Florida's 25% Roof Rule After SB 4-D: What Actually Changed

Florida's 25% rule says that if more than 25% of a roof section is repaired, replaced, or recovered within any 12-month period, the entire section must be brought up to current building code. Since SB 4-D passed in May 2022, there is a major exception: roofs built or permitted under the 2007 Florida Building Code or a later edition — in force since March 1, 2009 — may be repaired instead of replaced, as long as the repaired portion meets today's code.

We've explained this rule across a lot of kitchen tables in Clermont, Orange City, and Bradenton, and the short version is this: your roof's permit date is now worth real money. The same storm damage that forces one neighbor into a full replacement can be a straightforward repair for the neighbor across the street. Here's the whole picture, with the actual code sections and real numbers.

What the 25% rule says now

Under the current rule, when 25% or more of a roof section is repaired, replaced, or recovered, only that portion must be built to current code — provided the roof was built, repaired, or replaced in compliance with the 2007 Florida Building Code or a later edition. Roofs older than that still face the full-replacement trigger.

The rule lives in two places. Section 553.844, Florida Statutes, is the state law that SB 4-D amended. Section 706.1.1 of the Florida Building Code, Existing Building volume, is where the code applies it when you pull a permit. Both now say the same thing.

A few terms matter. A "roof section" is a separated area of roof — the main house versus a porch or an addition, for example. The 25% is measured against that section, not always the whole roof. And the window is any 12-month period, not a calendar year. Two 15% repairs eight months apart add up to 30% in the code's eyes.

One thing has not changed: whatever portion you repair must be built to today's code — current fastening, current underlayment, materials with Florida product approvals. The exception spares the undamaged part of the roof. It doesn't lower the bar for the repair itself.

How the rule worked before 2022

Before SB 4-D, Section 706.1.1 of the Florida Building Code, Existing Building volume, was blunt: no more than 25% of any roof section could be repaired, replaced, or recovered within a 12-month period unless the entire section was replaced to current code. Cross the line by a single square and the whole section came off.

The logic wasn't crazy. Florida rewrote its building codes after Hurricane Andrew, and the state didn't want pre-code roofs patched indefinitely. If a roof got damaged badly enough, the code used that moment to force it up to modern wind standards.

The practical effect was something else. After a hailstorm or a windstorm, the difference between 24% damage and 26% damage was the difference between a repair bill and an entire roof. Older roofs hit that trigger constantly, and the cost of all those full replacements became one of the pressures on Florida's property market. That's part of what the Legislature was reacting to when it called a special session in May 2022.

SB 4-D came out of that session. Most people know it as the condo-inspection bill passed after the Surfside collapse — the roof provisions rode in the same piece of legislation.

What SB 4-D actually changed

SB 4-D, passed in a special legislative session in May 2022, amended Section 553.844, Florida Statutes. The building code can no longer require full replacement when 25% or more of a roof is repaired, so long as that roof was built, repaired, or replaced in compliance with the 2007 Florida Building Code or any later edition.

In plain terms: if your roof already meets a modern Florida code, the state trusts it. You can repair the damaged portion — even if that portion is 40% of the roof — and leave the sound portion alone. The repaired area still gets built to the code in force today.

The Florida Building Commission wrote that change into the code as an exception to Section 706.1.1, and it carried forward into the 8th Edition (2023) of the Florida Building Code, the edition in force now. One date to keep in view: the 9th Edition (2026) takes effect on December 31, 2026. Permits applied for and issued before then are generally reviewed under the 8th Edition, so if you are weighing a repair against a replacement this autumn, the edition your permit lands under is worth asking your building department about.

Why is 2007 the cutoff? The 2007 Florida Building Code tightened the things that make a roof survive wind: fastening schedules, underlayment and secondary water protection, and product approvals for high-wind zones. Roofs built to it are a different generation from what came before, and the Legislature drew the line there on purpose.

What didn't change matters just as much:

• Roofs permitted before March 1, 2009 still live under the old rule. Past 25% in 12 months, the section gets replaced to current code.
• The building official issuing your permit still makes the call, and the rest of the roof has to genuinely comply. A post-2009 roof with rotted decking or a botched earlier repair can still be required to come off.
• Nothing in SB 4-D forces anyone to repair. It removed a mandate; it didn't create one.

The March 1, 2009 dividing line

The 2007 Florida Building Code took effect on March 1, 2009. That date is now the dividing line. A roof permitted on or after it can usually be repaired past the 25% threshold; a roof permitted before it still falls under the old full-replacement rule. Everything starts with the permit date.

Here's the decision path we walk with homeowners:

Was the roof permitted (or built in compliance) on or after March 1, 2009?
|
+-- YES -> The roof falls under the 2007 Florida Building Code or later.
|   |
|   +-- Does the rest of the roof comply with code?
|       |
|       +-- YES -> Repair is allowed, even past 25%.
|       |          The repaired portion is built to current code.
|       |
|       +-- NO  -> Expect the building official to require more --
|                  possibly full replacement of the section.
|
+-- NO (permitted before March 1, 2009)
    |
    +-- Is the damage under 25% of the section within 12 months?
        |
        +-- YES -> Repair is allowed under the old rule too.
        |
        +-- NO  -> The entire roof section must be replaced
                   to current code. The old rule still applies.

