After a storm damages part of a roof, one of the first questions Southwest Florida homeowners ask is whether they can repair just the damaged area or whether the whole roof has to be replaced. For years, the answer often came down to Florida's 25% roof rule.
That rule changed in 2022, and many homeowners in Naples, Fort Myers, Cape Coral and across Lee and Collier Counties still hear outdated versions of it. This guide explains what the 25% rule is, what changed, how to tell which version applies to your roof, and what it means when you're planning repairs.
Quick answer: Florida's 25% roof rule historically required that if more than 25% of a roof or roof section was repaired, replaced or recovered within a 12-month period, the entire roof or section had to be brought up to current building code. Since 2022, under Florida Statute 553.844, roofs built, repaired or replaced to the 2007 Florida Building Code or later only need the repaired, replaced or recovered portion built to current code, even when 25% or more is being worked on. Older roofs may still fall under the original rule.
This article is general information about the Florida Building Code and roofing, not legal or insurance advice. Your local building department makes final code determinations, and your insurer decides questions about your policy.
What Is the 25% Roof Rule in Florida?
The 25% roof rule is a provision of the Florida Building Code that governs repairs to existing roofs. In its original form, the rule said that no more than 25% of a roof's total area, or of a single roof section, could be repaired, replaced or recovered within any 12-month period unless the entire roofing system or roof section was replaced to meet current code.
The idea behind it was reasonable. Florida's building code has grown much stronger over the years, especially after major hurricanes. Patching a large portion of an older roof without updating it could leave a home with a roof that didn't meet modern wind-resistance standards.
In practice, though, the rule had a big effect on homeowners. A storm that damaged a third of a roof could trigger a requirement to replace the entire roof or section, which raised repair costs and complicated insurance claims.
What Changed With the 25% Rule in 2022?
In 2022, the Florida Legislature passed Senate Bill 4-D, which added a key exception to the 25% rule in Florida Statute 553.844.
Here's what the law now says, in plain terms:
- If an existing roof 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 repaired, replaced or recovered portion has to meet the current Florida Building Code.
- The Florida Building Commission must incorporate this exception into the Florida Building Code.
- Local governments can't adopt their own ordinances that change this exception.
In other words, for roofs built to the 2007 code or newer, the 25% threshold no longer automatically forces a full roof or section replacement. You can repair the damaged portion to current code without replacing the rest.
The reasoning is that roofs built under the 2007 code and later already meet much stronger wind standards than older roofs, so matching a repair to current code doesn't create the same safety gap.
Does the 25% Roof Rule Still Apply in Florida?
Yes, for older roofs. The 2022 exception only covers roofs or roof sections that were built, repaired or replaced in compliance with the 2007 Florida Building Code or later. If your roof was installed under an earlier code, the original 25% rule may still apply.
That means two neighboring homes in the same Naples or Fort Myers neighborhood can be treated very differently after the same storm, depending on when each roof was last replaced.
How Do I Know If My Roof Was Built to the 2007 Florida Building Code?
The 2007 Florida Building Code took effect on March 1, 2009. Roofs permitted on or after that date were generally installed under the 2007 code or a later edition. Roofs permitted before that date were generally installed under earlier codes.
To find out where your roof falls:
- Check the building permit records for your address. Collier County, Lee County and the cities within them keep searchable records of reroof permits, including the permit date.
- Look at your home purchase documents, seller's disclosure and prior inspection reports for the roof's installation date.
- Ask the roofing company that did the last full replacement for its records.
- Review any previous four-point or wind mitigation inspection, which often lists the roof's permit or installation year.
If records show your roof was replaced after March 1, 2009, it's likely covered by the 2022 exception. If your roof predates that, or the records are unclear, a roofer and your local building department can help you determine how the rule applies.
How Is 25% of a Roof Measured?
The rule looks at the percentage of a roof or roof section being repaired, replaced or recovered within a 12-month period. A few points help clarify how that works
- The calculation can apply to the total roof area or to an individual roof section, not just the roof as a whole.
- The Florida Building Code defines roof sections using features such as expansion joints, parapet walls and changes in roof type or elevation. Your roofer and building department determine how your roof is divided.
- The 12-month window means multiple smaller repairs can add up toward the threshold.
