What property owners should inspect
The exterior water line is the single most useful piece of documentation in a flash flood claim — photograph it before any cleanup, on every side of the structure it is visible on, since it establishes how high water rose and helps characterize how the water entered.
Because flash flood water recedes quickly, materials that were saturated can dry and look less damaged within days. Document flooring, drywall, and baseboards while they are still visibly wet or stained, and before any mitigation work begins.
- 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.
What to do in the first 24 hours
- Do not re-enter until local authorities confirm the structure is safe.
- Document everything before any cleanup begins — photograph and video the exterior, each affected room, and the full extent of the damage.
- Keep damaged materials and contents where it is safe to do so until they can be inspected.
- Keep receipts for any emergency mitigation work (pumping, drying, tarping, board-up).
- Contact your insurance company to report the loss, and write down the claim number and every adjuster's name and contact information.
How Unified Public Advocacy can help
Unified Public Advocacy is a 501(c)(3) non-profit public adjusting firm that represents property and business owners — not insurance companies. When a claim is disputed, underpaid, or built from a single insurer inspection, Unified Public Advocacy independently documents the loss, reads the policy, and re-presents the claim with the evidence to support it.
Unified Public Advocacy never takes a penny out of a property or business owner's pocket — the fee is covered by the overhead and profit built into the insurance settlement itself. If your property sustained damage in this event, you can reach Unified Public Advocacy at 1-855-944-3473.
From that first conversation through negotiating with the insurance company, Unified Public Advocacy's public adjusters handle the claim process directly, so you are not managing it alone on top of repairing or replacing what was damaged.
