Came across this roof, there are raised dimples in a few different areas on the roof. They are not deteriorating and the aggregate is still in place. The roof is about 7 years old. The property is listed for $3.8M. How much of a concern should this be?
Blisters are a defect. They’ll probably pop. Problems in the production line. The makers almost never shut down the line, but try to pull off bad shingles before they get packaged. I’d recommend starting with the roofer that installed them. He could determine the manufacturer, then get the rep. involved. Good luck to the new owner.

Hi Linda- good question, I do not believe it is hail damage, but I am not sure. I would think there would be a dimple near the blister but I didn’t see any.
