Why South Miami's building stock changes commercial roofing
Commercial roofing here is often a roof on a condominium, apartment or association building. About 40 percent of Miami-Dade units sit in buildings of 10 or more units, and South Miami is close to that share. Those roofs are large, and a single leak can reach many units.
The city's housing is also older than the county as a whole. South Miami's median year built is 1969, while Miami-Dade's is 1980. Many commercial roofs in the city are likely past their first system, so a reroof decision often comes up sooner than an owner expects.
Permits and code
Permits and the High-Velocity Hurricane Zone in South Miami
Miami-Dade is one of two counties in the High-Velocity Hurricane Zone, so roofing work here follows the strongest hurricane provisions in the state. Any product you install should carry a Miami-Dade Notice of Acceptance. Keep the NOA on site, since the Building Official may request it at any point during the inspection.
Roof permits in South Miami are handled by the City of South Miami Building Division. For HVHZ work, the permit application must be completed and signed by a licensed contractor, and all roofing work is inspected. Confirm the current submittal list with the Building Division before you schedule work.
Bid comparison
Flat-roof options, water runoff, and how to weigh competing quotes
Most flat commercial roofs need a minimum slope of one-fourth unit in 12 for built-up, modified bitumen and single-ply systems. In the HVHZ, new construction must meet the same one-fourth minimum, and no loose-laid ballasted system is allowed. Ask each bidder how the roof will drain within 48 hours of rain.
- Confirm each product carries a current Miami-Dade NOA.
- Ask who pulls the HVHZ permit and who calls for inspections.
- Ask how the bid handles ponding water and overflow drains.
- Confirm the roofing contractor holds the required state roofing certification.

In Miami-Dade and South Miami, if more than 25 percent of the roof area is worked on, the entire roof covering must be replaced or recovered.
