Proving Date of Loss with Weather Data

3 min read · updated July 2026 · MESHA Team

Who this is for

Public and independent adjusters working hail, wind, and storm claims, especially anyone who has heard "no event of record at the risk location" or "damage predates the policy period" and wants to never lose that argument again.

The problem

Date of loss disputes decide real money. When the carrier detaches the damage from the storm date, the claim slides toward wear and tear, prior loss, or no coverage at all. Most adjusters respond with adjectives and frustration. The adjusters who win respond with a layered file: public weather records pulled on day one, a property timeline proving the damage was not there before the date, physical evidence that agrees with the storm path, and one narrative page tying it together. None of that can be improvised after the denial letter arrives. It is a process, and it is learnable in an afternoon.
