What ping-pong ball-size hail does to a roof
Hail in this range commonly bruises asphalt shingles and knocks off the protective granules. The roof may look fine from the street and still have lost years of life; soft metals like vents and gutters usually show the dents first. 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.
