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.

Does a report mean my roof was damaged? No. A report says hail of that size was observed somewhere near that place. Only an inspection can show whether a particular roof was affected.
Where does this data come from? These figures come from preliminary storm reports compiled by the National Weather Service's Storm Prediction Center.