One trap to avoid: the date that counts is when the roof itself was permitted, not when the house was built. A 1995 house that was re-roofed with a permit in 2015 is a 2015 roof for this rule. Plenty of homeowners qualify and don't know it.

Three worked examples with real numbers

Numbers make the rule concrete. Below are three hypothetical Central Florida roofs — not real jobs — showing how the permit date changes the outcome. For replacement context we use our published asphalt-shingle pricing: $3.25 per square foot of effective roof area, which is the measured roof area plus a 15% waste factor.

Two notes before the math. Effective roof area is not your home's living area — a 2,000-square-foot house often carries more roof than that once pitch, overhangs, and waste factor in. And this rate is asphalt shingle replacement only; tile and metal are priced separately after an inspection.

Hypothetical roof	Roof permit date	Storm damage	What the rule allows	Replacement context
2,000 eff. sq ft, Clermont	2016	~30% of the section	Repair the damaged portion to current code	$6,500
2,800 eff. sq ft, Orange City	2004	~30% within 12 months	Full section replacement to current code	$9,100
3,300 eff. sq ft, Bradenton	1998	~20% of the section	Repair allowed — damage is under 25%	$10,725

Example 1 — the 2016 re-roof in Clermont (hypothetical). Hail strips shingles across about 30% of a 2,000-effective-square-foot roof. Before 2022, this roof would have been replaced in full. Because it was permitted in 2016, a code-compliant repair of the damaged slopes is now legal. Knowing that full replacement would run $6,500 at our published rate (asphalt shingle, priced on effective roof area) tells you whether the repair quote in front of you actually makes sense.

Example 2 — the 2004 roof in Orange City (hypothetical). Wind damage hits roughly 30% of a 2,800-effective-square-foot roof. Permitted before March 1, 2009, this roof still sits under the old rule: the whole section comes off and gets rebuilt to current code. Here's what full replacement looks like at our published asphalt-shingle rate, priced on effective roof area: 2,800 × $3.25 = $9,100.

Example 3 — the 1998 roof in Bradenton (hypothetical). Damage touches about 20% of a 3,300-effective-square-foot roof. That's under the threshold, so repair is legal even on a pre-2009 roof. But legal and smart aren't the same thing. A 28-year-old shingle is at the end of its life, matching a discontinued product is difficult, and the next storm is coming. Full replacement prices at $10,725 — the same figure our instant estimator produces for a roof this size. Sometimes the honest advice is that repair money is better put toward that number.

How to find your roof's permit date

Your roof's permit date lives in county records. Most Florida building departments run online permit portals you can search by address, and county property appraiser sites often list roofing permits too. Wind mitigation reports and closing paperwork usually name the roof's permit year as well. Ten minutes of looking usually settles it.

Where we tell homeowners to check, in order:

• Your county's building department permit portal. Search your address and look for a "reroof" or "roofing" permit and its issue date.
• The county property appraiser's parcel page. Many list permit history or an effective year for the roof.
• A wind mitigation inspection report, if you've had one done for your carrier — it records the roof cover's permit date directly.
• Closing documents or seller disclosures from when you bought the house.
• A phone call to the building department. Staff will look up permit history for your address.

If the records are murky — common with older homes and unpermitted work — we pull permit history as part of our storm inspections and put the date in writing.

What this means for your carrier claim

The permit date now shapes what a carrier owes on a storm claim. A roof permitted on or after March 1, 2009 with 30% damage may be a legitimate repair. A roof permitted before that date with the same damage still requires full section replacement to code, and the claim scope should say so.

That cuts both ways, so it pays to know your date before an adjuster climbs your roof.

If your roof is pre-2009 and the damage crosses 25% within 12 months, a repair-only scope is scoping the job below what the Florida Building Code requires. Section 706.1.1 is the citation that belongs in that conversation. If your roof is post-2009, the reverse applies — the 25% argument alone no longer forces a full replacement, and a claim built on that expectation can come up short.

The same event-versus-wear line runs through the rest of the roof edge — soffit and fascia damage is judged the same way, and storm damage there is a different conversation from years of rot.

Repairs bring their own wrinkle: matching. If your shingle color or profile is discontinued, a patch can be impractical no matter what the code allows, and that's a documented condition worth raising with your provider.

Our storm scopes are written for exactly this conversation — measurements, photo documentation, permit history, and the specific code citations that apply. That's the package we bring to hail and storm repair work. For policy questions — deductibles, coverage terms — talk to your carrier; we'll handle the roof facts. And if you're vetting contractors after a storm, read our guide on how to hire a roofer in Florida first, because storm-chasing outfits love this rule.

Where to start

If a storm just hit or you're staring at a repair estimate, do two things: confirm your roof's permit date, and get an independent number for full replacement so you can compare honestly. Our free instant estimator satellite-measures your actual roof and shows a real range on screen — without waiting on an appointment.

From there, a proper inspection settles the rest: how much of the section is actually damaged, whether the remaining roof complies, and which path the building official will accept.
