How HailScore answers the question
Four independent NOAA publishers. We query each one against your specific lat/lon and show you which sources confirmed the event.
5.9M+ records
NOAA Doppler radar-derived hail size estimates from 2015 to present, every storm ≥ 0.75 inch.
2.4M+ records
Maximum Expected Size of Hail, ingested every 4 hours so yesterday's storm shows up today.
299K+ records
NWS-verified ground reports — physically observed hailstones, the gold-standard validation layer.
25K+ records
Volunteer observer measurements from the Community Collaborative Rain, Hail and Snow Network.

What “hail hit my address” really means
When most people search “did hail hit my address,” they want one of three answers: (1) confirmation that a recent storm did pass over their property, (2) the date and size of past events so they can match them to a roof problem they just noticed, or (3) a defensible record for an insurance claim.
HailScore answers all three from the same lookup. The free report shows the storm map, the event timeline, and the closest verified hail event with its NOAA event ID — exactly the kind of source identifier an insurance adjuster can independently verify against the NWS database.
Hail of 1 inch or larger is generally capable of damaging asphalt shingles. Hail at 1.75 inches or larger is considered severe by the National Weather Service and often causes visible structural damage. If your report shows events at or above those thresholds within your roof's lifetime, scheduling a free local roof inspection is the standard next step.
Frequently asked questions
How do I find out if hail hit my house?+
Enter your US street address in the search box above. HailScore checks 8.6M+ NOAA-verified hail records (NEXRAD radar, MRMS real-time, NOAA Storm Events Database, and CoCoRaHS volunteer reports) within an 8-mile radius of your property and returns every documented event since 2015. The check is free, takes about 5 seconds, and doesn't require an account.
Can I check hail history for a specific address, not just a ZIP code?+
Yes. HailScore is address-level, not ZIP-level. Every lookup runs a geographic radius query against the NOAA NEXRAD radar grid centered on your exact street address. ZIP-only tools miss the fact that a single ZIP can span 50+ square miles — one half might have been hammered by a supercell while the other half saw nothing.
What NOAA data does HailScore use?+
Four publishers. (1) NEXRAD Severe Weather Data Inventory — radar-derived hail size estimates from the National Weather Service's Doppler radar network. (2) MRMS MESH — Maximum Expected Size of Hail, ingested in near-real-time (under 2-hour latency). (3) NOAA Storm Events Database — National Weather Service official ground-verified reports (60-90 day publication lag). (4) CoCoRaHS — volunteer observer measurements from the Community Collaborative Rain, Hail and Snow Network. We surface which publishers contributed to your report so you can verify independently.
How accurate is hail detection by address?+
Radar-derived hail size carries a ±0.25 inch margin compared to ground measurements, so we use an 8-mile search radius to capture storm cells that may have affected your street even if the storm centroid was nearby. For high-stakes use (an insurance claim), we recommend cross-referencing with the Storm Events ground-verified records that appear in your report — those are physically observed reports, not radar estimates.
Is the hail address check free?+
Yes. The score, the storm map, and the timeline of events are always free and require no signup or email. There's a paid $9.95 PDF report option if you need a date-of-loss-verified document for an insurance adjuster, but the free check covers everything most homeowners need.
How recent is the hail data?+
MRMS (live radar) updates every 4 hours, so storms that hit yesterday will appear in your report. NOAA Storm Events lags 60-90 days behind (the publisher's own QC window). NEXRAD SWDI refreshes weekly. We display a 'data current as of [date]' caveat on every report so you know exactly how fresh each source is.
Will HailScore tell me if my roof is damaged?+
No tool can confirm roof damage without a physical inspection — hail can crack shingles or knock granules off in ways invisible from satellite or radar. What HailScore tells you is whether your address was *exposed* to hail of damage-capable size (typically 1 inch or larger). If exposure looks real, your next step is a free in-person roof inspection from a licensed local contractor.
Does insurance cover hail damage?+
Standard homeowner's insurance typically covers hail damage under the 'wind and hail' peril. Most policies require you to file within 1-2 years of the storm date, though this varies by state and insurer. The HailScore report shows the exact date(s) of the closest storms, which is what an adjuster needs to validate a claim.
