Commercial roofing in Palm City, FL

Only 4.2 percent of Palm City homes are in buildings with 10 or more units, so large flat-roof buildings here are the exception. Most of what you manage is likely small commercial, townhome or association work. Martin County's Building Department issues the roof permit, and the county sits outside the High-Velocity Hurricane Zone.

Permits and code

Who permits a commercial roof in Palm City

Palm City is unincorporated, so the Martin County Building Department issues your roof permit, not a city office. The special hurricane zone covers Miami-Dade and Broward only, and Martin County is outside it. The Miami-Dade Notice of Acceptance route and the HVHZ roofing permit application do not govern your job.

The statewide Florida Building Code does apply. Its Eighth Edition took effect December 31, 2023, and the Ninth Edition covers applications filed on or after December 31, 2026. Roofing products must carry statewide approval, and you can look each one up by its FL number in the Florida Building Commission search.

Flat roof basics

Low-slope systems, drainage and wind edges

Many small commercial buildings here carry low-slope roofs: built-up, modified bitumen, or single-ply such as TPO or PVC. The code sets a minimum slope of one-fourth unit in 12 for new work. Stuart averages 62.72 inches of rain a year, so drainage matters more than the membrane brand.

Florida defines positive drainage as water clearing the roof within 48 hours of rain. A parapet that can trap water calls for secondary overflow drains or scuppers. If your existing roof ponds after a storm, ask for a structural review before any recover.

Edge metal on low-slope roofs has to pass ANSI/SPRI ES-1 or RAS 111 testing. Edges are where wind starts peeling a membrane. Ask each bidder to name the edge product and its test.

Comparing bids

How a property manager should compare bids

  • Written scope: tear-off or recover, and the deck repairs included.
  • A recover is barred over a soaked roof or one with two or more existing coverings.
  • Product names with FL approval numbers you can check yourself.
  • The permit applicant named, and who records the Notice of Commencement.
  • Who handles rooftop equipment if it must be moved.

Verify the roofing contractor's state license yourself. A general contractor may not hold itself out as a roofer without roofing certification or registration, and must subcontract roofing work otherwise. Permits also expire if work does not start within 6 months.

Questions

Commercial roofing in Palm City: questions

What is the 25% roof rule in Florida for commercial buildings?

The rule limits repair, replacement or recover to 25 percent of a roof or roof section in any 12-month period. Beyond that, the entire roof or section must be redone. Roofs built or redone under the 2007 Florida Building Code or later get a narrower requirement, and a county cannot amend that carve-out. Confirm how your roof sections are counted with the Martin County Building Department.

Do I need a permit for commercial roofing in Palm City?

Yes for replacement or substantial repair. Palm City is unincorporated, so Martin County's Building Department issues the permit. After a storm the county's guide says temporary tarping needs no permit, while replacements and substantial repairs do, with fees waived and review expedited. Permits lapse if work does not start within 6 months of issue.

Does Martin County use the Miami-Dade roofing rules?

No. The High-Velocity Hurricane Zone covers only Miami-Dade and Broward counties, and Martin County is not in it. Palm City follows the statewide Florida Building Code, and roofing products still need statewide approval. A Miami-Dade Notice of Acceptance has its own expiration date and is honored outside that county only at the building official's discretion, so ask the Martin County office before relying on one.

Can my commercial roof be recovered instead of torn off?

Sometimes. The code bars a recover when the existing roof is water soaked or deteriorated, has two or more coverings, or has blisters that are not cut and secured. It also bars recover over wood shake, slate, clay or cement tile. In a county with about 62.72 inches of yearly rain, a wet roof is common, so have your contractor write down why recover is allowed before you accept it.

Is metal roofing allowed on commercial buildings in Palm City?

Yes, where it carries statewide product approval and meets the wind-load and edge-test rules in the Florida Building Code. Ask the bidder for the FL approval number and confirm it in the state search. Martin County's Building Department issues the permit, and the county is outside the High-Velocity Hurricane Zone.
