What tennis ball-size hail does to a roof
Hail this large routinely cracks and punctures asphalt shingles, dents metal vents and gutters, and can break skylights. Damage is often visible from the ground, but bruised shingles that look intact can still fail early. Radar describes the storm, not your shingles: the only way to know what a particular roof took is an inspection. Most homeowner policies set a deadline for reporting storm damage, so check your policy.
Every home inside a storm's radar footprint, scored by roof age, material and hail history, sold to a few roofers only so you are not the twentieth truck on the street.

Radar sizes are estimates from NEXRAD hail signatures (NOAA Severe Weather Data Inventory) for the largest stones in a storm cell, not a measurement at any one home. Ground reports are National Weather Service local storm reports and the NOAA Storm Events Database, as filed. Town-level data only; this page shows no addresses and no homeowner information.
