Do you know which edition of the Florida Building Code your roof was permitted under? If you own a home in Florida, that one detail now decides whether a storm repair stays a repair or grows into a full replacement.
For years, Florida homeowners heard a simple version of the 25% rule: if more than a quarter of your roof is damaged, the whole thing has to come off. That said, a 2022 change in state law narrowed the rule considerably, and contractors, adjusters and neighbors still repeat both the old and new versions — sometimes in the same conversation.
This guide explains where the rule comes from, how the 2022 change applies to roofs built to the 2007 code and later, and what the change means for repair scope, permits and insurance claims.
What Is The Florida 25% Roof Rule?
The 25% rule lives in the Florida Building Code, Existing Building volume, within the reroofing provisions of Chapter 7. It limits how much of an existing roof can be repaired, replaced or recovered in any 12-month period before the entire roofing system or roof section must be brought up to the current code.
Under the traditional version of the rule, the threshold works in three parts:
- Below the threshold. Work covering less than a quarter of the roof within 12 months can generally be done as a repair, matched to the existing system, with the rest of the roof left alone.
- At or above the threshold. Once cumulative work reaches the 25% line, the code points to replacing the entire roofing system or roof section to current standards.
- Measured by roof or section. The percentage is calculated against the total roof area or an individual roof section, which is why your local building official's reading of what counts as a section matters.
Keep in mind that the 12-month window is cumulative. Two separate repairs of 15% each within a year can add up to a trigger, even if neither job looked large on its own.
Why Did Florida Change The Rule In 2022?
The rule began as a building-safety measure. An older roof patched piece by piece can end up with modern and outdated attachment methods side by side on the same deck, and hurricanes tend to find that kind of weak point.
Over time, however, the rule also became a lever in insurance claims. A modest wind claim could be argued into a full replacement on 25% grounds, and the cost of those replacements added to the broader pressure on Florida's property-insurance market.
In May 2022, the Legislature passed Senate Bill 4-D during a special session focused on condominium safety and property insurance. Among other changes, it amended Section 553.844 of the Florida Statutes and directed the Florida Building Commission to write an exception to the 25% rule for newer roofs.
How The 2022 Change Applies To Roofs Built To The 2007 Code
Under the amended statute, when 25% or more of a roofing system or roof section is repaired, replaced or recovered, only the portion being worked on must meet the current code. The condition is that the existing roof was built, repaired or replaced in compliance with the 2007 Florida Building Code or a later edition.
The undamaged rest of a qualifying roof can stay as it is. The Commission added the exception to the Existing Building volume, and your local building department applies it to the permit in front of them.
The 2007 Code Does Not Mean A 2007 Roof
This is the detail that trips up homeowners most often. The 2007 Florida Building Code did not take effect until March 1, 2009, so a roof installed in 2007 or 2008 was generally permitted under the earlier 2004 edition.
As a practical rule of thumb, a roof permitted on or after March 1, 2009 is the most likely to qualify for the exception. Roofs permitted before that date generally remain under the traditional 25% rule.
How To Confirm Which Code Your Roof Meets
It pays to establish your roof's code edition before a contractor or adjuster frames the scope. Useful sources include:
- The permit record. Most Florida counties and cities offer online permit search by address, so look for the reroof or new-construction permit and its application and final-inspection dates.
- Your purchase documents. A four-point or wind-mitigation inspection from your home purchase often lists the roof permit date and covering type.
- The final inspection. A permit that was opened but never finaled may not prove compliance, and building officials can treat it differently from a closed permit.
- Your policy file. Insurers also use roof permit dates for underwriting, so the same document does double duty.
All of these sources answer the same question: was the roof built, repaired or replaced in compliance with the 2007 code or later? If the answer is yes and the paperwork shows it, the exception should apply.
What The Change Means For Repair Scope
For a qualifying roof, the 2022 change moves the conversation from how much of the roof is damaged to which parts are damaged. A repair covering 30% or 40% of a post-2009 roof can now be scoped as a repair of that area, built to current code, rather than a tear-off of the whole system.
For an older roof, the scope math has not changed. Once cumulative work crosses the threshold within 12 months, the code still points to replacing the entire roofing system or roof section.
Here's how the paths typically compare:
- Pre-2009 roof, damage below 25%. The damaged area is repaired, and the rest of the roof stays.
- Pre-2009 roof, damage at or above 25%. The system or section is replaced to current code, including updated underlayment and deck-attachment requirements.
- Roof permitted under the 2007 code or later, any percentage. Only the repaired, replaced or recovered portion must meet current code.
