Florida's 25% Roof Rule, Explained for Brevard Homeowners: When You Can Repair Instead of Replace

There is a single number that can decide whether a storm-damaged roof in Brevard County costs you a few thousand dollars or a full replacement. That number is 25 percent. Most homeowners hear about Florida's "25% roof rule" only after a contractor or adjuster uses it to justify tearing off the whole roof. By then you have lost your leverage. Here is how the rule actually works, the date that decides which side of it you fall on, and what to do before the next named storm crosses the coast.

What the 25% Rule Actually Says

The rule lives in the Florida Building Code. The plain version: if more than 25 percent of a roof is damaged or being repaired within any 12-month period, the entire roofing system has to be brought up to the current code. In practice that often means a full replacement, because you cannot patch a quarter of an old roof and leave the rest non-compliant.

That was the whole story for years. Then the legislature changed it.

The Exception That Changed the Math: SB 4-D

In May 2022, during a special session on the property insurance crisis, the legislature passed Senate Bill 4-D. It added subsection (5) to Florida Statute 553.844. The language matters, so here it is close to verbatim: if an existing roofing system or roof section was built, repaired, or replaced in compliance with the 2007 Florida Building Code or any later edition, and 25 percent or more of that system is being repaired or replaced, only the repaired or replaced portion has to meet the code currently in effect.

Translation: a qualifying roof can be repaired in part, even when the damage crosses 25 percent. You are no longer forced into a full replacement just because the damage is widespread.

One more detail with teeth. The statute bars local governments from adopting ordinances that amend this exception. So a Brevard County or municipal building department cannot quietly tighten it on you. The exception is the same in Rockledge as it is in Titusville or Melbourne.

The Date That Decides Everything: March 1, 2009

The exception turns on one cutoff. The 2007 Florida Building Code did not take effect until March 1, 2009. So the practical line is this:

If your roof was built or last replaced on or after March 1, 2009, and it was permitted to code, it almost certainly qualifies for partial repair. The 25 percent threshold does not force a full replacement on you.

If your roof predates March 1, 2009, you are still exposed to the old rule. Cross 25 percent damage and the full roof has to come up to current code.

A large share of Brevard's housing stock is older than that cutoff, especially in established neighborhoods in Cocoa, Titusville, and parts of Merritt Island. If you do not know the date of your last roof, that is the first thing to find out. Your permit history is on file with the county.

How This Plays Out on a Brevard Roof

Picture two identical homes on the same street after a wind event tears shingles off roughly a third of the roof.

House A was reroofed in 2016 under a pulled permit. It qualifies under the SB 4-D exception. The owner can repair the damaged third and leave the rest in place. Lower cost, faster turnaround, less disruption.

House B still has its original 2005 roof. Same damage, different rule. The 25 percent threshold triggers a full replacement to current code.

Same storm, same damage percentage, very different bills. The only variable that moved was the install date.

Why Insurers and Adjusters Care About the Number

The 25 percent line is also where insurance disputes start. An adjuster scoping a loss may argue the damage stays under 25 percent so the carrier owes only a repair. A contractor may argue it crosses 25 percent so the job becomes a replacement. On a pre-2009 roof, that argument decides whether you get a patch or a new roof. On a post-2009 roof, the exception changes the conversation entirely, because crossing 25 percent no longer forces a replacement by itself.

This is why the damage measurement is not a detail to leave to chance. Get your own qualified assessment of the damaged area and the roof's permit date before you accept anyone's characterization of the loss.

What Changes December 31, 2026

The code is moving again. The 9th Edition of the Florida Building Code takes effect December 31, 2026, and it revises how the 25 percent rule is applied, generally in the direction of allowing more partial repairs where the undamaged portion was built to the 2007 code or newer. The exact treatment is worth confirming with your roofer or the building department when the new edition lands, but the direction of travel is clear: the state keeps widening the path to repair rather than replace for code-compliant roofs.

For now, through the rest of 2026, the rule as described above is what governs your claim.

What Brevard Homeowners Should Do Now

Three moves, in order. First, find your roof's last permitted install or replacement date. That single fact tells you which version of the rule applies to you. Second, if you do not have a recent inspection, get one before storm season peaks, so you have a documented baseline of your roof's condition. Third, if a storm hits, get an independent damage assessment before you sign anything, because the 25 percent measurement drives the entire repair-versus-replace decision.

The 2026 Atlantic hurricane season is forecast by NOAA to be below normal, with 8 to 14 named storms expected, 3 to 6 of them hurricanes. Below normal is not zero. One landfalling storm on the Space Coast is all it takes, and the rule applies the same whether it is an average year or a quiet one.