- According to a Florida Building Commission declaratory statement, only damaged components count toward the threshold, not the extra material needed to properly tie a repair into the undamaged roof.
Because the details depend on your roof's layout and history, it's worth having a roofer measure and document the damaged area before decisions are made.
What Does the 25% Rule Mean for Storm Damage Repairs?
After a hurricane or major storm, the 25% rule can shape the scope of the work your roof needs. Here are two hypothetical examples to show how it plays out.
Example One: A Newer Tile Roof in Naples
A tile roof on a Naples home was fully replaced and permitted in 2016. A storm cracks and dislodges tiles across about 30% of one roof section. Because the roof was installed under a code edition after the 2007 Florida Building Code, the 2022 exception applies. The damaged portion can be repaired to current code without replacing the entire section, assuming the rest of the roof is sound.
Example Two: An Older Shingle Roof in Fort Myers
A shingle roof on a Fort Myers home was installed in 2005, under an earlier code. Storm damage affects about 35% of one roof section. Because the roof predates the 2007 code, the original 25% rule may apply, which could require that entire roof section to be replaced and brought to current code.
These examples are simplified for illustration. Real roofs have unique layouts, histories and conditions, and the building department has the final word on code requirements.
What About Insurance?
The 25% rule is a building code requirement, not an insurance rule. How it affects a claim depends on your policy, including whether it includes law and ordinance coverage, which helps pay for costs required by building code. Your insurer and agent are the right sources for coverage questions. A roofer's role is to document the damage and explain what the code requires for the repair.

Do I Need a Permit to Repair My Roof in Southwest Florida?
In most cases, yes. Roof repairs and replacements in Florida generally require a permit from the local building department, whether you're in unincorporated Collier County, unincorporated Lee County or a city like Naples, Fort Myers, Cape Coral, Bonita Springs or Estero. Permit requirements vary by jurisdiction and scope of work, so check with your building department or ask your roofer, who typically pulls the permit as part of the job.
Permits also create the paper trail that helps determine your roof's age and code edition later, which matters for both the 25% rule and Florida's 15-year roof rule for insurance.
Should I Repair or Replace My Roof After Storm Damage?
The 25% rule is one factor, but it's not the only one. When we help Southwest Florida homeowners decide between repair and replacement, we look at:
- The roof's age and the code edition it was installed under.
- How much of the roof or each roof section is damaged.
- The condition of the underlayment and decking beneath the damaged area.
- Whether the roof has had recurring leaks.
- How the roof's age may affect your homeowners insurance.
- Your budget, and whether financing could help.
If repair makes sense, we'll recommend it. If the roof is near the end of its life anyway, replacing it may be the better long-term decision. Learn more about roof repair and roof replacement.

Frequently Asked Questions About Florida's 25% Roof Rule
Q: What is the 25 percent roof rule in Florida?
A: It's a Florida Building Code provision that historically required an entire roof or roof section to be brought up to current code when more than 25% of it was repaired, replaced or recovered within 12 months. Since 2022, roofs built to the 2007 Florida Building Code or later only need the repaired portion brought to current code.
Q: Does the 25 percent rule still apply in Florida?
A: It still applies to roofs installed before the 2007 Florida Building Code. For roofs built, repaired or replaced to the 2007 code or later, Florida Statute 553.844 allows only the repaired portion to be brought up to current code, even when 25% or more is involved.
Q: If 25 percent of my roof is damaged, do I need a new roof?
A: Not necessarily. If your roof was installed under the 2007 Florida Building Code or later, generally only the damaged portion has to meet current code. If your roof is older, the original 25% rule may require the whole roof section to be replaced. An inspection and your permit records will clarify which applies.
Q: When did the 2007 Florida Building Code take effect?
A: The 2007 Florida Building Code took effect on March 1, 2009. Roofs permitted on or after that date were generally installed under the 2007 code or a later edition.
Q: Can my city or county change the 25% rule exception?
A: No. Florida Statute 553.844 says local governments may not adopt ordinances that amend the 2022 exception for roofs built to the 2007 code or later.
Q: Does homeowners insurance pay for code upgrades under the 25% rule?
A: That depends on your policy, particularly whether it includes law and ordinance coverage. Your insurance agent or insurer can explain what your policy covers.
