A report is one point on a map

Each row above is one place where hail was measured. Hail swaths are a few miles wide, so a report across town does not prove hail fell on your street, and no report does not prove it did not.

Your roof, on radar

BeyondClaim reads the radar over your exact parcel boundary for this storm and every storm in 5+ years, and returns the peak hail size, the time, and a confidence score, traced to the scan it came from.

For roofers: the storm is the list

Storm maps shows this swath, Impact list names every roof under it with the hail size at each, and Door knock works the street house by house. Included in Pro and Team, no per-lead fee.
