Florida Building Code for Roofing: Which Edition Applies (2026)

The short answer (September 2026): Roofing work in Florida is permitted under the Florida Building Code, 8th Edition (2023), in effect since December 31, 2023. The Florida Building Commission has adopted a 9th Edition (2026) and lists its effective date as December 31, 2026. Ask your building department which edition will apply to your permit application.

This guide explains where the roofing rules sit in the code, what we could and could not confirm about the 9th Edition as of September 23, 2026, and what a homeowner or board planning a re-roof around the changeover should ask.

The edition in force today: 8th Edition (2023)

The Florida Building Commission’s website states: “The Effective Date for the Florida Building Code, 8th Edition (2023), is December 31, 2023” [1]. Miami-Dade County’s product control office gave the same date when it warned that HVHZ changes in that edition would affect some existing roofing underlayment approvals [5].

The Commission began work on the next edition, the 9th Edition (2026), in February 2024 and selected the 2024 International Codes as its starting point [2].

The workplan quotes the statute behind the timing: a rule updating the Florida Building Code “shall take effect no sooner than 6 months after publication of the updated code” [4].

What is still pending. The glitch amendments above were not final on September 23, 2026. We have not summarized the roofing changes in the 9th Edition as a whole, because we will not describe code text until the final version is posted and our team has read it. We will update this guide when it is.

One change reported in detail: coastal fasteners (Section 1711). The Florida Roofing and Sheet Metal Contractors Association (FRSA) and Engineering Express both describe a new Section 1711 in the 9th Edition that sets corrosion-resistance rules for fasteners and connectors within 3,000 feet of a saltwater coastline [10][11]. As they summarize Table 1711.1, stainless steel is generally required for exterior exposed or partially sheltered fasteners within 300 feet; enclosed fasteners, such as concealed tile fasteners, may use the galvanized option in Section 1711.1.1.2 [10][11]. Whether bays, brackish rivers and canals count as a “saltwater coastline” is not settled: FRSA reports a pending request for a declaratory statement [10], and the building official decides for a given property. Our salt or brackish water check measures the distance for an address.

Where the roofing rules sit in the code

The Florida Building Code is published in volumes. For roofs, three matter:

• Florida Building Code, Building, Chapter 15 — roof assemblies and rooftop structures. Sections 1512 through 1525 are the High-Velocity Hurricane Zone (HVHZ) roofing rules [7].
• Florida Building Code, Residential, Chapter 9 — roof assemblies in the Residential volume. Re-roofing must use the materials and methods of Chapter 15 of the Building volume or Chapter 9 of the Residential volume [8].
• Florida Building Code, Existing Building, Section 706 — reroofing: the 25% rule, when the old roof must be torn off, and structural capacity [8].

The HVHZ is Broward and Miami-Dade counties [7]. There, every roofing component must have “a valid and current product approval” [7]. Elsewhere, including Palm Beach, Martin, St. Lucie and Monroe, the general chapters apply unless the local jurisdiction has adopted the HVHZ provisions [7].

Rules that carry across editions

Some roofing rules do not reset when a new edition takes effect:

• The 2007-code exception to the 25% rule. Section 553.844(5), Florida Statutes, applies to roofs built, repaired or replaced under “the 2007 Florida Building Code, or any subsequent editions” [9]. A roof built to the 8th Edition will also count after the 9th Edition takes effect. See our guide to Florida’s 25% roof rule.
• The exception cannot be changed locally. A local government may not adopt an administrative or technical amendment to it [9].

What to ask if your re-roof falls near December 31, 2026

• Which edition will the building department apply to your permit application? Ask the department itself; do not rely on a salesperson.
• Are the product approvals in the proposal current for that edition? When the 8th Edition took effect, Miami-Dade noted that HVHZ changes affected some existing underlayment approvals [5]. Ask for the approval numbers, and ask the contractor to confirm them against the edition that will govern the permit. For tile roofs, Miami-Dade has posted a 9th Edition notice on underlayment [5]; our guide to the 2027 tile underlayment change explains it.
• Does the price change if the permit slips past the changeover? A proposal priced under one edition may need revisiting under another. Get the answer in writing.

Condominium boards planning a re-roof alongside a milestone inspection or SIRS should also read our condo milestone and SIRS guide.

Frequently asked questions

What is the current edition of the Florida Building Code? The 8th Edition (2023), in effect since December 31, 2023, according to the Florida Building Commission. It governs roofing permits until the 9th Edition takes effect.

When does the 9th Edition (2026) Florida Building Code take effect? The Florida Building Commission lists its effective date as December 31, 2026. Proposed glitch amendments were still open for public comment until October 8, 2026, so check the Commission’s website and your building department before relying on a detail.

Which edition applies to my re-roof permit? Ask your building department. It decides which edition applies to your permit application, and a contractor should confirm it before pricing the job.

Does a new code edition mean my existing roof has to be replaced? No. A new edition governs new work. When you repair or replace roofing, that work must meet the code in effect, and roofs built under the 2007 code or later benefit from the exception to the 25% rule in section 553.844(5).

Which Florida counties are in the High-Velocity Hurricane Zone? Broward and Miami-Dade. Roofing there follows Sections 1512 through 1525 of the Florida Building Code, Building, and every roofing component needs a valid and current product approval.

What roofing changes are in the 9th Edition? We have not published a full list yet. We will describe changes only after the final code text is posted and reviewed. One change is reported in detail by FRSA and Engineering Express: Section 1711 generally requires stainless steel for exposed fasteners within 300 feet of a saltwater coastline, with other corrosion-resistance rules out to 3,000 feet [10][11]. Your contractor and building department can tell you what applies to a specific permit.
