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.

Where does this data come from? These figures come from preliminary storm reports compiled by the National Weather Service's Storm Prediction Center.

A place with no report may still have had hail, and a report does not mean any specific home was damaged. Places with more people tend to produce more reports.
