Evidence standards for supplements: adding weather records to an open claim

A supplement asks the carrier to pay for scope the original estimate missed. The estimate argues price; the weather record argues cause — that the newly documented damage is consistent with the same covered event. A supplement package that includes the official event citation (date, size, distance, narrative) preempts the "this is new/unrelated damage" pushback that otherwise stalls collateral-damage line items: gutters, window wraps, soft metals, fencing.

The standard is the same as the original claim: cite official rows with provenance and vintage, label preliminary data, and never let a modeled map stand in for the record it was modeled from.

Does a supplement need its own weather documentation?

It should reference the same documented event as the claim, with the citation attached rather than assumed — supplements are often reviewed by a different desk than the original claim, and self-contained packages move faster.

What weather evidence supports collateral line items?

The recorded size and the narrative. A 2-inch event narrative that mentions broken windows and dented vehicles in the area supports soft-metal and glass line items at this address; a 1-inch record argues a tighter scope. Match the asked scope to what the recorded storm class plausibly does.

The adjuster already accepted the storm date. Still attach the record?

Yes — acceptance lives in a file note you cannot see and may not survive reassignment. An attached citation costs a page and survives every handoff.

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).
