Frequently asked questions
How do I find out if hail hit my house?
Create a free account and run a Free Report Snapshot on your address. It answers YES/NO for estimated hail of 0.75 in. or larger and wind of 45 mph or more using radar-estimated hail, nearby station wind observations, official warnings, and ground storm reports — and shows you the records behind the answer.
Where does the data come from?
From the public weather record: NOAA radar hail estimates (MRMS), NOAA wind analyses (URMA/HRRR), NWS warnings and Local Storm Reports, official NCEI Storm Events, hurricane tracks, and FEMA declarations — updated daily. Values in reports are derived from these inputs using our published methodology. StormAuditor is independent and not a government service.
What does the free tier include?
A free account includes the at-address Free Report Snapshot (estimated hail ≥ 0.75 in. and wind ≥ 45 mph YES/NO), the Address Lookup with NWS warnings, storm reports, and NOAA station observations at your address, the statewide Impact Heatmap, the live Weather Stations map with NEXRAD radar, and the top five dates in the Date-of-Loss Database. The live radar with storm-day replay, the 7-day NWS forecast page, the storm data pages for all 50 states with free CSV/JSON downloads, the hail size and wind speed guides, and the storm recaps are open to everyone — no account needed. The full dated Weather Report with PDF export is $2.99 one-time for a single address, or from $4.99/month on a plan.
Are there free hail maps and wind maps?
Yes — the live radar map (50-minute live loop, storm-day replay back to 2012) and the 7-day NWS forecast page are free with no account at all, and free accounts add the statewide Impact Heatmap and the live Weather Stations map, plus open city and state hail and wind history pages covering all 50 states and free hail size and wind speed guides. The full Storm Calendar is included on Pro plans ($4.99/month), and the day-by-day statewide Hail Explorer and Wind Explorer swath maps, built from NOAA radar and analysis data, are included on Pro+ ($9.99/month).
Can I look up storm history by address for a past date?
Yes — the Address Lookup shows hail, wind, and storm history at any U.S. address, and the full Weather Report documents every qualifying storm date at the property with estimated hail size and peak wind gust per date. Storm recaps and the Date-of-Loss Database help you pin down which date to research.
Is StormAuditor built for roofers and public adjusters?
Yes. Roofing contractors, public adjusters, insurance adjusters, and claim attorneys use StormAuditor to find the date of loss, document estimated hail size and peak wind gust at each property, and show the evidence behind a date with the Audit Report. A single report is $2.99; the Organization plan covers five accounts with unlimited Weather Reports and Audit Reports for $29.99/month. Homeowners can run the Free Report Snapshot on their own address at no cost.
