Commercial roofs ยท Biscayne Gardens
Commercial roofing in Biscayne Gardens, FL
In Biscayne Gardens, 27.1 percent of homes are in buildings with 10 or more units, a larger share than many Florida towns of similar size. That makes multi-unit roofs, association buildings and low-slope systems the core of commercial roofing work here. Miami-Dade is also in the High-Velocity Hurricane Zone, so the code and permit path differ from most of Florida.

Local building stock
Why multi-unit and association roofs dominate Biscayne Gardens
The Census estimates that 40.2 percent of units here sit in buildings of 10 or more units, and only 38.8 percent are single-family detached homes. That suggests a large share of commercial-style roof decisions will fall to property managers and associations rather than individual owners.
The median home here was built in 1965, and 77.8 percent of units predate 1980. Many of these flat or low-slope roofs are likely decades past their original install, so a manager should expect condition surveys before any bid.
HVHZ and permits
Which code and permit rules apply to a commercial re-roof
Because Miami-Dade is in the High-Velocity Hurricane Zone, a roofing permit needs an HVHZ Uniform Roofing Permit Application completed by a licensed contractor, with product approval and detail drawings attached. Each new, recovered or repaired roof is inspected before the full concealment of the adhesion or attachment process.
Permits for Biscayne Gardens are issued by the county building office, Miami-Dade Regulatory and Economic Resources. Confirm the current permit status there before work starts, since a permit becomes invalid if work does not begin within 6 months of issuance.
Comparing bids
What to look at when you set commercial roofing bids side by side
- Confirm the roof slope meets the minimum of one-fourth unit in 12 for new low-slope work.
- Ask how the bid handles ponding water and whether a structural review is recommended.
- Check that single-ply materials are listed by ASTM standard, such as D6878 for TPO or D4637 for EPDM.
- Confirm the product carries a current Miami-Dade Notice of Acceptance and that the contractor can show it on site.
- Ask who will file the Notice of Commencement before the first inspection.
Ask each bidder to state drainage design. Positive drainage means the roof drains within 48 hours of rain, and HVHZ rules bar any work that creates additional ponding water.
Questions
Commercial roofing in Biscayne Gardens: questions
Do commercial roofs in Biscayne Gardens need a permit?
Yes. Biscayne Gardens sits in Miami-Dade County, which is in the High-Velocity Hurricane Zone, so all new, recovered, repaired or maintained roofing needs a permit. The application must be completed by a licensed contractor and filed with Miami-Dade Regulatory and Economic Resources, the county office that issues permits here. Confirm current requirements there before starting work.

What slope does a low-slope roof need here?
For new low-slope roofs, the minimum design slope is one-fourth unit in 12, which is 2 percent. In the HVHZ, the minimum for new deck slope is also 1/4:12. Ask your contractor to show the slope on the plans before you approve a bid.

Can a building in Biscayne Gardens get a roof recover instead of a tear-off?
Not always. In Biscayne Gardens, 77.8 percent of units predate 1980, so many existing roofs here may be deteriorated. Recovering is barred and a full tear-off to the deck is required if the existing roof is water soaked or deteriorated, if it already has two or more layers of covering, or if blisters exist unless they are cut and secured. Have a condition survey done first.

How do I check that a roofing product is approved in Miami-Dade?
Ask for the Miami-Dade Notice of Acceptance number and check it against the county's product approval records. In Miami-Dade, the Product Control Section reviews and approves building-envelope products, including roofing, so the NOA is issued there. The NOA shows an expiration date, and it must be available at the job site when the building official asks. Misuse of an NOA as an endorsement can terminate it. Local context matters here: the county's housing stock is large and varied, and a 2020 count of 27.1 percent of homes in buildings with 10 or more units shows how many multi-unit properties rely on approved envelope products.
