What's inside
Five tools, one address-level data engine.
Live MRMS radar
LiveHail the radar sees usually reaches your report within about two hours. NCEP MESH_Max_1440min is ingested every two hours and indexed by location for fast lookups near an address.
Engineered hail swath maps
Team/FirmColor-ramped polygons by max hail size, the visual adjusters expect. Combines MRMS live data with 10+ years of SWDI NEXRAD radar. The canvass swath is a paid desk view (Team or Firm) — a free report shows an address-level event map with events plotted around the property, not the swath.
Source-cited PDF reports
LiveA storm-history PDF with a source citation on every event (NOAA Storm Events and NEXRAD record IDs). PDFs you make from your dashboard carry your company name. One report is $9.95; Team and Firm include a monthly quota.
Bulk address lookup
LiveUpload a list of addresses — up to 10 at a time on a self-serve account or a Team/Firm plan — and get a CSV back with scores, max hail, last event date and claim-window status. Built for canvassing teams.
API on request
On requestA REST API with per-key authentication, rate limits, JSON responses and an OpenAPI spec. Keys are issued per partner on request during the pilot — email hello@myhailscore.com. Your developer can wire it into your CRM or back office.
Date-of-Loss Verification
Anchor a storm date to the public weather record. Enter an address and a date of loss — HailScore searches NOAA Storm Events, NEXRAD SWDI radar, NCEP MRMS, and CoCoRaHS for hail of 0.75" or larger within 5 miles of the property across a ±45-day window, and returns every matching event with its original source record ID.
What you get back
- →A clear result — never a vague "verified": a qualifying event on the date of loss, the nearest qualifying event inside the ±45-day window, or no qualifying event found.
- →Every event cited to its source — NOAA Storm Events event number, NEXRAD station and cell ID, MRMS product and timestamp, CoCoRaHS station number — each traceable to its public source.
- →A PDF of the result with your company name on the cover (and your license number once a partner application is approved), ready for the adjuster file.
Honest about what it is
The report documents the storm record — whether hail of 0.75" or larger was recorded within 5 miles of the address in the window. (0.75" is this check's own floor; the National Weather Service's severe-hail threshold is 1".) It does not claim hail struck the roof; that finding belongs to your physical inspection. The two together — the cited weather record and your documented inspection — tell the full story. Determinations of coverage, causation, and payment rest with the carrier and adjuster.
Informational only — not legal, insurance, or tax advice.
How HailScore compares
Different products serve different jobs. We keep a sourced, dated comparison of what HailTrace, HailStrike, StormAuditor, Verisk Benchmark, Cotality and others publish about themselves, each statement linked to the company's own page.
See the sourced comparison →Built for
The pain: Canvassing teams chase outdated SWDI radar; sales reps knock with no storm record to show.
What you get: Pull live MRMS in the field and show homeowners the storm record for their address before you knock.
The pain: Carriers demand date-of-loss evidence; pulling SPC reports and stitching radar takes hours per claim.
What you get: One address, one PDF, every source cited. A one-off storm-history PDF is available at /storm-report — $9.95 per address.
The pain: Homeowners come to you weeks after the storm asking 'was I really hit?'
What you get: Address-level HailScore plus the paid swath view: two independent readings of what the radar recorded over that address. Exposure on record — only an on-roof inspection diagnoses damage.
The pain: Storm response is reactive — you find out a city got hit when the leads dry up.
What you get: Watch up to 25 saved addresses. During hail season (April–September), we email you when radar estimates hail of 1″ or larger within about 1.25 miles of one of them. Radar data usually reaches us within about two hours.
What you actually get, by trade
Same data engine, four very different workflows. Here's exactly what each role unlocks and the concrete pain it kills.
Know a listing's hail history before the buyer's inspector asks
The pain
A buyer's inspector flags hail damage you didn't see, and you're renegotiating mid-escrow.
What you actually get
- Score a batch of listings at once with bulk lookup — up to 10 addresses at a time on a self-serve account
- Route a cert request to a vetted licensed local roofer (Gates Enterprises in CO) — they perform and sign; the deliverable bundles their findings with our hail history
- Hail alerts on up to 25 saved listings during hail season, by email when radar estimates 1″ or larger within about 1.25 miles
- A storm-history PDF with the 10-year record and score for your listing presentation
Your buyer's questions about the roof's storm history get a dated, sourced answer.
Full walkthrough →Date-of-loss evidence in one source-cited PDF
The pain
Carriers want NOAA-cited evidence; stitching SPC and radar records together by hand takes time on every claim.
What you actually get
- A storm-history PDF per address, NOAA Storm Events and NEXRAD cited, ready for the claim file
- Date-of-loss check: was qualifying hail recorded near the address on the loss date, or within ±45 days?
- Loss Runs: verify up to 50 addresses per paste instead of one-at-a-time SPC searches
- Engineered hail-swath visualization adjusters already know how to read
Every event in the file carries its source record ID.
Full walkthrough →Add a storm-history page to every inspection report
The pain
Your competitor doesn't have it. You both inspect the same houses. One of you has a closing-edge differentiator.
What you actually get
- Pre-load tomorrow's inspections via bulk lookup the night before
- A storm-history PDF with your company name to add to the report
- Recorded hail of 1″ or larger near the address makes a closer roof look worth scheduling; the score shows exposure, not damage
Your client sees the hail events recorded near the address, each with its date, size, distance and source.
Full walkthrough →Pre-install hail exposure check — know warranty risk before you sign
The pain
Panel warranties exclude hail above certain sizes. You sign first, learn the property has a 2.5" history second.
What you actually get
- 10-year hail-size history at the exact install address (radar coverage 2015–today)
- Bulk-assess proposals before sales calls — kill bad-fit properties early
- Hail alerts on up to 25 saved installs during hail season, by email when radar estimates 1″ or larger nearby
- Engineered swath maps show where radar estimated large hail
See the hail record at the install address before you sign.
Full walkthrough →Source-cited storm evidence with raw government-record citations
The pain
Expert reports need storm data a reviewer can trace to a government record. Stitching NOAA, SPC and NEXRAD records together by hand costs hours per case.
What you actually get
- Source IDs on every event (NOAA Storm Events record, NEXRAD station) — anyone can check them against the public record
- Date-of-loss verification window (±45 days) framing the loss date you're litigating
- Black-letter PDF with a source-provenance footer
- Public methodology white paper at /methodology — disclosable to opposing counsel
Every event cited to its public source record.
Full walkthrough →Verifiable hail evidence at the property level, on the day of loss
The pain
Claims triage, SIU pattern detection, and renewal underwriting all need the same thing: an answer the carrier can stand behind. Stitching NOAA SED + MRMS + NWS + SPC together by hand is slow, repeated work.
What you actually get
- Property-level date-of-loss verification API cited to NOAA Storm Events, NEXRAD, MRMS and CoCoRaHS records
- Bulk-verify for in-force-book sweeps + renewal exposure scoring across the 11-year NEXRAD record
- Swath polygon vs. claim cluster geometry for SIU anomaly review
- Public methodology white paper (v7.1) at /methodology — disclosable to reinsurers and reviewers
90-day pilot at $15,000 fixed, fee waived if no measurable value is delivered against carrier-defined metrics.
