Blisters, or small circular raised areas, are often the direct result of under-ventilated attics or excessive use of plastic cement - both of which are installation errors.
If the blisters are closed and are not affecting the shingles' performance, they are not a cause for concern. But if the blisters are open, exposing the asphalt, the roof is vulnerable to water penetration and requires immediate attention.
Buckling, a distortion of the shingles, can be a possible sign of inadequate roof ventilation, issues with the roof deck or other installation errors and may require attention.
Deep cracks that penetrate through the fiberglass mat should be investigated, as they may compromise the roof's ability to shed water and make it susceptible to leaks.
