Why Do Asphalt Shingles Blister?

Over time, your roof shingles will weaken due to extreme weather conditions, such as harsh summer heat and heavy hailstorms. Getting a roof replacement will be inevitable as blistering and swelling are likely to occur. In this post, we’ll delve into the reasons why blistering happens to asphalt shingles and discuss the ways of addressing it. 

Shingles Blister

Getting to Know Your Shingles

Asphalt shingles are made of three layers. Its backing material may either be made of recycled paper or fiberglass. The outermost layer is the granules with the roofing colors as well as other features like reflectivity and algae resistance. The asphalt is sandwiched between these layers. 

Due to manufacturing errors or improper installation by a roofing contractor, moisture can be trapped in between these layers. Once these shingles get exposed to heat, the moisture then expands and forms blisters.

Common Causes of Roof Blisters

As earlier stated, the common causes of roof blisters include moisture, insufficient ventilation and faulty installation. Blisters can form on an extremely hot roof surface, making poorly ventilated roofs prone to this particular dilemma. Once these are ignored, they can become bigger, allowing more moisture to penetrate the membrane, leading to costly fixes and replacement. 

Getting Rid of and Preventing Blisters

The best way to avoid and address this problem is to ensure your roof is installed correctly. You are always urged to hire a trained expert for this project. Rest assured, it pays to have your roof regularly inspected also.
