What storm history does HailScore show for an address?
After you submit an address, HailScore returns a free report: a 0–100 exposure score, an interactive map, and a timeline of nearby hail events with size, date, and distance. The free check is the same product path as the homepage — built for homeowners, buyers, sellers, and anyone researching a Colorado property.
Looking for a yes/no on a single day? Use Did hail hit my address? for date-scoped checks. For the full Colorado season picture, see Colorado hail statistics.
Need the history as a document — for a file, a sale, or an adjuster conversation? The Official Hail History Report ($9.95 PDF) formats the same records with a government source ID on every event. It documents exposure, not damage.
Why address-level storm history beats ZIP or city averages
Front Range storms can hammer one neighborhood and spare the next. A ZIP-code tool averages that away. HailScore centers the search on the property's coordinates so “storm history of a property” means that roof's neighborhood, not the whole metro. That is the same reason city pages like Lakewood and Denver still send you to an address check.
Which government sources power the history?
Engines and adjusters recognize these publishers by name. HailScore is not affiliated with or endorsed by the U.S. government.
6.2M+
NOAA Doppler radar hail signatures (nx3hail), ≥0.75″, 2015–present.
17.2M+
Live multi-radar mesh estimates — sub-2hr latency after storms.
303K+
NWS-verified ground reports; gold-standard human confirmation layer.
25K+
Volunteer observer hail measurements from the national network.
Also: SPC local storm reports and NWS alert context. Full arsenal: /coverage.
How current is the data?
Data current as of 2026-07-14 for the public arsenal floor (23.8M+ total, including 6.2M+ NEXRAD). Live MRMS is refreshed on a short cycle so yesterday's Colorado supercell usually appears within hours. NOAA Storm Events lags 60–90 days because NWS quality-controls those reports.
Details: methodology and status.
Storm history vs damage diagnosis
Looking up storm history answers “what hail was documented near this property?” It does not answer “is this roof damaged?” Exposure and damage are different. After you pull a free HailScore, use how do I know if my roof has hail damage for next steps — including when a licensed inspection makes sense.

Frequently asked questions
How do I look up the storm history of a property?
Enter the street address into HailScore on myhailscore.com. The free tool returns documented hail events near that Colorado (or US) property from NOAA NEXRAD radar, live MRMS, the Storm Events Database, and related government sources, plus a 0–100 exposure score — no signup required.
Can I look up storm history by address, not just ZIP code?
Yes. HailScore is address-level. A single ZIP can span many square miles; one block can take large hail while another sees almost nothing. Address-centered radius search is why property-level history beats city or ZIP averages.
What data sources does HailScore use for storm history?
HailScore draws on 23.8M+ verified hail records across NOAA NEXRAD (6.2M+), live MRMS MESH (17.2M+), the NOAA Storm Events Database (303K+), CoCoRaHS (25K+), plus SPC local storm reports and NWS alert context. Publishers are named on the free report.
How current is the storm history for a Colorado property?
Data current as of 2026-07-14 for the committed arsenal floor. Live MRMS updates within hours of a storm. NOAA Storm Events ground-verified reports can lag 60–90 days for quality control. Every free report shows freshness context so you know what is live vs finalized.
Does storm history mean the roof is damaged?
No. Storm history and HailScore measure documented hail exposure near the address — not a physical roof inspection or an insurance claim decision. Use the free ledger to decide whether a licensed inspection makes sense.
Is looking up property storm history free?
Yes. The free HailScore report — score, map, and event timeline — requires no account and no credit card. If you need the history as a portable document, the Official Hail History Report ($9.95 at myhailscore.com/storm-report) formats the same records as a source-cited PDF; it never gates the free lookup.
