A blistering roofing system is a sign of trouble. Asphalt shingles are prone to blistering when they are exposed to extreme heat from the sun and the attic underneath is not ventilated well enough to dissipate some of this heat. When minute amounts of water trapped between the granule layer and the mat evaporate, they produce bubbles underneath the surface that eventually turn into visible blisters.

Blisters can lead to granulation loss and, if left unchecked, can cause your roof to fail, one shingle at a time. Luckily, blistering is a fairly easy problem to prevent. Here’s what you should do:

Don’t Pop the Blisters

If you see signs of blister formation on some of your asphalt shingles, take good care not to pop them. Avoid climbing on the roof and stepping on the affected areas as the pressure will be enough to cause them to rupture. This exposes the vulnerable matting underneath the shingle to harmful UV rays that could lead to worse issues. Call a roofing company right away to replace any blistered shingle as soon as you notice the problem.

Blistering vs. Hail Damage

Hail damage is a serious problem for any roof and can look similar to popped blisters on an asphalt shingle. However, hail damage will often be more uniform, affecting only one side of your roof slope depending on wind direction. Blisters are much more scattered. In fact, a roofing system affected by blisters will have a mix of popped and un-popped blisters spread across the surface.
