Roof Permits in Florida: Reroofing Rules and the 25% Rule

When a Florida roof replacement or repair needs a permit, how the 25% rule and the 2022 change work, reroof code upgrades, inspections and county differences.

Last updated: Checked against official sources: 3 min readBy the Florida Renovation Guide editorial teamTopic: Exterior Home Improvements

The short answer

  • A roof replacement needs a building permit and inspections in Florida, and the roofing must be done by a licensed roofing contractor or under one.
  • Florida's 25% rule says that if more than 25% of a roof or roof section is repaired or replaced in 12 months, the whole roof generally has to meet current code.
  • Since 2022, roofs built or replaced to the 2007 Florida Building Code or later are treated differently. Only the part being repaired has to meet current code.
  • Reroofs come with code upgrades, such as a secondary water barrier, and some higher-value homes near the coast need roof-to-wall connection upgrades.

In Florida, a roof is a permitted, inspected piece of hurricane protection, not just a weather cover. That's why roof permits come with more rules here than in most states, and why insurers care so much about the paperwork.

Does a roof replacement need a permit?

Yes. Replacing a roof requires a building permit, inspections during the job and a final inspection. The roofing itself must be done by a state-licensed roofing contractor. A general, building or residential contractor can run a larger project, but Florida law requires them to subcontract roofing unless they also hold a roofing license.

Small repairs are treated differently by different building departments, so ask yours whether a minor repair needs a permit. The 2026 small-project exemption can cover some owner repairs under $7,500 on request, outside flood hazard areas.

The 25% rule

The Florida Building Code's existing building provisions say that no more than 25% of the total roof area or roof section can be repaired, replaced or recovered in any 12-month period unless the entire roof or roof section is brought up to current code. The idea is to stop patchwork repairs from keeping weak, outdated roofs in place.

The 2022 change for newer roofs

A 2022 law (SB 4-D) added an important exception in section 553.844 of the Florida Statutes. If the existing roof was built, repaired or replaced under the 2007 Florida Building Code or later editions, and 25% or more of it is being repaired, replaced or recovered, only the part being worked on has to meet current code. The rest can stay as it is. Local governments can't amend that exception.

So the rule now works differently depending on your roof's age:

Your existing roofRepairing more than 25% of a roof section within 12 months
Built or replaced to the 2007 code or laterOnly the repaired portion must meet current code
Older than thatThe whole roof or roof section generally must meet current code

Some sources describe the 25% rule as "eliminated". It isn't; it still applies to older roofs. Your permit records show when the roof was last replaced.

Code upgrades at reroof time

A permitted reroof brings parts of the roof up to current wind standards:

  • Secondary water barrier. Florida requires one at reroof, such as self-adhering tape over the deck seams or a fully adhered underlayment, to limit water entry if the covering blows off.
  • Deck attachment. The roof deck's nailing must meet current requirements, which may mean re-nailing.
  • Roof-to-wall connections. In the wind-borne debris region, a site-built single-family home that wasn't permitted under the Florida Building Code (generally homes permitted before March 2002) and has an insured value (or, if uninsured, a just value) of $300,000 or more needs its roof-to-wall connections strengthened during a reroof, with gable-end bracing where needed. The requirement is limited by cost, measured against 15% of the reroof cost, so ask your roofer how it applies to your home.

These upgrades also feed into the insurance discounts a wind mitigation inspection can document.

Product approvals and the hurricane zone

Every roofing product must carry a Florida product approval or, in Miami-Dade and Broward (the High-Velocity Hurricane Zone), approval for that zone, usually a Miami-Dade Notice of Acceptance. See hurricane codes and product approval.

How roof rules differ by county

Roof replacement: how Florida counties compare
CountyWhat the published guidance says
Miami-Dade CountyA new roof needs a permit. Because the county is in the High-Velocity Hurricane Zone, roofing products must be approved for that zone, usually through a Miami-Dade Notice of Acceptance (NOA).
Broward CountyReroofs are on the county's list of work that needs a permit. As in Miami-Dade, roofing products must be approved for the High-Velocity Hurricane Zone.
Palm Beach CountyReroofing needs a permit. Ask PZB whether a minor roof repair needs one; the county publishes a list of work that doesn't.
Hillsborough CountyRoof replacement needs a permit. Apply through HillsGovHub, and confirm current requirements with Development Services.
Orange CountyReroofing needs a permit. Depending on the scope, related trade permits may also apply.
Jacksonville (Duval County)Re-roofing is treated as an alteration that needs a permit. Confirm current submittal requirements with the Building Inspection Division.
Pinellas CountyRoof replacement needs a residential roof permit through the county's online access portal.
Lee CountyRoof replacement needs a permit. The county has a separate guide for installing a new roof over an existing one, which is mostly used on manufactured homes.
Brevard CountyRepairing or replacing roof covering, including skylights, needs a county reroof permit. The county asks for a supplemental fastener affidavit, and a recorded Notice of Commencement on jobs over $5,000 must be approved before inspections can be scheduled.
Indian River CountyReroofing needs a permit. The county's roofing inspection guide calls for the approved permit documents and the product approval or Miami-Dade NOA to be on site at inspection, and lets roofing contractors, but not owner-builders, file a sheathing affidavit instead of a sheathing inspection. Confirm current forms with the Building Division.
Volusia CountyReroofs need a permit, applied for through Connect Live. The county's reroof inspections are sheathing (deck nailing), underlayment and final, with a roofing affidavit before the final. Since January 1, 2025, a reroof finished without inspections needs a site visit by the contractor and an architect or engineer to confirm it meets code.
Flagler CountyReroofs need a permit. The county's reroof packet asks for a roofing supplemental form, product approval numbers, a roofing affidavit and the roofing contractor's state license number.

Before you sign a roofing contract

Confirm the roofer's license, that the contract names the products and their approval numbers, that it lists the per-sheet decking price, and who records the Notice of Commencement. Read roof insurance claims in Florida first if insurance is involved or the roof was damaged in a storm; it also explains your right to cancel some roofing contracts.

Local permit guides

Who issues a roof permit, and how inspections run, depends on your county or city. We have local guides for Brevard County (Melbourne and Palm Bay), Indian River County (Vero Beach and Sebastian) and Volusia County (Daytona Beach and Ormond Beach), and county summaries on our local guides page.

Frequently asked questions

Can I repair part of my roof without replacing the whole thing?

Often, yes. Small repairs are common, and since 2022 roofs built to the 2007 code or later only need the repaired part to meet current code. For older roofs, repairing more than 25% of a roof section within 12 months generally means the whole section must meet current code. Your roofer and building department will tell you how it applies.

Do minor roof repairs need a permit?

It depends on the size and value. Some counties list small repairs below a dollar amount as exempt, and Florida's 2026 law exempts some owner projects under $7,500 on request. Larger repairs and replacements need a permit.

Can a general contractor replace my roof?

Florida law requires contractors to subcontract roofing work unless they hold a roofing license. A general, building or residential contractor can manage the project but must use a licensed roofing contractor for the roofing.

What inspections happen during a reroof?

Expect at least one inspection during the job, typically before the roof covering hides the deck nailing and underlayment, and a final inspection. Ask your roofer which inspections your building department schedules.
