Flood / Storm Surge
Rising surface water or ocean surge, excluded by standard homeowners policies and requiring separate NFIP flood coverage.
Last reviewed July 2026 against primary sources.
Key points
- Flood and storm surge are excluded by standard Florida homeowners policies.
- Coverage requires a separate flood policy, usually through the NFIP, which FEMA administers.
- Damage below the water line is generally a flood claim; roof and upper-floor wind damage is a homeowners claim.
- The wind-versus-water line is the central dispute in nearly every hurricane claim.
What it means
Flood and storm surge are two closely related water perils that a standard Florida homeowners policy does not cover. Flood is the rising or overflow of surface water onto normally dry land; storm surge is the wall of seawater that a hurricane's winds push ashore. Both involve water that arrives at ground level and rises, which is the distinction insurers draw against wind-driven rain that enters from above.
Because homeowners policies exclude flood and surge, coverage for that damage comes from a separate flood policy, most commonly through the National Flood Insurance Program (NFIP), which is administered by FEMA. Private flood policies also exist. Without one, ground-level rising-water damage from a storm is generally uninsured under the homeowners policy.
This term dominates hurricane claims because a single storm usually causes both covered and excluded damage at once: wind tears the roof, which the homeowners policy covers, while surge floods the ground floor, which only flood insurance covers. Which policy pays for what is decided by the source and height of the water, not by the fact that one storm caused all of it.
Separating the two is often the most valuable exercise on a coastal claim, because the homeowners carrier and the flood carrier each have an incentive to push damage toward the other policy.
In practice
When a home carries both a homeowners policy and flood coverage, each insurer tends to attribute damage to the other's peril to limit its own payment. Documenting the height of the water, the interior water line, the source, and the sequence of damage is what fixes the boundary between the two claims.
Damage above the surge or flood line, and virtually all roof and second-floor damage, belongs to the wind (homeowners) claim. Carriers sometimes blur this by writing the whole loss off as flood; a clear elevation and water-line survey restores the covered wind portion.
Real scenarios
Surge downstairs, wind upstairs
A coastal home takes 30 inches of storm surge on the ground floor while hurricane winds open the roof. The NFIP flood policy covers the ground-floor water damage below the surge line, and the homeowners policy covers the roof and the wind and wind-driven-rain damage on the second floor.
No flood policy in force
A homeowner without flood coverage suffers surge flooding. That rising-water damage is generally uninsured under the homeowners policy, but the wind-caused roof and interior damage above the water line is still a valid homeowners claim worth documenting separately.
Carrier blames everything on flood
A homeowners carrier denies a claim by attributing all damage to flood. An elevation and interior water-line survey shows the roof and upper-floor losses occurred above any flood level and were caused by wind, restoring the covered portion of the claim.

Flood / Storm Surge FAQs
No. Standard Florida homeowners policies exclude both flood and storm surge. That damage is covered only by a separate flood policy, most often through the National Flood Insurance Program, which is administered by FEMA.
Flood and surge are rising water that arrives at ground level; wind-driven rain enters from above through an opening that wind created. Wind-driven rain can be covered by a homeowners policy, while flood and surge are not.
By documenting the source and height of the water. Damage below the surge or flood line is a flood claim; wind and wind-driven-rain damage above it, including the roof, is a homeowners claim.
If you want coverage for rising-water and storm-surge damage, yes. It is not included in a homeowners policy and must be bought separately, commonly through the NFIP.
