One of the most common issues you may face with an asphalt shingle roof is blistering. It is often mistaken for hail damage, but there are a few key differences. Hail damage has much more uniform damage on a particular slope, for instance, while blistering asphalt shingles have parts of the rooftop that have unpopped blisters.
To help you determine the cause of asphalt shingle blisters and how to prevent them from occurring, read this article from Expert Contracting, one of the top roofing companies in the local area.
What Causes Shingles to Blister?
There are two main reasons why asphalt shingles blister: trapped moisture and inadequate ventilation. During the manufacturing process, moisture may get trapped within the shingle itself. As the trapped moisture begins to expand, especially during hot summer days, it can cause blisters to rise on the shingle.
Meanwhile, blister formation can also be accelerated by poor attic ventilation. Due to the intense heat, the temperature of the roof rises to the point where it can form blisters on the surfaces. Other roofing areas such as eaves may be affected by the trapped heat as well.
How Can You Prevent Shingles From Blistering?
While blisters on the shingles may not be a problem for the longevity of the roof, there may come a time that they will eventually pop. When they do, the granules will be dislodged, leaving the asphalt shingles unprotected from the sun’s UV rays. Since this can lead to leaks and roof damage, you may have to bring in a roof repair professional to fix the issue.
For this reason, it’s important to schedule regular roof inspections at least twice a year. During the inspection, a roofing expert will examine the condition of your roof and look for any signs of blistering. If you have poor ventilation, your roofer may recommend adding more vents to facilitate air circulation inside the attic. Without good ventilation, your roof may experience ice dam formation during winter or even potential structural damage from the trapped heat and moisture. To prevent blistering altogether, invest in high-quality asphalt shingles when you decide to have your current roof replaced. Hire a reputable contractor to make sure your new roof is properly installed.
