Commercial roofing in High Springs, FL

High Springs is inside Alachua County, which has no coastline. The county is not in the High-Velocity Hurricane Zone, so the HVHZ permit and product rules that apply in Miami-Dade and Broward do not govern a commercial roof here. The state product approval search still matters for any wind-rated component, and the 2023 Florida Building Code, Eighth Edition, is the code in force for permits now.

The 25 percent rule applies to your building. Repairs or replacements covering more than 25 percent of your roof area within a 12-month window trigger a requirement to replace the full roof covering. If your existing roof was built, repaired or replaced to the 2007 code or later, only the repaired part must meet current code. Ask the City of High Springs Building Department which edition your roof was permitted under.

Ask every bidder for the same details: the membrane type, its ASTM standard, the slope it will leave the deck at, and how the edges are secured. Low-slope roofs in Florida need a minimum design slope of one-fourth unit in 12 for most systems, so a bid that does not address slope or ponding is incomplete.

Ask how the bidder will handle drainage. Florida sizes storm drains from the 100-year hourly rainfall rate, and an overflow drain or scupper is needed where a parapet would trap water. A roof that ponds water for longer than 48 hours after rain is not positive drainage under the code definition.
