Florida's 25% Roof Replacement Rule, Explained (2026)
Florida's "25% rule": if more than 25% of a roof section is repaired or replaced within 12 months, that work generally must bring the section up to current Florida Building Code. Since the 2022 reforms (SB 4-D), there's a big exception — roofs originally built or replaced under the 2007 code or later may be repaired to match, rather than fully replaced. Which side of the line you're on can be a five-figure difference after a storm. Leeward Roofing (CCC1337211) makes that call with you, documented.
How the Rule Plays Out After a Storm
Damage under 25% of a roof section: repair and match — no code-triggered full replacement.
Damage over 25%, roof built to 2007+ code: the 2022 exception usually lets you repair rather than replace the whole section.
Damage over 25%, older pre-2007 roof: current code likely requires bringing the entire section up to today's standard — often effectively a replacement.
Why This Matters for Your Insurance Claim
The repair-vs-replace decision drives claim value, and adjusters know this rule well. What matters is documentation: measured damage area, roof section boundaries, permit history and the code edition your roof was built under. We assemble exactly that package as part of our storm damage and insurance claim service.

Who decides if my damage crosses 25%?
Ultimately the local building official interprets the code, but the measurement and documentation your contractor submits carries the day. Get it measured properly before anyone puts a number in your claim file.
Does the rule apply per-roof or per-section?
Per roof section. A hip section over the garage can be evaluated separately from the main house — which is why precise measurement matters so much.
How do I know what code my roof was built under?
Permit records show when the roof was installed; 2007-or-later permits generally mean the repair exception applies. We pull permit history as part of every inspection.
Wind got under it? Do not wait for the next band.
Lifted shingles and displaced tile rarely reseal themselves. The cheapest version of this job is the one that happens before the next system comes through.
- Walk the perimeter and look for granules washed into the gutters and downspouts.
- Photograph soffit, fascia and gutter damage — adjusters ask for it.
- Tarp first, then worry about the permanent repair.
- Be wary of out-of-state crews that appear the day after a storm.

What the rule actually says
Florida Statute 553.844 and the Florida Building Code, in plain language, with the exception that changed everything in 2022.
The base rule
If more than 25% of a roof or roof section is repaired, replaced or recovered within any 12-month period, that roof section must be brought into compliance with current building code. On its face that reads like “a storm took a third of my shingles, so I am buying a whole roof.” That has not been the full picture since May 2022.
The 2007 exception — the part that matters most
Florida Statute 553.844(5), as amended by SB 4-D effective 27 May 2022, provides that if the existing roof system or roof section was built, repaired or replaced in compliance with the 2007 Florida Building Code or later, then only the repaired, replaced or recovered portion must meet current code. The undamaged remainder stays. For a home reroofed in, say, 2014, that usually means a legitimate partial repair rather than a forced full replacement.
If your roof predates 2007, the old rule applies in full
Cross 25% on a pre-2007 roof section and the entire section comes up to current code. On older housing stock — much of Fort Pierce, downtown Stuart, historic Vero Beach and the original GDC grids — that is frequently a genuine replacement. It should be because of the code and the condition, though, not because someone wanted the bigger job.
What changes at the end of 2026
The 9th Edition of the Florida Building Code takes effect 31 December 2026 and further widens the allowance for partial replacement where the remaining undamaged roof was built to 2007 standards or newer. We track these cycles because they change what we are permitted to quote you.
“Roof section” is not the same as “whole roof”
The rule applies per roof section, not necessarily to the entire structure. A detached garage, a separate wing or a distinct roof plane can be its own section. This matters, and it is frequently overlooked in scoping.
How it is actually enforced
Through the permit. Section 15 of the Indian River County and City of Vero Beach joint re-roof application requires a roof diagram on every roof permit, and for repairs it must show dimensions and square footage of the repaired area specifically so the building department can verify compliance with FBC Existing Section 706.1.1. That is the mechanism. If you have wondered how anyone polices the 25% rule, this is it.
How the rule gets misused
It is the most common pressure tactic in Florida roofing sales. Here is how to tell.
“Code requires a full replacement” — with no measurement
If nobody has measured and photographed the damaged area, nobody knows whether you are over 25%. The claim is an assertion, not a finding. Ask to see the number and the diagram.
No mention of the 2007 exception
A contractor invoking the 25% rule without asking when your roof was last replaced is either unaware of the exception or choosing not to raise it. Both are reasons for a second opinion.
Applied to the whole house
The rule works per roof section. Damage to one plane does not automatically pull in a detached garage or a separate wing.
Used to justify a claim scope
It cuts both ways — the rule is also legitimately used to establish that code upgrades belong in an insurance scope, which is fair. Ordinance and law coverage exists precisely for that. See our claim guide.
What we do instead
Measure the damaged area, photograph it, check the build or last-replacement date, and tell you which side of the line you are on before we write anything. If you are under it and your roof qualifies, we say so.
When the honest answer is replacement
Sometimes it genuinely is — a pre-2007 roof with damage well past a quarter of a section. We will show you the measurement rather than asserting the conclusion.
Florida 25% roof rule FAQs
What is the 25% rule in Florida roofing?
Florida Statute 553.844 and the Florida Building Code provide that if more than 25% of a roof or roof section is repaired, replaced or recovered within any 12-month period, that section must be brought into compliance with current code.
Does the 25% rule always mean a full roof replacement?
No, and this is the most misunderstood part. Since SB 4-D took effect on 27 May 2022, if the existing roof system was built, repaired or replaced in compliance with the 2007 Florida Building Code or later, only the damaged portion must meet current code. The undamaged remainder can stay.
My roof was replaced in 2015. Am I covered by the exception?
Almost certainly yes, provided it was permitted and built to the code in force at the time. That means crossing 25% should require only the damaged portion to comply rather than the whole section. Keep your permit close-out documentation - it is the evidence.
My house was built in 1998 and never reroofed. What happens?
The exception does not apply, so crossing 25% on that roof section triggers a full code upgrade for the section. On older housing stock this is frequently a genuine replacement - but it should be established by measurement, not asserted.
What counts as a roof section?
The rule applies per roof section rather than automatically to the entire structure. A detached garage, a separate wing or a distinct roof plane can be its own section. This is frequently overlooked when contractors scope work.
How does the county actually check?
Through the permit. Section 15 of the Indian River County and City of Vero Beach joint re-roof application requires a roof diagram on every roof permit, and for repairs it must show dimensions and square footage of the repaired area so the building department can verify compliance with FBC Existing Section 706.1.1.
Is the 25% rule changing?
Yes. The 9th Edition of the Florida Building Code takes effect 31 December 2026 and further widens the allowance for partial replacement where the remaining undamaged roof was built to 2007 standards or newer.
A contractor told me code forces a full replacement. Should I believe them?
Ask two questions: what is the measured square footage of the damaged area as a percentage of the section, and when was the roof last replaced. If they cannot answer both, the claim is an assertion rather than a finding. A free second inspection costs you nothing.
Does the rule affect my insurance claim?
It can help. Where code upgrades are genuinely triggered, those costs are legitimately part of the claim scope and ordinance and law coverage exists to pay for them. Carrier scopes frequently omit them.
Does the rule apply to commercial roofs?
The same Florida Building Code Existing Building provisions apply to commercial low-slope roofs, though section definitions and recover allowances differ. See TPO & commercial roofing.
