Roof Blistering: Can It Affect Your Retail Store?
If an outside contractor or another professional finds small dark spots all over your store's roof, you may wonder if the spots will cause problems for your store. If blisters caused the spots on your roof, it should concern you greatly. Roof blisters, or blistering, occur when air becomes trapped beneath your shingles and burst. The burst blisters can leave your roof and store open to water damage and other issues over time.
