What the policy says
Section VII.G of the SFIP Dwelling Form (44 CFR Part 61, Appendix A(1)) lists what you must do after a flood loss. Item 4 requires that, within 60 days after the loss, you send the insurer a proof of loss, "your statement of the amount you are claiming under the policy signed and sworn to by you." The same section lists what the proof of loss must furnish, including:
- The date and time of loss.
- A brief explanation of how the loss happened.
- Your interest in the property (for example, owner) and the interest of anyone else, such as a mortgage company.
- Details of any other insurance that may cover the loss.
- Changes in title or occupancy of the property during the policy term.
- Specifications of damaged buildings and detailed repair estimates.
- Names of mortgagees or anyone else with a lien, charge or claim against the property.
- Details about who occupied the building at the time of loss and for what purpose.
- The inventory of damaged personal property described in item 3 of the same section.
Item 3 requires an inventory of damaged property showing the quantity, description, actual cash value and amount of loss, with bills, receipts and related documents attached.
Counting the flood proof of loss deadline
The 60 days run from the date of loss, which is the date the flood damaged the property, not the date of the adjuster's visit, the date you received an estimate, or the date of any denial. For a hurricane that flooded your home on a given day, count 60 calendar days from that day.
The interactive calculator on the home page shows the standard dates for your loss date.
The adjuster's report as a substitute
The SFIP's loss payment clause (Section VII.J.1) says loss is payable 60 days after the insurer receives your proof of loss, "or within 90 days after the insurance adjuster files the adjuster's report signed and sworn to by you in lieu of a proof of loss." Section VII.G.9 explains that the insurer may, at its option, accept the adjuster's report instead of your proof of loss; you must sign that report, and the insurer may require you to swear to it. Section VII.G.7 adds that the adjuster may furnish a proof of loss form and help you complete it, but only as a courtesy, and that you must still send a proof of loss within 60 days even if the adjuster does not. Section VII.G.8 says the adjuster is not authorized to approve or disapprove claims.
The practical problem is that a report the adjuster prepares states the adjuster's numbers. If you sign it as your proof of loss and later want more, you are generally limited to an amended or supplemental proof of loss, which must also be timely.
Amended and supplemental proofs of loss
Section VII.J.2 says that if the insurer rejects your proof of loss in whole or in part, you may file an amended proof of loss "as long as it is filed within 60 days of the date of the loss." Hidden damage often appears later, when drywall comes off or a contractor opens the floor. If that happens after day 60, a supplemental claim can still be presented to the insurer with supporting documents, and insurers do pay supplemental amounts, but a court case over amounts never included in a timely proof of loss is much harder. A lawyer can advise on how courts in your district have treated late supplements.
FEMA extensions after major storms
FEMA can waive or extend the proof of loss period by written bulletin to insurers, and it often does after large hurricanes. Recent examples affecting Florida:
| Event | Bulletin | Proof of loss period |
|---|---|---|
| Hurricane Helene (2024) | FEMA bulletin and press release, 2024 | Extended from 60 to 120 days from the date of loss |
| Hurricane Milton (2024) | W-24013, then W-24019 (December 2024) | 120 days, then extended again to 180 days from the date of loss |
Extensions are event-specific. Do not assume one applies to your loss: ask the insurer in writing which deadline it is applying, and check the NFIP bulletin archive at FloodSmart's NFIP Services site. Extensions of the proof of loss period do not change the one-year suit deadline after a written denial.
How courts treat a late or missing proof of loss
Because NFIP claims are paid from the federal treasury, federal courts generally require strict compliance with the proof of loss condition. Several federal appellate courts, including the Eleventh Circuit, which covers Florida, have upheld judgments for insurers where no timely, sworn proof of loss supported the amount sued for. Arguments that the insurer knew about the loss, or that the adjuster said a form was unnecessary, have usually not been enough unless FEMA itself waived the requirement in writing. That is why the safest course is to file a signed, sworn proof of loss for the full amount you claim before the deadline, even if the number is an estimate you plan to refine.
A practical checklist for the proof of loss
- Use the NFIP proof of loss form. The insurer or adjuster can supply it. Fill in every field.
- Claim the full amount you believe is owed. Attach your contractor's estimate and the contents inventory.
- Justify your number, then sign and swear. Section VII.G.5 says you must use your own judgment on the amount of loss and justify it. The policy calls for a statement "signed and sworn to by you." Notarization is the common way to show the oath.
- Send it with proof of delivery. Certified mail, email with a read receipt plus mail, or the insurer's portal with a saved confirmation.
- Keep a full copy of what was sent, with all attachments, and the date.
Private flood policies are different
A private flood policy sets its own post-loss duties. Many include a proof of loss clause, sometimes with a 60-day trigger after the insurer's request rather than after the loss. Florida's notice-of-claim statute, section 627.70132, generally requires notice of a property insurance claim within one year after the date of loss, and a supplemental claim within 18 months. See the private flood insurance guide.
If your NFIP claim has already been denied for a late proof of loss, read NFIP claim denied and consider a free case review. The Lawgical Firm, P.A. handles Florida property insurance claims; ask whether your flood claim is one the firm can take on.
Frequently asked questions
Is the flood proof of loss deadline 60 days from the loss or from the denial?
From the loss. SFIP Section VII.G.4 requires the proof of loss within 60 days after the loss. The 60-day FEMA appeal window, a different deadline, runs from the denial letter.
Does the adjuster file the proof of loss for me?
The adjuster may provide the form and help as a courtesy, and the policy allows a signed and sworn adjuster's report to be used in place of a proof of loss. But the duty to submit a timely proof of loss is yours, and the amount on it is what you will be held to.
Can I file a second proof of loss later?
An amended proof of loss must be filed within 60 days of the date of loss under Section VII.J.2, unless FEMA has extended the period for your event. Supplemental requests after that point may still be reviewed by the insurer, but they carry more legal risk.
Does a FEMA extension also extend the lawsuit deadline?
No. Proof of loss extensions address the proof of loss period. The suit deadline is one year after the insurer's written denial under SFIP Section VII.O and 42 U.S.C. 4072.
