Roof replacement in Marion County, FL

Marion County's median home was built in 1993, and 62.5% of its homes went up before 2000, a decade or more ahead of the 2007 Florida Building Code, which took effect on March 1, 2009. On those houses, a roof replacement in Marion County reaches past the shingles: the old deck nailing and the water barrier get brought up to today's code.

Replacing a roof in Marion County: the short version

Pull the permit from the office that covers your address: Marion County Building Safety for unincorporated areas, or the building office in Ocala, Belleview or Dunnellon. Reroofs skip plan review, then pass a sheathing inspection and a roofing inspection. Older decks often need extra ring-shank nails, every tear-off gets a secondary water barrier, and a roof not built to the 2007 code or later can only be patched 25% a year.

What a 1990s deck needs at tear-off

The residential code treats a re-roof on an existing house as the moment to fix the deck. When the covering comes off a plywood, OSB or plank deck, the attachment has to meet R908.7.1 and a secondary water barrier has to go down under R908.7.2.

The nailing table is specific. Decks held by staples or 6d nails, at any spacing, get supplemental ring-shank nails no more than 6 inches apart. Decks with 8d nails already at 6 inches or closer need nothing more, and wider 8d spacing gets filled in to 6 inches.

With half of Marion's houses dating from 1993 or earlier and only 13.5% from 2010 on, expect the inspector to look hard at the deck. The water barrier can be a fully adhered membrane, taped deck seams under underlayment, or two layers of felt-type underlayment fastened on a tight schedule (R905.1.1.1).

Permits

Permit, plan review and two inspections

A re-roof needs a building permit, but reroofs are on the code's list of work that skips plan review (FBC-B 107). Unincorporated communities such as Silver Springs Shores and Marion Oaks point to Marion County Building Safety, while Ocala, Belleview and Dunnellon keep their own building offices. In McIntosh, get the town's written authorization before the county application.

Two inspections follow. The sheathing inspection checks roof sheathing and its fasteners, either at dry-in or as a separate visit. The roofing inspection covers dry-in, insulation, the roof covering and flashing at a minimum (FBC-B 110.3).

Keep the job moving once the permit issues. It becomes invalid if work does not start within 6 months, and a passed inspection within 180 days keeps the work counted as active (FBC-B 105.4.1).

Repair or replace

Storm damage and the 25% line

Florida's code caps patching at 25% of a roof or roof section in any 12-month period. Go past that, and the whole roof or section has to be redone to current code (R908.1.1).

One exception splits Marion's housing stock. If the existing roof was built, repaired or replaced to the 2007 Florida Building Code or later, only the part being fixed must meet today's code, even past 25% (Fla. Stat. 553.844(5)). A roof put on before the 2007 edition took effect in 2009 does not get that break.

After a storm like Milton, which brought the county a federal declaration in 2024, a pre-2009 roof with more than a quarter of a section torn up crosses that line. The rule says nothing about who pays; that is a question for your insurer or agent.

Timing

Which code edition your permit lands in

The 8th edition of the Florida Building Code has applied since December 31, 2023. The 9th edition takes effect December 31, 2026, and permit applications submitted on or after that date must follow it. If you are filing close to that date, ask your building office which edition will govern the job.

Questions

Roof replacement in Marion County: questions

Do I need a permit to replace my roof in Marion County?

Yes. The Florida Building Code requires a permit to alter or repair a building, and a re-roof is no exception, though it is spared plan review. In unincorporated Marion, including Liberty Triangle and On Top of the World, our research points to Marion County Building Safety as the issuing office. Inside Ocala, Belleview or Dunnellon, the city issues it. Reddick had no office we could find, so ask the town before you schedule anything.

Milton tore up part of my roof. Do I need a whole new roof?

It depends on how much was damaged and when the roof went on. If more than 25% of the roof or a roof section needs work within 12 months, the code calls for the whole roof or section to be redone, unless the existing roof was built to the 2007 Florida Building Code or later. Milton left 9.68 inches of rain south of Ocala, and water under torn shingles can widen the damaged area. What your policy pays is a question for your insurer or agent, not the code.

Related: FAQ

My Marion County house was built after 2010. Do the deck nailing rules still apply?

They apply to every re-roof where the covering comes off a wood deck, but a newer deck may already pass. If the sheathing is held by 8d nails at 6 inches or closer, the table asks for nothing more; staples or 6d nails get extra ring-shank nails. About 13.5% of Marion's homes were built in 2010 or later, and a roof built to the 2007 code or newer also qualifies for the exception to the 25% repair limit.

Related: Roof replacement

Can new shingles go over my old ones in Marion County?

Not if the roof already has two layers, is water-soaked or worn past being a base, or is tile, slate or wood shake: in those cases Florida's residential code requires a full tear-off (R908.3). Beyond that, the 8th edition's re-cover sections read “Reserved,” so whether a layover is accepted is up to the building office. Ask Marion County Building Safety, or your city office in Ocala, Belleview or Dunnellon, before you plan one.
