Blistering shingles is a roofing condition that homeowners may experience within the first year of their asphalt shingles being installed. Blisters reduce the service life of asphalt shingles, and, if widespread, the entire roofing surface may need to be replaced sooner than expected. To help you fix and prevent the problem, it’s essential to know what causes it in the first place.
Manufacturing defects like poor asphalt mix and trapped moisture can cause bubble-like blisters to appear on the surface of shingles. These defects were particularly common in the past due to the manual mixing of shingle ingredients. Nowadays, manufacturers use automated equipment to prevent incorrect mixtures and blistering shingles. When replacing the roof, it’s important to hire roofing contractors who exercise strict partnership with reputable manufacturers.
Poorly Ventilated Roofs
If there is no adequate ventilation in the attic, the excessive heat can rise through the roofing deck until it reaches the asphalt shingles. This leads to blisters which will then compromise the appearance of shingles and speed up the deterioration process of your roof. This is why it’s important to observe regular maintenance to detect signs of poor attic ventilation like mold and ice dams.
How to Prevent Blisters from Popping
Popped blisters cause the granules on asphalt shingles to shift, leaving the roof unprotected from harmful ultraviolet (UV) rays. Rain water can also seep into the cracks and cause leaking roof problems. There’s only so much you can do to prevent blisters from popping, including minimizing foot traffic on the roof and cutting down overhanging tree branches. In the event of a hailstorm, you can’t protect your asphalt shingles anymore. This is why replacing your blistering shingles before they pop is the best way to protect your home from damages and costly repairs.
