It’s the question that decides whether a leak costs you hundreds or tens of thousands: can this roof be repaired, or does code force a full replacement? In Florida, the answer runs through what contractors call the 25% rule — and the rule changed in homeowners’ favor.

What the 25% rule says

Under the Florida Building Code, if more than 25% of a roof section is repaired or replaced within a 12-month period, that entire section historically had to be brought up to current code — which in practice meant full replacement of the section. One bad storm hitting a third of your roof could trigger a whole-roof bill.

The change that helps owners of newer roofs

Following 2022’s legislative reforms (SB 4-D), the Building Code carved out a major exception: if your existing roof was built or replaced in compliance with the 2007 Florida Building Code or later — roughly, permitted from March 2009 onward — then even damage beyond 25% can be repaired to match the existing roof rather than forcing full replacement. Only the damaged portion must be fixed, using compatible materials.

Translation: a 2012 tile roof with a wind-damaged slope can usually be repaired. A 1998 shingle roof with the same damage is still looking at replacement once repairs cross the 25% line.

How the math actually works

• The 25% is measured against the roof section, not always the whole roof — and how sections are defined can decide the outcome.
• All repairs within a rolling 12-month window count together. Two “small” repairs can add up past the line.
• Your local building department interprets and enforces the rule — documentation of your roof’s permit history is what makes the exception stick.

Why this matters for insurance claims

Adjusters and contractors argue over exactly this line every storm season. If your roof qualifies for the repair exception, a carrier may owe a repair, not a replacement — and if it doesn’t qualify, a “repair-only” settlement may not be enough to put your roof back legally. Knowing which side your roof is on before you sign anything is leverage.

Get a straight answer on your roof

SeaBreeze Roofing inspects the damage, pulls your roof’s permit history, and tells you plainly which side of the 25% line you’re on — then handles the repair or the replacement, permitted and inspected, as a State-Certified Roofing Contractor (CCC-1328689). And if you do end up with a new roof, don’t leave money on the table: a fresh wind mitigation inspection converts it into insurance credits.

Building code requirements are applied by your local building department and can change — always confirm how the rule applies to your specific roof and jurisdiction.
