Commercial roofing in Waldo, FL

For new low-slope roofs under the Florida Building Code, the minimum design slope is one-fourth unit in 12, which is 2 percent, for built-up, modified bitumen, single-ply, spray foam and liquid-applied systems. A bid that leaves slope unaddressed on a flat roof deserves a direct question.

The code also requires positive drainage, meaning the roof drains within 48 hours of rain. Storm drainage is sized from rainfall data, so ask the bidder how the new system handles ponding and whether secondary overflow drains are needed where a parapet traps water.

Waldo is in Alachua County, which has no coastline and is not in the High-Velocity Hurricane Zone. That zone covers only Miami-Dade and Broward, so the HVHZ roofing rules do not apply here. Use the standard Florida Building Code and your local building office for the permit.

Before you compare prices, confirm that the bidder is a licensed roofing contractor under Florida law. A general contractor may not advertise as a roofer unless certified or registered as one. Also ask whether a Notice of Commencement will be recorded before the first inspection, because the building office may require a copy.

Compare bids on the same scope: slope, drain details, edge metal tested to the standards the code names, and whether the price covers tear-off. Ask each bidder to state their permit timeline, since a permit can lapse after 6 months without work.
