Your flood damage and costs to repair/replace should be fully documented and described in detail in a complete Proof of Loss package submitted to the National Flood Insurance Program (NFIP)

Many people whose homes and businesses are damaged by flooding have a hard time getting accurate information about the true extent and cost of the damage to their properties.  Early estimates can be incomplete and often wrong. Qualified, reputable and affordable estimating help has been a challenge to find. Yet, a strong and persuasive proof of loss package is essential for reaching a full and fair settlement of an NFIP claim.   

If you are filing a supplemental Proof of Loss (that adds to or changes an earlier submitted version) your submitted package should includes copies of paperwork already submitted, plus updated estimates, reports and documentation before the Proof of Loss deadline.  We recommend getting the necessary package organized and submitted as soon as practical. 

If you need expert estimating or file review help but can't afford it, help is available. United Policyholders has been working with law schools and attorneys and claim experts sharing their professional skills at reduced rates as a community service toward the recovery effort.  

What “supporting documents” do we advise submitting to the NFIP?

We strongly advise submitting:

  • A line-by-line and room-by-room itemized report that details each building component that was damaged or destroyed, and sets a replacement/repair value for that item –including repair/replacement costs required to be incurred in order to comply with local building codes or construction ordinances.  The report should show unit prices, measurements, quantities and qualities.  Ideally it should be prepared by a local and experienced construction or repair cost estimating professional, a structural engineer (if appropriate) a building consultant or other qualified expert.  This report is often referred to as a “Scope of Loss” for more information.
  • Receipts, bills and invoices, and estimates of repair costs from contractors;
  • A report by a licensed engineer if there is any dispute about what caused the loss, such as when there is damage to a foundation or any structural issue that the insurer states is preexisting or caused by erosion, subsidence, or “earth movement,” or about whether the “basement” exclusion applies;
  • A report by any other independent and qualified expert that evaluated your damage.
  • Where possible, photographs from before the damage, with the damage and water line, and during or after repair; Be sure to keep copies of all photos and documents submitted.
  • For personal property, a room-by-room “contents list” attaching all of the available information above (photographs of the room or specific items if you have them, etc.), in addition to receipts for replacement or website printouts showing the same or near-identical item with a photograph and price; For help with your inventory, visit  For a sample home inventory, visit
  • Any additional documentation that you may have, including copies of earlier-submitted POL forms related to your loss and payment history.
