avoid costly repairs and early roof failure.

In this article, The Great American Roofing Company explains why asphalt shingles blister and what can be done to prevent or address the problem.

What Causes Asphalt Shingle Blistering

Trapped Moisture 

This sometimes happens during the manufacturing stage. Moisture gets trapped in the shingles during manufacturing, then bubbles up after being installed and exposed to the sun’s heat.

Improper Ventilation

A poorly ventilated attic traps heat, which then raises the roof temperature and accelerates the formation of blisters.

Poor Workmanship

Wrinkles, leaks and blisters on the roof can be due to incorrect installation. Poor workmanship can lead to different forms of damage and shorten the roof’s lifespan. To avoid this problem, make sure that you hire professionals for proper installation and regular inspection of your roofing system.

Extreme Heat 

Extremely high temperatures cause shingles to deteriorate more quickly. It also causes the blisters to rise and sometimes pop. When the blisters pop, shingle granules get dislodged, leaving the shingles exposed to the elements.

How to Prevent Shingle Blister From Popping

Trim Overgrown Trees

If you have trees near your home that continue to drop debris onto your roof, better trim them or remove them completely. Falling objects on your roofing system can cause blisters to pop. Addressing this problem right away will save your roof.

Don’t Walk on the Roof

When trying to inspect your roof for shingle blisters, avoid stepping on them. Blisters might pop even from little impacts and could inflict serious damage to the roof.

Address Attic Ventilation

If your attic has a ventilation issue, you should fix it right away to prevent heat buildup and high roof temperatures.
