Evidence that matters
- Pre-loss photos or videos (exterior, roof, interior)
- Real-estate appraisal photos from when you bought
- Contractor invoices for recent improvements
- Building permits showing pre-loss condition
- Neighbor testimony / photos
- NOAA storm data confirming a weather event at the correct date
Independent investigation
A qualified inspector or engineer can often determine the age of damage from physical features (oxidation, staining patterns, materials).

What not to do
- Do not discard damaged materials before inspection
- Do not make permanent repairs before scope is agreed
