Hurricane damage is rarely fully visible on the day of the storm. Water intrusion conceals structural damage behind intact-looking walls. Roof damage that appears cosmetic reveals decking failure when the roofer starts work. Foundation issues appear weeks later as the soil dries. An initial adjuster estimate, conducted in the days after a storm, often misses damage that only becomes apparent during the repair process. That's what supplemental claims are for — and understanding how they work in Florida's post-2022 reform environment is essential for every property manager.

What a Supplemental Claim Is

A supplemental claim (or "supplement") is an additional claim for the same loss event, filed after an initial settlement has been reached. It is not a new claim — it relates to the same storm, the same property, and the same covered loss. The supplemental claim seeks additional payment for:

  • Hidden damage discovered during repairs: Structural damage behind a wall, rotted decking under shingles that appeared intact, water infiltration that caused damage to framing only visible after drywall removal
  • Contractor scope gaps: The initial adjuster estimate omitted covered items, used incorrect quantities, or priced components below current contractor rates
  • Material or labor price increases: In some cases where repairs are delayed, the cost to complete approved work increases above the settlement amount
  • Additional covered components identified after initial settlement: A component not noticed during the original inspection that is covered and damaged

Florida's 18-Month Supplement Deadline

Florida's 2022 insurance reform significantly changed the timeline for supplemental and reopened claims. Prior to 2022, the statute of limitations on first-party property claims was three years, giving policyholders ample time to discover and file for additional damage. Post-reform, supplemental and reopened claims must be filed within 18 months of the date of loss.

FLORIDA CLAIM TIMELINES — POST-2022 REFORM
First notice of loss1 year from date of loss
Supplemental / reopened claim18 months from date of loss
Prior first-party claim deadline3 years (eliminated by 2022 reform)
Clock startsDate of loss event (not settlement date)

The 18-month clock starts on the date of the loss event — typically the date the hurricane made landfall or caused damage to your property. It does not restart when you reach a settlement or when repairs begin. This means if a storm hit in June, your supplement window closes in December of the following year. Repairs that begin 6 months after the storm and take another 6 months leave only 6 months to identify and file any supplements.

18 MONTHS SOUNDS LIKE A LOT — IT ISN'T

In practice, the 18-month window compresses quickly. Initial claims take weeks to settle. Contractors are delayed due to post-storm demand. Repairs don't begin until 3–6 months after the storm. Hidden damage is discovered at month 9 or 10. By the time you identify supplement-worthy damage and obtain a contractor estimate, you may have only a few months left to file. Track the 18-month deadline from the date of loss for every hurricane claim and set a calendar reminder at 12 months to proactively review repair progress and identify any undiscovered damage before the window closes.

When Supplements Happen

The most common scenarios that generate supplemental claims:

Hidden Structural Damage

A roof that appears to have shingle damage reveals failed decking when the contractor starts removal. Wall sections appear intact until opened for a window replacement, revealing water-damaged framing. These discoveries are genuinely not visible at the time of the initial inspection — they're supplement-valid damage, not a contractor trying to inflate the claim.

Adjuster Scope Gaps

Post-storm adjusters are under significant volume pressure. Estimates frequently miss items: a section of soffit not included in the takeoff, a window that was documented as damaged but not included in the line items, HVAC damage not inspected. These are legitimate supplement grounds when you can document the discrepancy between the adjuster's estimate and the actual damage.

Contractor Estimate Exceeds Settlement

When contractor bids come in above the adjuster's estimate — which is common in high-demand post-storm markets — the gap is not automatically covered. You'll need documentation showing the actual contractor costs and a specific explanation of why the adjuster's estimate is insufficient. This is effectively a supplement negotiation, and it benefits from thorough documentation and, on larger gaps, public adjuster involvement.

How to Document Discovered Damage for a Supplement

The strength of a supplemental claim depends on your ability to establish two things: the damage is real, and it was caused by the original storm event (not pre-existing or caused during repairs).

  1. Photograph the damage immediately when discovered — during repairs, before any additional work is done to that area
  2. Get the contractor's written assessment — a written statement from the contractor describing what they found, where, and their professional conclusion that it resulted from storm damage
  3. Obtain a supplemental estimate — a separate written estimate for only the newly discovered damage, itemized by component
  4. Connect the damage to the original event — document why this damage was not visible during the original inspection (e.g., "damage was concealed behind structurally intact sheathing and only visible after removal during approved repair work")
  5. Notify your insurer in writing — contact your insurer referencing your original claim number, describe the discovered damage, and state that you are filing a supplemental claim
TIP: DON'T COVER DISCOVERED DAMAGE BEFORE DOCUMENTING IT

The most common mistake when hidden damage is discovered during repairs: the contractor immediately covers it up to keep the project moving. Once the damage is covered by new materials, your photographic evidence window is gone. Instruct contractors in advance to stop and notify you immediately if they discover damage that may not be covered in the existing estimate — before covering or repairing that area. A one-hour delay for documentation is worth far more than a disputed supplement with no photos.

The Insurer's Obligation to Respond

Once a supplemental claim is submitted, the same statutory timeline obligations apply as for the original claim:

  • The insurer must acknowledge the supplemental claim within 14 days of receipt
  • The insurer must pay, deny, or request additional information within 90 days
  • The insurer may send a re-inspector to assess the newly discovered damage — provide access promptly and have your documentation ready

If the insurer disputes the supplement, the policy's appraisal or mediation process may be available. For large disputed supplements, a public adjuster or attorney familiar with Florida insurance claims can help navigate the dispute process.

The Bottom Line

Supplemental claims are a legitimate and often necessary part of the hurricane claim process in Florida. Hidden damage, adjuster oversights, and contractor scope gaps are common enough that property managers should plan for the possibility of a supplement on any significant storm claim. The 18-month deadline means this planning must be active — track the clock from the date of loss, complete repairs as promptly as contractor availability allows, document discovered damage immediately and completely, and never let the window close without verifying there's no remaining uncovered damage.
