If your insurer says your hurricane damage was flood or storm surge rather than wind, it is invoking a policy exclusion, and under Florida law, the insurer carries the burden of proving that an exclusion applies to the damage it refuses to pay. A standard Florida homeowner’s policy covers windstorm damage. It excludes flood, a defined term that includes storm surge, meaning seawater pushed inland by a hurricane. When one storm brings both perils to the same property, the dispute is rarely all-or-nothing. It is a question of allocation: identifying which specific damage the wind caused and which the water caused, element by element, with evidence.
The deadlines come from statute. You must give your insurer notice of the claim within 1 year of the date of loss under Fla. Stat. 627.70132 (18 months for a supplemental claim), and you have 5 years from the date of loss to file suit for breach of the policy under Fla. Stat. 95.11(2)(e), after serving the pre-suit notice of intent required by Fla. Stat. 627.70152. One scope note before anything else: this page addresses disputes with your homeowner’s (wind) insurer. A claim under a National Flood Insurance Program (NFIP) policy runs on federal rules (including a one-year deadline to file suit after a written denial) and we address it separately on our flood insurance claim page.
Findings Summary
- A standard Florida homeowner’s policy covers wind and excludes flood. Storm surge is flood. Flood coverage exists only under a separate flood policy.
- The policyholder proves a direct physical loss occurred during the policy period; the insurer must prove an exclusion applies to the damage it will not pay.
- Florida appellate courts enforce anti-concurrent-causation clauses as written. The concurrent-causation doctrine of Sebo v. American Home Assurance Co. (Fla. 2016) applies only when a policy lacks that language.
- After Hurricane Helene, Florida insurers closed 46,656 residential claims without payment. Per the Office of Insurance Regulation (OIR), 20.3% of those closures cited the flood exclusion and 33.2% cited damage below the deductible.
- On February 20, 2025, OIR issued an Informational Memorandum warning insurers that improperly handled combined wind-and-water claims “will result in administrative action and restitution.”
- Deadlines: initial claim notice within 1 year of the date of loss (Fla. Stat. 627.70132); suit within 5 years of the date of loss (Fla. Stat. 95.11(2)(e)). Helene and Milton lawsuits remain timely into late 2029.
Why the wind-or-flood label decides who pays
A coastal Florida owner typically holds two separate contracts: a homeowner’s policy that covers windstorm and excludes flood, and, if purchased, a flood policy that covers rising water and nothing else. The same hurricane triggers both. Every dollar of damage gets assigned to one column or the other, and the assignment determines which policy pays, which deductible applies, and whether policy limits are adequate. On a surge-exposed home in Pinellas, Manatee, or Sarasota County, the allocation can swing the outcome by the entire value of the claim, because many flood policies carry limits far below the cost of the home.
| Damage | Policy that typically responds |
|---|---|
| Shingles, tile, or roof decking lifted or torn by wind | Homeowner’s (wind) |
| Rain entering through an opening the storm created | Homeowner’s (wind) |
| Ceilings and upper walls damaged by roof leaks | Homeowner’s (wind) |
| Rising water, storm surge, or tidal flooding at ground level | Flood policy (NFIP or private) |
| A horizontal water line, sand, or sediment on lower walls | Flood policy (NFIP or private) |
These are starting points, not rules. Every allocation turns on the facts of the specific building, and that is exactly where disputes arise. The 2024 season showed the pattern at scale: Helene pushed surge across the Gulf coast in September, Milton followed with a wind event two weeks later, and thousands of owners then received letters attributing wind damage to excluded water. OIR’s expanded denial-reason reporting, announced April 9, 2025, put numbers on it: of Helene’s 46,656 residential claims closed without payment, 20.3% cited flood exclusions and 33.2% cited damage below the deductible. If your denial rests on the deductible rather than the exclusion, our guide to the Florida hurricane deductible explains how that calculation works and where it goes wrong.
Who has to prove what
Florida law splits the burden of proof in a way that matters. Under an all-risk homeowner’s policy (the standard form), the policyholder’s initial burden is modest: show that a direct physical loss occurred during the policy period. Once that showing is made, the burden shifts to the insurer to prove that an exclusion applies. Flood is an exclusion. That means the carrier cannot deny your roof claim simply by observing that your neighborhood flooded. It must connect the excluded peril to the specific damage it refuses to pay, item by item.
This is the first thing we check in a flood-exclusion denial letter: does the carrier’s stated reasoning actually carry its burden, or does it wave at “storm surge in the area” while ignoring wind damage the surge never touched? A denial that fails to engage with the roof, the openings, and the upper-story water paths is a denial built on the wrong question. Our denied claim practice deals with exactly this pattern.
Anti-concurrent-causation clauses are enforced as written
Most Florida homeowner’s policies contain anti-concurrent-causation language: the flood exclusion applies “regardless of any other cause or event contributing concurrently or in any sequence to the loss.” In plain terms, if excluded water and covered wind combine to produce a single, indivisible item of damage, the exclusion controls that item. Florida’s district courts of appeal enforce this language as written, and the Florida Supreme Court has declined to review that enforcement. Assume your policy means what it says.
