Local know-how

What Miami is building, by the permit count

The Census counted 442,241 people in Miami in 2020; the 2020-2024 American Community Survey estimate is 459,745. Most of what gets permitted now goes up in larger buildings, and 19.2% of the city's existing homes were built in 2010 or later.

Countywide, single-family permits rose from 2,133 in 2020 to 2,666 in 2025. Miami's 152 are a small slice of that total, while its multifamily count leads the county. Each of those buildings needs a roof designed, permitted and inspected under the HVHZ sections of the code.

Code

Which edition a new Miami roof is permitted under

The 2023 Florida Building Code, 8th edition, has applied since December 31, 2023. Miami-Dade's building department has given notice that the 9th edition takes effect December 31, 2026, and that every permit application and plan submitted on or after that date must comply. A project's filing date, not its groundbreaking, sets the edition.

Inspections follow the code's order: framing, then sheathing (often with the dry-in), then the roofing inspection covering dry-in, insulation, coverings and flashing, then the final (FBC-B 110.3). In the HVHZ, each roofing stage is inspected before it is covered, and the permit application carries the product approval or NOA number for every component.

Roofing on a new building is a trade of its own. Under Fla. Stat. 489.113(3), a general, building or residential contractor must subcontract roofing unless it holds a roofing certificate or registration, with one exception for shingles on its own new building.

Questions

New construction roofing in Miami: questions

Does Florida's builder warranty law cover a new Miami roof?

It covers code defects for one year. Since July 1, 2025, Fla. Stat. 553.837 has required a builder to warrant a newly built home against defects in equipment, material or workmanship that cause a material violation of the Florida Building Code, for one year from title transfer or first occupancy, whichever comes first. The law leaves out ordinary wear, settling, damage the owner caused and acts of God, natural disasters included. Miami permitted 152 new single-family homes in 2025, each one covered from its closing.

What inspections does a new roof in Miami go through?

Several, each before the work is hidden. FBC-B 110.3 lists framing, sheathing and dry-in, then a roofing inspection of dry-in, insulation, coverings and flashing, then the final. In the HVHZ, FBC-B 1512.4 adds stage inspections for each system: for membranes, during application before the attachment is concealed; for tile set in adhesive or mortar, a field uplift test before the final. Inspections inside the city go through the City of Miami Building Department.

What slope does a new low-slope roof in Miami need?

At least 1/4 inch per foot. In the High-Velocity Hurricane Zone, FBC-B 1515.2.2.1 sets a minimum deck slope of 1/4:12 for new construction, and the zone's Table 1515.2 adds minimums by system, including 2:12 for architectural metal panels and 4:12 for mechanically fastened tile. Loose-laid ballasted systems are not allowed at all. With 6,863 units in larger buildings permitted in Miami in 2025, these minimums shape much of the city's new work.
