What Was Florida's 25% Roof Rule?
For years, the Florida Building Code required that when 25% or more of a roof section was repaired, replaced or recovered within a 12-month period, the entire roof section had to be brought up to the current code. In practice, a storm that damaged a quarter of a roof could lead to a full replacement.
The rule was meant to stop older, weaker roofs from being patched piece by piece. But it also became a frequent point of dispute in insurance claims, since it could turn a partial repair into a much larger job.
What Changed in 2022?
In 2022, the Florida Legislature passed SB 4-D, which amended Florida Statutes §553.844. Under the change, 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% or more of it is being repaired, replaced or recovered, only the portion being worked on has to be built to the code currently in effect.
In other words, a newer roof that meets modern code can be partially repaired without forcing a full replacement, even when the damaged area is large.
Which Roofs Does the 25% Rule Still Affect?
The change protects roofs that already meet the 2007 Florida Building Code or later. Roofs built, repaired or replaced before that code took effect don't get the same protection, so a large repair on an older roof can still require bringing the whole roof section up to current code.
The quickest way to find out which category your roof falls into is its permit history. Your local building department, such as Sarasota County or the City of Sarasota, keeps permit records, and a roofing contractor can usually look up the most recent roofing permit for your address.
What Does This Mean After Storm Damage?
If a storm damages a large part of a newer roof, a repair limited to the damaged area may be all that's required by code. Your insurance policy is a separate question: what your insurer pays for depends on the policy terms and the damage, not just the building code.
If your roof is older, a large repair may trigger a full roof section upgrade, which affects both the scope of work and the cost. An inspection that documents the extent of the damage is the first step either way. See storm damage roofing for what to do after a storm.
Is Repair or Replacement the Better Choice Anyway?
Code is only one factor. Even when the law allows a partial repair, replacing an older roof can be the better long-term decision if the rest of it is near the end of its life. Our guide to roof repair vs. replacement walks through roof age, leak history, decking condition and cost.
What Else Did the 2022 Law Change?
SB 4-D also allowed insurers to offer a separate roof deductible on some residential policies. Whether your policy has one, and how large it is, is set out in your policy documents. Review them, or ask your agent, before you need to file a claim.
