Radar sizes describe the storm over the ZIP, not any one roof. If a date above worries you, a local roofer can inspect for free, and your policy sets the deadline for reporting storm damage.

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.