You may read elsewhere that Sebo v. American Home Assurance Co., 208 So. 3d 694 (Fla. 2016), guarantees coverage whenever wind is one of the causes. It does not. Sebo adopted the concurrent-causation doctrine (coverage where covered and excluded perils combine) for policies that lack anti-concurrent-causation language. The policy in Sebo had no such clause. If yours does, and most do, Sebo will not rescue an indivisible loss. Building a case on it is a common and avoidable error.
Enforcement runs both directions, though. The clause does not license carriers to stamp “flood” on everything within a mile of the water. On February 20, 2025, OIR issued an Informational Memorandum to all residential property insurers after learning of “potentially concerning behavior relating to anti-concurrent causation policy language and the explicit avoidance of applying coverage.” The memorandum requires combined wind-and-water determinations to be well documented and warns that improperly handled claims “will result in administrative action and restitution to the consumer.” The regulator’s message matches the legal reality: the clause reaches indivisible damage, not damage wind caused on its own.
The real fight is allocation, damage by damage
Because the clause is enforced as written, these cases are won by disaggregation, not doctrine. The question is never “was this a wind storm or a flood?” It is: what did the wind do to this building that the water did not? A hurricane damages a house in layers. Wind arrives first and works from the top down: roof covering, decking, flashing, soffits, windows, and then rain through every opening it created. Surge arrives later and works from the bottom up, and it stops at a measurable line. Damage above the water line, and damage that predates the water’s arrival, is wind damage the flood exclusion never reaches.
That framing converts a denial into a list. Roof system: wind. Wet insulation and stained ceilings under the roof breach: wind. Cabinets and drywall below a 30-inch surge line: flood. Flooring where roof water and surge both sat: contested, and argued on sequencing and physical evidence. A carrier that pays nothing because “the home flooded” has skipped this exercise. Our job is to force it, line by line, starting with the roof claim, usually the largest wind item and the one carriers most often fold into a flood denial.
The evidence that decides these cases
Wind-versus-flood allocation is an evidence contest. The record that wins it usually includes:
- Timing data. National Weather Service wind observations, tide-gauge records, and surge arrival times establish the sequence, wind before water, hour by hour for your location.
- The water line. Surge leaves a horizontal mark, sediment, and salt residue. Everything above it needs a different explanation, and the carrier has to supply one.
- Damage signatures. Uplifted decking, fastener withdrawal, directional debris, and wind-driven rain staining read differently from soak damage. We retain independent licensed engineers to analyze uplift and sequence the damage when the allocation is contested.
- Pre-storm condition records. Permit history, roof invoices, inspection reports, listing photos, and aerial imagery defeat the fallback argument that the roof was already failing.
- Your own documentation. Timestamped photos and video taken during and immediately after the storm are often the only direct evidence of when each kind of damage appeared.
Expect the carrier to send its own engineer, and read the resulting report skeptically: it is an opinion, not a verdict, and you are entitled to see the complete version. We wrote a separate guide on what it means when the insurance company sends an engineer to inspect your roof and how those reports get tested.
Watch the clock: yours and the insurer’s
Your deadlines: notice of the claim within 1 year of the date of loss and any supplemental claim within 18 months (Fla. Stat. 627.70132); suit within 5 years of the date of loss (Fla. Stat. 95.11(2)(e)). Worked example: for Milton, with a date of loss of October 9, 2024, the initial notice window closed in October 2025, but a lawsuit on a noticed claim remains timely until October 2029. Helene claims run to late September 2029. If you were underpaid in 2024 or 2025 and let the file go quiet, the courthouse door is still open. Run your own dates through our insurance claim deadline calculator, or see the full treatment in our hurricane claim deadline guide.
The insurer’s deadlines: under Fla. Stat. 627.70131, it must acknowledge your claim within 7 days, begin its investigation within 7 days of receiving your proof of loss, conduct any physical inspection within 30 days, and pay or deny the claim within 60 days of notice. Late payment accrues statutory interest. Our insurer response timeline checker compares your file against each requirement. Before any lawsuit, Fla. Stat. 627.70152 requires a written notice of intent to litigate at least 10 business days before filing, served through the Department of Financial Services portal. The mechanics of the suit itself (and the separate civil remedy notice path under Fla. Stat. 624.155, which after Fla. Stat. 624.1551 requires an adverse adjudication first) are covered in our guide to suing a homeowners insurance company in Florida.
Causation disputes are not only a hurricane problem
The same architecture (covered water versus excluded water, with the burden on the insurer) runs through non-storm claims all year. A sudden and accidental discharge from a burst supply line is covered; constant seepage over weeks is typically excluded, and carriers dispute which one your loss was. These fights are common: in OIR’s January 2026 Insurer Stability Unit report, water perils carry the highest litigation rates of any residential claim type: 11.68% for accidental discharge and 10.67% for other water damage. If your dispute is a pipe rather than a hurricane, start with our water damage claim page.
