A flood claim goes to your NFIP or private flood carrier, not to your homeowners insurer — they are separate policies and a homeowners claim will be denied for flood water. Report it the day you find it. NFIP requires a signed Proof of Loss, normally within 60 days of the loss, and the documentation you gather in the first hours is what it is built from: video of every affected room before anything is moved, photographs of the high-water line, a list of damaged contents with what you paid, and receipts for emergency mitigation.
Mississippi homeowners should maintain both a standard HO policy and a separate NFIP or private flood policy; DeSoto County homeowners near Horn Lake Creek or Nonconnah Creek should verify their FEMA flood zone designation, as rapid suburban development has altered drainage patterns and expanded the effective floodplain beyond older FEMA maps. Mitigation is not optional — every policy requires you to stop further damage, so drying starts before the adjuster arrives, and you keep the invoices.
