Commercial roofing in South Palm Beach, FL
In South Palm Beach, 89.7 percent of homes are in buildings with 10 or more units, so most roofs you will manage here are large, flat, shared roofs. The town is a barrier island, and most of its growth came through condominiums built in the early 1970s. A property manager here is usually comparing bids for a low-slope system on an older multi-unit building, not a single family house.

What older multi-unit roofs in South Palm Beach need
About 75.9 percent of the town's housing units were built before 1980, against 33.5 percent across Palm Beach County. The median build year is 1975. That suggests many shared roofs here are past their first full cycle, and a manager should expect tear-off to the deck to come up more often than a recover.
Under Florida's 25 percent rule, if you repair or replace more than a quarter of an existing roof within any 12-month span, the entire roof system must meet current code. A roof built to the 2007 Florida Building Code or later can often be partly repaired without that trigger, so ask for the original permit record before you choose a scope.
- Confirm the permit history with the Town of South Palm Beach Building Department before bidding.
- Ask each bidder whether the existing deck is sound enough to take a new covering, since a soaked or deteriorated base cannot take a recover.
- Check whether rooftop equipment is being moved, because replacement of equipment during reroofing can bring it up to code.
Low-slope systems
Drainage, edges and the code that applies here
Only Broward and Miami-Dade counties fall inside the High-Velocity Hurricane Zone, so Palm Beach County lies beyond its boundaries. That means the HVHZ roofing chapter does not govern a South Palm Beach job. The general code still sets a minimum design slope of one-fourth unit in 12 for built-up, modified bitumen, single-ply and liquid-applied roofs, so ask bidders to show that slope on the drawings.
A roof with positive drainage sheds standing water within two days of a storm. Engineers size storm drains using the hourly rainfall rate expected once every 100 years. At West Palm Beach International Airport the normal annual rainfall is 61.75 inches, with 86.1 days a year at 0.10 inches or more. Ask each bidder how the design handles ponding, and whether secondary overflow drains or scuppers are required where a parapet can trap water.
Metal edge systems on low-slope roofs must be designed for the wind loads in Chapter 16 and tested to ANSI/SPRI ES-1. Ask bidders to name the edge test method on their submittal, not only the membrane.
Permits and bids
Who permits commercial roofing in South Palm Beach
The Town of South Palm Beach Building Department is where roof permits for South Palm Beach get issued. Confirm the current permit process directly with that office before scheduling work, because the town's page is the authority on local submittal steps.
Florida requires a roofing contractor to hold the right certification or registration for roofing work. A general contractor must subcontract roofing unless it holds that roofing registration, so confirm each bidder's status with the state before you sign. Florida's Notice of Commencement must be recorded and posted before the first inspection on a large job.
Questions
Commercial roofing in South Palm Beach: questions
Does the High-Velocity Hurricane Zone apply to a commercial roof in South Palm Beach?
Palm Beach County is not part of the High-Velocity Hurricane Zone, which applies only to Broward and Miami-Dade counties. A South Palm Beach job falls under the general Florida Building Code roofing chapters. Ask bidders to state which code sections they are designing to, and confirm the answer with the Town of South Palm Beach Building Department before you sign.

How much of a condo building's roof can be repaired without replacing the whole system?
Florida's 25 percent rule allows no more than 25 percent of the roof area to be repaired, replaced or recovered in any 12-month period without bringing the entire roof up to current code. Because 75.9 percent of South Palm Beach's homes were built before 1980, many shared roofs here may be older. Check the original permit record first, since a roof built to the 2007 code or later may be treated differently.

What slope should a flat commercial roof here have?
The code sets a minimum design slope of one-fourth unit in 12, which is 2 percent, for most low-slope systems. When your roof has positive drainage, water is gone from its surface within 48 hours after rain stops. At West Palm Beach International Airport the normal annual rainfall is 61.75 inches. Ask each bidder to show slope and overflow drains on the drawings before comparing prices.

What should a property manager check when comparing commercial roofing bids?
Compare the drainage design, the edge system and the permit scope, not just the membrane. Ask for the edge test method under ANSI/SPRI ES-1, and confirm the roofing subcontractor's status with the state. With 89.7 percent of South Palm Beach homes in buildings of 10 or more units, a shared roof usually affects many owners, so get every bid on the same scope.