What it costs
Fee arrangements depend on the matter. Some wind-versus-flood disputes may be accepted on a contingency basis. Under a contingency agreement, no recovery means no attorney’s fee, case costs, or expenses are owed. The written agreement states the terms, including how engineering costs are handled, before any work begins. Fee exposure can also shift during litigation through proposals for settlement under Fla. Stat. 768.79, a tool that operates in both directions. For a fuller breakdown, see how much a property insurance lawyer costs.
How Cory Cannon approaches a flood-exclusion denial
I grew up around construction (my family has worked in the Florida construction trades for generations) and I read a carrier’s estimate the way a builder reads a scope: line by line, checking quantities, unit prices, and what was silently left out. In an allocation dispute, that means rebuilding the damage list from the structure itself, pricing the wind items against real bids from licensed local contractors rather than the carrier’s software, and retaining independent licensed engineers when sequencing is contested. Then we run the statutory sequence (demand, pre-suit notice, suit) on the timeline above. Start with our hurricane damage practice or request a free consultation; the review of your denial letter and estimate costs nothing.
One boundary worth naming: if your roof failed in winds well below what the building code required it to withstand, the problem may be the construction, not the storm: improper fastening, missing underlayment, bad flashing. That is a claim against the contractor or builder rather than the insurer, and it lives in our construction defects practice. I will tell you which side of that line your facts fall on, because pursuing the wrong defendant wastes your deadlines. For everything else in the policyholder toolkit, the property insurance claims hub is the place to start.
Frequently Asked Questions
Does homeowners insurance cover storm surge in Florida?
No. Storm surge is flood under standard policy definitions, and standard Florida homeowner's policies exclude flood. Surge damage is covered only if you carry a separate flood policy through the National Flood Insurance Program or a private flood carrier. Wind damage, including rain that enters through an opening the wind created, remains covered under the homeowner's policy. This is why a single hurricane routinely produces two claims under two different contracts for the same house.
Who has to prove whether wind or water caused my damage?
Under an all-risk homeowner's policy, you carry a modest initial burden: showing a direct physical loss occurred during the policy period. The burden then shifts to the insurer to prove an exclusion, such as flood, applies to the specific damage it refuses to pay. A carrier cannot meet that burden by noting flooding in your neighborhood; it must connect excluded water to each item of damage it denies.
What is an anti-concurrent-causation clause?
It is policy language stating that excluded perils such as flood are excluded "regardless of any other cause or event contributing concurrently or in any sequence to the loss." Florida appellate courts enforce these clauses as written, so when wind and surge combine to cause a single indivisible item of damage, the exclusion controls it. The concurrent-causation doctrine from Sebo v. American Home Assurance Co. helps only when a policy lacks this language. The practical response is allocation: proving what wind damaged on its own.
Can I still recover for my roof if storm surge flooded the first floor?
Yes. The flood exclusion reaches damage the water caused, not damage the wind caused independently. Surge stops at a measurable water line; a roof torn open by wind, and the interior damage from rain through that opening, sits entirely outside it. The claim is built element by element: wind items on the homeowner's policy, flood items on the flood policy, and contested items argued on sequencing and physical evidence.
How long do I have to challenge a flood-exclusion denial from Helene or Milton?
Five years from the date of loss to file suit for breach of the policy under Fla. Stat. 95.11(2)(e): late September 2029 for Helene, October 2029 for Milton. Separately, Fla. Stat. 627.70132 required initial claim notice within 1 year of the loss and allows supplemental claims within 18 months. If you gave timely notice and were denied or underpaid, the litigation window is still open, but Fla. Stat. 627.70152 requires a pre-suit notice of intent before filing.
Is a flood insurance claim dispute handled the same way?
No. NFIP claims are governed by federal law: a sworn proof of loss on FEMA's timeline, suit in federal court, and a hard one-year deadline to sue that runs from the insurer's written denial, not from the storm. Florida's state deadlines and pre-suit procedures do not apply. If your dispute is with your flood carrier rather than your wind carrier, treat it as a separate matter with its own clock.
The insurer's engineer concluded all my damage was flood. Is that final?
No. An engineer's report commissioned by the carrier is opinion evidence, not a ruling. You are entitled to the complete report, and its methodology can be tested: whether the engineer examined the roof, accounted for wind arriving before surge, measured the water line, or reviewed pre-storm condition records. We retain independent licensed engineers to answer carrier reports when the allocation is contested, and courts weigh both.
What if my wind and flood insurers each blame the other?
File and preserve both claims, on both sets of deadlines, and document everything before repairs begin. Each carrier must adjust the loss under its own policy; neither is excused because the other might owe something. In practice, allocation evidence (timing data, the water line, damage signatures) resolves the standoff, and litigation against the wind carrier remains available under the five-year statute in Fla. Stat. 95.11(2)(e) if it will not pay for what the wind did.
