What Causes Asphalt Shingle Blisters And How To Deal With Them
If you notice spots on your asphalt roof when you're cleaning the gutters, you might think your roof has hail damage you didn't know about. However, the real cause might be shingle blisters. Blisters can form on asphalt shingles for different reasons, and the damage is different from that caused by a hail strike. It's a good idea to let a roofing contractor examine your roof to determine what the spots are so repairs can be done if needed.
