Blistering is a type of shingle problems that affect asphalt shingles and manifests in the form of bubbles appearing on the surface of the shingles. Due to the evolution of the manufacturing process, shingle blistering was more common in the past, when the ingredients used for making the shingles were added by hand and manual process allowed for gases to penetrate the mix and the process creating the right material mix also used to be more difficult. Today, the manufacturing process is much more accurate, which still does not eliminate the possibility of having blisters on shingles, but makes the problem very rare.
The blistered on modern shingles are usually caused by excessive solar heat that overheats improperly ventilated roofing systems. Blisters become a serious issue when the blisters burst and rainwater penetrates through the tiny holes on the top pf the blisters into the deeper layers of the shingles. The sun heats up the tiny droplets of water inside the shingle, causing them to expand and to crack and break the affected shingle over time (usually a very short time).
The most obvious sign of shingle blistering is the appearance of small, circular spots where the surface granules are gone and the deeper layers of the shingle are visible. To determine if the roofing shingles on your home have developed blisters, it's best to have an inspection by one of the roofing companies Wichita KS has locally and resolve the issue if necessary.
