Did Hail Hit My House?

Enter your US street address in the search box above. HailScore searches NEXRAD radar, the NOAA Storm Events Database and CoCoRaHS volunteer observer reports within 8 miles of your property, and MRMS live radar within about 5 miles. The check itself is free, takes about 5 seconds and needs no account: you get the score, the interactive storm map plotting the most recent NOAA Storm Events hail reports within 8 miles, and a recent-hail panel stamped with the time its data was current as of. The event-by-event dated list unlocks with an email step.

Work backward from the record. Run the free address check, open the storm map, and read the nearby events: the date you want is usually the largest event that falls inside the lifetime of your current roof. If you already have a candidate day, the date check further down this page tests that exact day, or a window of one, three or seven days either side of it. Bear in mind the two halves of the record age differently — MRMS live radar is ingested every two hours, while the ground-verified NOAA Storm Events record for a recent storm publishes months later (typically 2-4), so a very recent date rests mainly on MRMS radar.

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.

Three NOAA datasets, plus one volunteer network. (1) NEXRAD Severe Weather Data Inventory — radar-estimated hail sizes from the National Weather Service's Doppler radar network, refreshed weekly. (2) MRMS MESH — Maximum Estimated Size of Hail, defined at https://www.myhailscore.com/mesh — ingested every two hours, so a storm usually appears in your report within about two hours. (3) NOAA Storm Events Database — National Weather Service official ground-verified reports (multi-month publication lag). And CoCoRaHS — the Community Collaborative Rain, Hail and Snow Network, a volunteer observer network that is not part of NOAA. Your report's Hail Event Log is labelled with the NOAA Storm Events Database as its source.

MESH is tuned so that roughly 75% of measured hail comes in at or below the radar estimate; read a size as a class (within about one tier), not as a measurement. What a size class does and does not tell you is spelled out at https://www.myhailscore.com/mesh. Separately, we search an 8-mile radius around your address so a cell that clipped your street still shows up even when its centre passed some distance away — that radius is a coverage choice, not an error bar on the size. For high-stakes use (an insurance claim), cross-reference the Storm Events ground-verified records that appear in your report: those are reports from spotters and other observers, not radar estimates.

Yes. The score, the storm map and the recent-hail panel are free with no signup; the dated event-by-event list unlocks with an email step. There's a paid $9.95 option — the Hail History Report at myhailscore.com/storm-report — if you need the history as a source-cited PDF document with an optional date-of-loss check, but the free check covers everything most homeowners need.

MRMS (live radar) is ingested every two hours, so storms that hit yesterday will appear in your report. NOAA Storm Events lags months behind (typically 2-4 months for the publisher's QC review). NEXRAD SWDI refreshes weekly. Every report's recent-hail panel is stamped with the time its MRMS radar data was current as of.

Enter your address and yesterday's date in the date check on this page. Overnight storms show up quickly: MRMS live radar is ingested every two hours, so a storm that hit after dark is normally searchable the next morning, while the ground-verified NOAA Storm Events record for that same night usually publishes two to four months later. One quirk worth knowing is that MRMS publishes a trailing 24-hour maximum, so a late-night storm can also surface on the following calendar day — hail showing on both days is usually one storm, not two. MESH is tuned so that roughly 75% of measured hail comes in at or below the radar estimate; read a size as a class (within about one tier), not as a measurement.

The honest answer is that records establish the neighborhood and only an inspection establishes the roof. Hail falls in streaks, so we run a radius search around your exact lat/lon rather than a ZIP or city lookup, and the report shows how far each event was from your property — a storm that passed 0.3 miles away is a very different fact from one that passed 7 miles away. What that gives you is exposure: hail of damage-capable size was recorded near your address on a given date. Whether it struck your particular slope, and whether it cracked or de-granulated anything, cannot be seen from radar or satellite. These are records of hail exposure, not of damage: size is a class, not a measurement, and a hail record near a property is not a finding that the property was 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.

Standard homeowner's insurance typically covers hail damage under the 'wind and hail' peril. Claim deadlines and coverage rules vary by carrier and policy — confirm yours with your insurer or, in Colorado, the Colorado Division of Insurance (doi.colorado.gov). The HailScore report shows the exact date(s) of the closest storms, which is what an adjuster needs to validate a claim.

Date of loss is insurance shorthand for the storm date that goes on a claim — the day the hail came through, not the day you noticed a problem. HailScore does not determine it, but it does narrow the candidates: run the free address check and read the dated events near your property inside your current roof's lifetime, and the event log is labelled with the NOAA Storm Events Database as its source. The date check on this page will then test a specific day, or a window either side of it, and report the largest hail size detected and how far away it was. Which date a carrier accepts is the carrier's decision, not ours. Claim deadlines and coverage rules vary by carrier and policy — confirm yours with your insurer or, in Colorado, the Colorado Division of Insurance (doi.colorado.gov).

Yes — use the date check on this page. Enter your address and any date back to 2010 and we search three NOAA hail datasets and the CoCoRaHS volunteer observer network within 5 miles of your property for that day (or a ±1/±3/±7-day window). You get a plain yes or no — or inconclusive, if one of the sources was unavailable, because a data failure must never read as a clean no — plus the largest hail size detected and its distance from your address, free. Note that ground-verified NOAA Storm Events records publish months after a storm (typically 2-4), so very recent dates rely mainly on MRMS radar, which is ingested every two hours.
