Florida's New Building Code Starts Dec. 31: What the 2026 Edition Changes for Your Roof

Every three years, Florida adopts a new edition of its statewide building code. The next one, the Florida Building Code, 9th Edition (2026), takes effect on December 31, 2026. If a new roof is somewhere in your plans, here's what changes, when it applies to your job, and what's worth asking your roofer.

This is general information, not legal or engineering advice. The summaries below come from the Florida Building Commission's published analyses of the 2026 changes. Your building department and the code itself have the final word.

When the new code applies to your roof

The 8th Edition (2023) has been in force since December 31, 2023, and it's still the code for permit applications today. Sarasota County's building page, for example, still lists the 2023 8th Edition as its current code.

Florida's long-standing rule is that the code in effect on the date a permit application is submitted governs that permitted work for the life of the permit. In practice, that means the date your roofer applies for the permit matters more than the date the crew shows up. Miami-Dade County's October 7 notice puts it plainly: permit applications and plans submitted on or after December 31 must comply with the new edition.

Each building department sets its own cutoff details, like how a late-evening online submission on December 30 is counted. If your job will be permitted in late December or early January, ask your roofer, or call Manatee County, Sarasota County, or your city's building department, which edition your application will fall under.

What changes for shingle roofs

Most single-family homes are covered by the Residential volume of the code. The Commission's analysis of the 2026 Residential changes lists several roofing updates:

• Hip and ridge shingles get their own wind rule. They must either be tested and classified under the UL 2375 wind test, modified to a 110 mph wind speed, with packaging labeled to show it, or be installed with a prescriptive method: two spots of roof cement at least 1 inch across on each side of the hip or ridge, near the leading edge and covered by the shingle, in addition to the manufacturer's required fasteners.
• Drip edge is fastened at 4 inches on center statewide. The shingle drip edge section now requires mechanical fastening at 4 inches on center throughout the state, with fasteners that meet the shingle fastener requirements.
• Underlayment laps over hips and ridges. Underlayment must lap over hips and ridges by at least 6 inches, except where ventilation openings are provided.
• Flashing rules are clarified. The flashing section was broadened to cover all roof types and shapes, and the list of required flashing locations was revised for clarity.

These are hands-on installation details, so they're worth asking about. If you're curious how drip edge and other line items show up in a quote, our line-by-line roofing estimate guide walks through them.

Tile and metal roofs

• Tile: A new section requires drip edge on tile roofs with slopes of 2:12 and greater, applied in accordance with the FRSA/TRI Florida High Wind Concrete and Clay Roof Tile Installation Manual.
• Metal panels and metal shingles: New sections require drip edge on slopes of 2:12 and greater, fastened at a maximum of 4 inches on center and installed over the underlayment.
• Metal hip and ridge covers: These must now be tested for uplift resistance under the ANSI/MCA FTS-1 standard.

You may also see headlines about tile underlayments needing product approval with tested uplift resistance. That Miami-Dade notice is about the High-Velocity Hurricane Zone provisions, which cover Miami-Dade and Broward counties. For tile underlayment in Manatee and Sarasota, our tile underlayment article covers the basics, and your roofer can tell you what the 2026 code requires for your product.

Near the water? Watch the fasteners

One of the bigger changes for the Suncoast is a new corrosion-resistance section for fasteners and metal connectors within 3,000 feet of a saltwater coastline. The roofing sections for nails, screws, and clips now point to it. It sets out stainless steel, enhanced galvanizing, and standard galvanizing options, and the level required depends on how close the building is to the shoreline and how exposed the fastener is to salt air.

Many homes on Anna Maria Island, Longboat Key, Siesta Key, and along the coast fall within that distance. Whether yours does, and which level applies, is something your building department and roofer work out for your address, so ask about it when you're comparing quotes.

Reroofing over what's already there

The rules on when a roof can be recovered instead of torn off were also updated:

• Where two roof coverings already exist, the code now allows removing just the upper layer or system, as long as what's left is adequate for the new roof. The Florida Roofing and Sheet Metal Contractors Association, which proposed the change, says it's aimed mainly at situations like reusable rigid insulation or lightweight insulating concrete, which are more common on low-slope and commercial roofs.
• Where a self-adhered membrane or vapor barrier is already adhered to the roof deck, it may stay in place and be covered with an additional layer of membrane, following the roof covering rules.
• Roof coatings now have their own section, with material standards in a new table.

For most homes with a single layer of shingles, a replacement still means tearing off to the deck. Our 25% roof rule explainer covers when a repair can become a full replacement.

Should you rush to beat December 31?

Not just because of the code. A roof permitted under either edition has to meet the code it's permitted under, and the 2026 changes are refinements, not a different kind of roof. What the deadline really affects is planning. If your roof already needs replacing, it's worth knowing which edition your job will fall under so the quote, the materials, and the permit all line up. Our Manatee and Sarasota roof permit guide explains how the permit process works step by step.

Questions to ask your roofer

1. Will my permit application be submitted before or after December 31, 2026, and which code edition will it fall under?
2. How will the hip and ridge shingles be attached, and are they labeled for the modified UL 2375 test?
3. How is the drip edge fastened, and at what spacing?
4. Is my home within 3,000 feet of a saltwater coastline, and what fasteners and clips does that call for?
5. If my roof has more than one layer, or a self-adhered membrane on the deck, what does the code allow you to leave in place?
