Commercial roofs ยท Tamiami

Commercial roofing in Tamiami, FL

In Tamiami, 17.9 percent of homes are in buildings with 10 or more units, according to the Census Bureau's 2024 five-year estimates. Because of this, a big portion of the jobs we take on involve roofs spanning several units. Property managers and association boards usually decide these jobs, and the county, not a city, issues the permits.

Code and permits

Which code rules apply to commercial roofs in Tamiami

Only two Florida counties fall inside the High-Velocity Hurricane Zone, and Miami-Dade is one of them. Any roof work on a commercial building here falls under the stronger HVHZ provisions, not the general statewide code. Tamiami sits inside that county boundary, so the county building office handles the permit.

HVHZ work requires an HVHZ Uniform Roofing Permit Application completed by a licensed contractor, and every permitted roofing job gets inspected. Ask the contractor for the permit number before work starts, and check the county's permit records yourself.

Drainage and systems

Low-slope drainage and membranes to ask about

Many commercial roofs in this area are low-slope. Florida requires new low-slope roofs in the HVHZ to have at least a quarter-inch of slope per foot of run, and HVHZ rules bar loose-laid ballasted systems. Ask the bidder how the design will drain within 48 hours of rain.

  • Confirm the deck slope meets the quarter-inch-per-foot minimum for new construction.
  • Ask how secondary overflow drains or scuppers are sized where parapets could trap water.
  • Ask whether the membrane standard is ASTM D4637 for EPDM, D6878 for TPO, or D4434 for PVC.
  • Ask what edge metal was tested under ANSI/SPRI ES-1 or RAS 111.

Comparing bids

How to compare bids for a Tamiami building

Compare bids on the same scope. Ask each bidder whether the price includes tear-off to the deck, which Florida rules require when the existing roof is water soaked, deteriorated, or already has two or more layers of covering.

Florida requires a roofing contractor to hold the roofing certification or registration. A general contractor who sells roofing needs that credential too. Check the state license before you sign.

Questions

Commercial roofing in Tamiami: questions

Do all commercial roofs in Tamiami need Miami-Dade approval?

Products must have a current Miami-Dade Notice of Acceptance because Tamiami is inside Miami-Dade County, which is part of the High-Velocity Hurricane Zone. Miami-Dade's Product Control Section reviews and approves roofing products, so the NOA is the approval to look for. Ask the contractor for the NOA number and its expiration date, and check it against county records before work begins.

How much of a building's roof can be repaired in a year?

Under the 25 percent rule, not more than 25 percent of the total roof area can be repaired, replaced or recovered in any 12-month period unless the entire roof system is replaced or recovered. Tamiami follows the HVHZ version of this rule, and the county building office confirms how it applies to your building.

Why does drainage matter on flat commercial roofs here?

Positive roof drainage means the roof drains within 48 hours of precipitation. Tamiami sits in a county where the 1991-2020 normal rainfall at Miami International Airport is 67.41 inches a year, so ponding is a real concern. Ask the bidder how the design handles water, and confirm with the building office.
