Find the best date of loss for a roof claim

Enter the property address. The tool searches official NOAA / National Weather Service storm reports and nearby airport wind gauges, then recommends the single strongest date of loss to support wind or hail roof damage.

    Advanced: custom date window & coordinates

    Default window is the trailing 12 months from today. Use coordinates to override geocoding for a hard-to-match address.

    How the recommendation works: Each event is scored for roof-damage relevance — hail by stone size (≈1″ is the size commonly cited as capable of bruising/cracking asphalt shingles), wind by measured gust (≈50+ mph can lift or tear shingles; 58 mph is the NWS severe threshold), all weighted by distance from the property and reinforced when multiple reports cluster on the same day. The top date is the strongest single day to anchor a claim; always confirm it against independent radar imagery and the exact roof before relying on it.
