What does hail this size do to a roof?
Hail in this range is large enough to fracture or bruise asphalt shingles, dent metal, and crack tile; damage is commonly widespread where stones fell for more than a moment. Damage depends on more than size: wind-driven hail hits harder, older shingles are more brittle, and metal and tile fail in different ways. See our guides on hail damage and what to check after a storm for how to spot trouble from the ground.
