Commercial roofing in Melbourne, FL
Melbourne's 41,217 housing units hold a larger share of shared roofs than the county as a whole: detached houses are only 57.2% of the stock here, against 65.9% across Brevard. Commercial roofing in Melbourne, FL covers those apartment and condominium roofs and the business buildings beside them, under Chapter 15 of the Florida Building Code.

Drainage
Low-slope drainage for Melbourne's summer storms
Melbourne International records 20.27 inches of rain from June through August. On a low-slope roof, the code's test is positive drainage: the roof should shed water within 48 hours of a rain. Where a parapet or raised edge would trap water if the main drains back up, overflow drains or scuppers are required.
Drain sizing in the plumbing code runs on the 100-year hourly rainfall rate; NOAA Atlas 14 puts it at 4.32 inches an hour at Melbourne's own data point. New built-up, modified bitumen, single-ply and liquid-applied roofs also need at least a quarter inch of slope per foot.
Before a recover, find the wet areas. Infrared surveys work because wet sections hold heat longer at night, but the readings are relative; core cuts confirm them, and a water-soaked roof is not a base for a new one.
Questions
Commercial roofing in Melbourne: questions
Which single-ply membranes does the Florida code list for Melbourne roofs?
The 2023 Florida Building Code's single-ply table lists EPDM (ASTM D4637), TPO (ASTM D6878), CSPE and PIB (ASTM D5019), KEE (ASTM D6754) and PVC sheet under ASTM D4434; in Florida, TPO and PVC sit inside section 1507.12. Every low-slope covering must also hold up through 2,000 hours of accelerated weathering tests. Any of them on a Melbourne building goes through the City of Melbourne Building Section for its permit.

Can a coating fix a leaking flat roof in Melbourne?
Sometimes, but check three things first. The roof must drain, because the code expects water gone within 48 hours, and a coating has to be rated for any ponding that remains. The roof under it cannot be water-soaked. And a coating sold to stop leaks or extend roof life counts as roofing work under Florida law. With 50.79 inches of rain a year at Melbourne International, a coated roof that ponds will be tested often.

Does the A/C on a Melbourne commercial roof have to meet current code during a re-roof?
Only in one case. A local government may not require existing rooftop mechanical equipment to meet the current Florida Building Code except during reroofing, when the unit is being replaced or moved and is not in compliance. Equipment fastened to code on rated stands or curbs is deemed to meet the 2007 code's wind rules. Detached houses are 57.2% of Melbourne's housing, so apartment and condominium roofs with units on top are common here; plan the re-roof and any unit swap together.
