What commercial roofs in The Hammocks look like

The Hammocks is a planned community with a mix of housing. About 50.7 percent of homes are single-family detached, and 22.1 percent sit in buildings with 10 or more units. That means many associations and managers here are responsible for flat or low-slope roofs on multi-unit buildings, not only pitched shingle roofs.

Miami-Dade sits inside the High-Velocity Hurricane Zone, the only zone that also covers Broward County. That zone carries the strongest hurricane provisions in the Florida Building Code, adopted after Hurricane Andrew. A commercial roof bid for a Hammocks building has to meet those provisions, not only the general state code.

  • Minimum design slope for new low-slope roofs is one-fourth unit in 12, about 2 percent.
  • Single-ply membranes such as TPO, EPDM and PVC must meet listed ASTM standards.
  • Ballasted loose-laid roofs are not permitted in the HVHZ.

Permits and bids

Who permits commercial roofing here and how to compare bids

The Hammocks is an unincorporated census-designated place, so the Miami-Dade County Regulatory and Economic Resources office issues roofing permits. HVHZ work needs an HVHZ Uniform Roofing Permit Application completed by a licensed contractor, and the inspections cover each stage of the work.

When you compare bids, ask each contractor for the product approval number and the Notice of Acceptance for every roofing product in the proposal. Confirm the approval on the Florida Building Commission product search before you sign. Miami-Dade's Product Control Section approves roofing systems, so a bid that names a product without an approval number needs a follow-up question.

Questions

Commercial roofing in The Hammocks: questions

Do roofing contractors in Miami-Dade need a state roofing certification?

In Miami-Dade County, where 22.1 percent of Hammocks homes are in buildings with 10 or more units, the HVHZ permit application must be completed by a licensed contractor, so ask any bidder to show that status before you accept a proposal.

Who issues commercial roofing permits in The Hammocks?

The Hammocks is unincorporated, so the Miami-Dade County Regulatory and Economic Resources office issues the permit, not a city. Check the county Building and Permits page before you schedule work. Confirm the current permit requirements with the county building office, since that page was checked on a single date.

What should I check on a low-slope roof bid?

Check the membrane type, the ASTM standard it meets, the drainage plan, and the edge system. In The Hammocks, where 22.1 percent of homes sit in buildings with 10 or more units, large low-slope roofs are common, so ask for drainage details. Under the HVHZ rules, the contractor must notify the owner if ponding water is possible and recommend a structural review.

How long does a roof permit stay valid in Miami-Dade?

A Miami-Dade roof permit becomes invalid if work does not start within 6 months of issuance, or if work stops for 6 months. In The Hammocks, where 22.1 percent of homes are in buildings with 10 or more units, multi-stage projects often run long, so track the 180-day inspection window closely. Work counts as active only when it passes an inspection within that window.
