The photos are from this mornings inspection, laminated shingles with spots of missing granules, while the spots may have been caused by hail there weren't any other signs present that I normally see when there has been hail, i.e. dents on the furnace vent cap, or other metal surfaces on the roof. Anyone else seeing irregular loss of granules on this type of roofing material?

I can't imagine that hail could take out chunks nearly that large. I would suspect a manufacturing defect.

Hail damage will commonly be on only one side of the roof due to prevailing wind at the time.

I've heard them called "tent blisters." They're the result of a manufacturing defect that causes the asphalt to blister up off the fiberglass backing. When the blister shears off, you're left with exposed asphalt as in your pictures.

The condition is considered cosmetic.

Usually caused by a bit of water in the mix during mfg.
