Proving a hail date when nobody photographed the storm

Nobody photographs a storm they slept through, and damage discovered at a spring inspection may date to last summer. The reconstruction hierarchy that holds up: (1) official NWS records near the address — every recorded hail event in the candidate window, with sizes and distances; (2) corroborating local evidence — neighbor claims and reroofs from the same storm, contractor inspection dates, dated satellite/streetview imagery changes; (3) physical indicators — spatter marks, oxidation in dents — which support recency arguments but rarely pin a date alone.

In practice the official record usually narrows a vague "sometime in the last two years" to one or two candidate dates, and the corroboration picks between them. That narrowing is exactly what a per-address verification report automates.

Can the NWS record alone establish my date of loss?

It can establish that a documented hail event of a stated size occurred at a stated distance on a stated date — which is usually the decisive anchor. Whether that storm caused this damage remains an inspection question; the record cannot photograph your roof retroactively.

What if two storms could both have done it?

Document both events fully and let size, distance and direction argue: a 2.5-inch event half a mile away on date A versus a 1-inch event nine miles away on date B is not a coin flip. Where policies changed between dates, this distinction is the whole claim — put both rows in front of the adjuster.

Do carriers accept this kind of reconstruction?

Carriers' own weather vendors reconstruct exactly the same way from the same upstream records. Disagreements are usually about interpolation and modeling on top of the records, which is why citing the raw official rows — rather than a modeled swath image — keeps the conversation checkable.

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).
