After flash flood damage, and before any repairs begin, these are the areas of a property most likely to have been affected:
- The exterior water line on the structure and how high water rose inside.
- Flooring, drywall, insulation, and baseboards for water intrusion and saturation.
- Mechanical systems that sat in water: HVAC, water heater, and electrical panels.
- Any structural movement, foundation scouring, or shifted footings.
See the first-24-hours guide for what to do before and while documenting this damage, and how reported flash flood measurements translate to property damage.
