Commercial roofing in Cheval, FL

Cheval is unincorporated, so roof permits go through Hillsborough County's building office, not a city office. Check the county's permit records before work starts. Florida's current building code is the 2023 Eighth Edition, which took effect December 31, 2023, and the Ninth Edition applies to permit applications submitted on or after December 31, 2026.

Low-slope roofs have a minimum design slope of one-fourth unit in 12, which is 2 percent. Built-up, modified bitumen, single-ply, spray foam and liquid-applied systems all carry that baseline. Under the 25 percent rule, no more than 25 percent of a roof area can be repaired or replaced in any 12-month period without bringing the entire roof system up to code, unless the existing roof was built to the 2007 code or later.

Ask each bidder for the roofing system type, the membrane material and the ASTM standard it meets. Single-ply TPO should cite ASTM D6878, and EPDM should cite D4637. Ask whether the bidder will address ponding water and drainage, since the code requires positive drainage within 48 hours of precipitation and secondary overflow drains where a parapet can trap water.

Florida law requires a general contractor to subcontract roofing work unless that contractor holds a roofing certification or registration, and a contractor who advertises as a roofing contractor must hold that credential. Confirm the bidder's status with the state before you sign. Ask who will pull the permit and who records the Notice of Commencement, because the code warns owners that skipping it can mean paying twice.
