Commercial roofing in Orlando, FL
Just 31.6% of Orlando's housing units are detached single-family homes, against 54.1% across Orange County, so most of the city's housing sits in attached or multi-unit buildings. Commercial roofing in Orlando, FL covers those apartment and condominium roofs along with the city's business buildings, and Florida's code treats them differently from a house.

Local know-how
Orlando's shared roofs and who answers for them
Orlando has 148,754 housing units, and fewer than a third are detached houses. Only 39.5% of occupied homes are owner-occupied, so many roof decisions here belong to associations and landlords. For condominium buildings three habitable stories or higher, Florida law requires a structural integrity reserve study at least every 10 years, and the roof is the first item it covers (718.112(2)(g)). Its findings come from a visual inspection, item by item, with a remaining-life estimate for each one, the roof included.
Inside city limits, commercial roof permits come from City of Orlando Permits & Inspections, and older commercial buildings in the city's six preservation overlay districts also face the Certificate of Appropriateness review. Orange County sits outside the High-Velocity Hurricane Zone, which the code limits to Broward and Miami-Dade, so Orlando roof decks and coverings are designed for wind under the standard Chapter 15 and 16 rules rather than the HVHZ sections.
Florida code
Low-slope rules that apply to Orlando buildings
Most low-slope systems, from built-up and modified bitumen to single-ply and spray foam, need a design slope of at least one-quarter inch per foot. The code defines positive drainage as a roof that drains within 48 hours of rain, and where parapets could trap water behind blocked drains, secondary overflow drains or scuppers are required. Roof drainage is sized on the 100-year hourly rainfall rate, which NOAA Atlas 14 puts at 3.92 inches an hour inside Orlando's city limits.
Edges and coatings get their own rules. Metal edge systems on low-slope built-up, modified bitumen and single-ply roofs must be wind-designed and tested to ANSI/SPRI ES-1 or RAS 111. A coating sold to stop leaks or extend a roof's life counts as roofing work under Florida's contractor law. For scale, Hurricane Irma's peak gust reached 69 knots at Orlando International in 2017.
Questions
Commercial roofing in Orlando: questions
Does my Orlando condo association need a roof study?
Yes, when the association's building is a residential condominium with three or more habitable stories. Fla. Stat. 718.112(2)(g) requires a structural integrity reserve study at least every 10 years, and the roof is the first item it covers. The study is based on a visual inspection and gives each item's remaining useful life. Many Orlando homes sit in shared buildings, since only 31.6% of the city's housing units are detached houses, so ask your association's manager when the last study was done and what it said about the roof.
How long can water stand on a flat roof in Orlando?
Not long. Florida's building code defines positive roof drainage as a roof that drains within 48 hours of precipitation, and NRCA uses the same 48-hour line for ponding when conditions allow drying. Orlando International averages 51.45 inches of rain a year, with 23.20 inches falling from June through August alone, so a roof that holds water after one storm will often be holding more after the next. Standing water past 48 hours is a drainage problem to correct, not a feature of flat roofs.
Can a commercial roof in Orlando be recovered instead of torn off?
Sometimes. Florida's code bars a recover when the existing roof is water-soaked or too deteriorated to be a base, when it already has two or more layers, when blisters have not been cut and secured, or when the old covering would serve as attachment and wind securement cannot be met. A moisture survey verified by core samples tells you which case you are in. A separate standing-seam metal system that carries its own loads may go over an existing roof. Permits for buildings in the city go through City of Orlando Permits & Inspections.
