Florida's 25% roofing rule: what homeowners need to know
Florida's 25% roof replacement rule, set out in Florida Building Code section 706.1.1, was written to protect property owners from structural vulnerability after storm damage. Understanding it matters, because it can turn what you assumed was a repair into a much larger job.
What the rule says
If more than 25% of a roof section is repaired, replaced or recovered within any 12-month period, the entire roof section must be brought up to current building code — unless the structure qualifies for an exemption. The 12-month window matters: several separate small repairs can add up across a year.
How Senate Bill 4-D changed things
Senate Bill 4-D introduced an exemption tied to when the roof was last replaced or permitted. Where a roof already meets the more recent code standard, the requirement to bring the whole section up to code does not bite in the same way. Whether your roof qualifies depends on its permit history.
Why it matters financially
The rule is where homeowners are most often surprised mid-project. A repair scoped as a small job can trigger a full section replacement, and if your policy does not carry Law and Ordinance coverage, the code-driven portion of that scope may not be covered.
Check before you start, not after
The permit history determines the answer, so establish it before work begins. We check it as part of the free inspection rather than discovering it once the roof is open.
