Commercial roofing in Fort Lauderdale, FL

In Fort Lauderdale, 43.6 percent of housing units are in buildings with 10 or more units, more than the 34 percent in detached houses. That puts boards and building managers behind a large share of the city's roof decisions, and every low-slope roof they own is permitted under the High-Velocity Hurricane Zone sections of the Florida code.

Local know-how

Drainage and ponding on Fort Lauderdale flat roofs

Rain intensity is the starting point. The plumbing code sizes storm drainage on the 100-year hourly rainfall rate, and NOAA's Atlas 14 puts that rate at 5.49 inches an hour at Fort Lauderdale's Census point. The building code defines positive drainage as enough slope to clear the roof within 48 hours of rain, and it calls for secondary overflow drains or scuppers wherever a raised perimeter would trap water if the main drains back up.

The HVHZ chapters add rules aimed at owners. A re-roof or repair may not create additional ponding (1521.3), and before work starts the contractor has to tell the owner about any chance of ponding and recommend a structural review if it is possible (1521.13). Inspections follow the membrane, not just the finished roof: a continuous system is inspected during application, before its attachment to the deck is covered, and again at final (1512.4).

Questions

Commercial roofing in Fort Lauderdale: questions

Are ballasted flat roofs allowed in Fort Lauderdale?

No. Section 1515.1.5 of the Florida Building Code says no loose-laid ballasted or non-ballasted system is permitted in the High-Velocity Hurricane Zone, which takes in all of Fort Lauderdale. Low-slope systems here are attached to the deck, and that attachment is inspected during application, before it is covered (1512.4). With 43.6 percent of the city's housing units in buildings of 10 or more units, the rule shapes association roofs as much as shops and offices.

Does a Fort Lauderdale condo tower need a roof reserve study?

A tower qualifies as soon as it has three habitable stories, so every condo high-rise in the city is covered. Under Fla. Stat. 718.112(2)(g), a residential condominium association must complete a structural integrity reserve study at least every 10 years for each such building, and the roof is the first item the study has to cover. The study rests on a visual inspection and estimates each item's remaining useful life, which gives a board a dated number to plan the next roof around. Fort Lauderdale permitted another 1,052 units in buildings of five or more units in 2025, and any of those buildings that reach three habitable stories will join that schedule.

What happens to rooftop A/C units during a Fort Lauderdale re-roof?

Existing units usually stay as they are. Under FBC-B 102.8, a local government may not require existing mechanical equipment on a roof to be brought up to the Florida Building Code, except during reroofing when the equipment is being replaced or moved and does not comply. Florida law also treats equipment fastened to code on rated stands or curbs as meeting the 2007 code's wind requirements (Fla. Stat. 553.844(4)). On Fort Lauderdale's condo and office roofs, where 43.6 percent of homes sit in 10-plus-unit buildings, ask early whether any unit will be moved or swapped during the job.
