How to document the date of loss for a hail claim

The date of loss is the most consequential single field on a hail claim: it determines which policy (and which deductible) applies, whether the claim falls inside filing deadlines, and whether the carrier attributes damage to a covered storm or to wear and tear. Most homeowners discover hail damage weeks or months later — at a roof inspection, a sale, or a neighbor's reroof — so "when did it hail?" is usually answered by reconstruction, not memory.

The defensible way to reconstruct it is the official record. The NOAA/NCEI Storm Events Database holds every NWS-documented hail event back to 1950 with date, time, location, magnitude, and a narrative written by the local forecast office. For recent storms, the Storm Prediction Center publishes preliminary same-day reports. A claim file that says "hail of 1.75 inches was recorded 2.1 miles from the property on May 28" — with the event ID and a citation — replaces an argument with a lookup.

What documents establish a date of loss for hail?

The strongest documentary anchors are official weather records: NCEI Storm Events entries (the official NWS record), SPC preliminary storm reports for recent dates, and certified copies of either from NCEI. Photos with timestamps, roofer inspection reports, and neighbor claims from the same storm corroborate but do not substitute for the official record.

What if there were several hailstorms before the damage was found?

List every recorded hail event near the address across the relevant period — that is exactly what a per-address verification report compiles. The adjuster and policyholder can then reason from sizes, distances, and dates (e.g., the only ≥1-inch event in the period) instead of asserting a date from memory.

Does a recorded hail event near the address prove the damage happened that day?

No. NWS records are point and path observations: they document that hail of a given size was observed at a place and time. Attribution of specific damage to a specific storm combines that record with a physical inspection. The record narrows and anchors the question; it does not close it by itself.

Sources and standing caveat

Official records referenced throughout: NCEI Storm Events Database (the official NWS storm record, 1950–present) and SPC daily storm reports (preliminary, same-day). NWS records are point and path observations. The absence of a nearby report does NOT prove that no hail fell at this address — it means no observation was logged nearby. A report of nearby hail documents the event; it does not by itself prove damage to a specific structure. Nothing on this page is legal, insurance, or public-adjusting advice — deadlines, coverage and remedies are policy- and state-specific.

Put the record in the file

A per-address verification report compiles every NWS-recorded hail and wind event within 1, 3 and 10 miles of any US address — distances, official narratives, citations, provenance labels — formatted as an insurance-appeal attachment, hosted on HailEvidence (the neutral evidence surface).