Remember that the current-code requirement still applies to a partial repair on a newer roof. In practice, the new section gets current underlayment, fastening and flashing details even though the neighboring slopes do not.
Full Replacement Triggers More Than New Shingles
When a full replacement is required, the existing-building code adds requirements beyond the roof covering itself. For site-built single-family homes, those typically include a secondary water barrier or sealed roof deck, plus re-nailing the roof sheathing to current fastening schedules.
These items add real cost, which is why a full-replacement trigger matters so much financially. For a closer look at the deck work, see our explainers on sheathing nail patterns and roof decking replacement.
Permits And Inspections Under The New Rule
The exception does not do away with permits. Reroofing work in Florida generally requires a permit from the local building department, and the building official is the one who confirms whether the 2007-code exception applies to your property.
That makes your permit history a working document rather than old paperwork. Our guide to reroof permits and inspections walks through what inspectors look for at the dry-in and final stages.
Be aware that local rules matter, too. Miami-Dade and Broward counties sit in the High-Velocity Hurricane Zone, which has its own product-approval and installation requirements, and some jurisdictions define a roof section more narrowly than others.
What The Change Means For Insurance Claims
The 2022 change shifted the leverage in claims involving newer roofs. If your roof qualifies for the exception, an insurer can generally limit the claim to the damaged area plus a code-compliant repair of that area, and a 25% argument alone will not turn it into a full replacement.
For older roofs, the 25% rule still applies and can still require a full replacement when damage crosses the threshold. The question then becomes who pays for the undamaged portion that code requires you to replace.
Ordinance Or Law Coverage Fills The Gap
That cost usually falls under ordinance or law coverage, which pays for code-required upgrades beyond the cost of repairing the damage itself. Florida law requires insurers to offer this coverage on homeowners policies at limits of 25% or 50% of the dwelling limit, and you may have accepted or declined it when you bought the policy.
It makes sense to check your declarations page before a storm rather than after one. Our explainer on ordinance or law coverage covers how that limit is applied, and our guide to actual cash value vs. replacement cost explains how the base claim is valued.
Matching Is A Separate Question
A partial repair on a newer roof raises an obvious concern: will the new shingles match the old ones? The 2022 code change says nothing about appearance, and Florida's matching statute, Section 626.9744, separately governs whether an insurer must make replacements reasonably uniform in appearance.
In practice, a matching dispute can widen a claim's scope even when the 25% rule does not. Our post on roof matching disputes covers how those arguments typically play out.
Claim Deadlines Tightened In The Same Era
The broader reforms also shortened claim timelines. Under Senate Bill 2-A, passed in December 2022, notice of an initial or reopened property claim generally must be given within one year of the date of loss, and a supplemental claim within 18 months.
Note that your policy language controls the specifics. Our guide on how long you have to file a roof insurance claim covers the details, and our walkthrough on documenting storm damage helps you build the record either way.
Roof Age, Underwriting And The Exception
Roof age sits at the center of Florida underwriting, and the 25% exception connects to it. SB 4-D also barred insurers from refusing to write or renew a policy solely because a roof is less than 15 years old, and it gave owners of older roofs the right to an inspection showing at least five years of remaining useful life.
Keep in mind that the earliest 2007-code roofs are now more than 15 years old, so the code exception and the age protection no longer line up neatly. A roof can qualify for the partial-repair exception and still face age-based underwriting review, which our guide to roof-age nonrenewal explains.
Questions To Ask Before You Sign A Repair Or Replacement Contract
Whether your roof is older or newer, a clearly written scope protects you. Some useful questions include:
- Which code edition is my roof permitted under? Ask the contractor to cite the permit record rather than estimate from appearance.
- What percentage of the roof or section does this scope cover? Also ask whether the count includes other repairs made in the last 12 months.
- Which items are code-required, and which are optional? Ask the contractor to separate upgrades the code requires from upgrades they recommend.
- Who pulls the permit? In Florida, the licensed contractor typically pulls it, and it should be in place before work begins.
Overall, the answers should match your permit history and your policy. Our guide to replacement contract scope shows how those line items should read on paper.
If the answers do not line up, you may want to consider a second estimate. See how many roofing quotes you should get and how to verify a roofer is licensed and insured before you commit.
A Simple Decision Rule For Florida Homeowners
Start with the permit, not the damage. If your roof was permitted on or after March 1, 2009 and the permit was finaled, a large repair should generally stay a repair, with only the new work built to current code.
If your roof predates that, the traditional 25% rule still governs, and ordinance or law coverage becomes the deciding factor in what a full replacement costs you. For the wider picture, our guide on whether to repair or replace your roof walks through the factors that apply in any state.
