Commercial roofing in Fish Hawk, FL

Fish Hawk is unincorporated, so Hillsborough County building office issues roof permits. Ask any contractor for the permit number before work begins. A permit for a new roof on a low-slope system must follow the 2023 Florida Building Code, which took effect December 31, 2023, and the 2026 edition applies to applications filed on or after December 31, 2026.

Under the 25 percent rule, you may repair or replace no more than 25 percent of a roof's area within any 12-month period, unless you replace the entire roof covering in one project. By our arithmetic, a 40,000-square-foot roof could have up to 10,000 square feet of partial work in a year before a full replacement is required. Confirm the rule and the permit scope with the building office.

• Ask for the slope of the new roof. New low-slope roofs need at least 2 percent slope under the code.
• Ask how the bid handles drainage, since a roof must drain within 48 hours of rain.
• Ask for the material standard, such as ASTM D4637 for EPDM or ASTM D6878 for TPO.
• Ask who will pull the permit and whether the Notice of Commencement is recorded.

Fish Hawk got heavy rain from Hurricane Hermine in 2016 and freshwater flooding from storms in the region, so ponding water and blocked drains matter here. Ask how the bid addresses secondary overflow drains where the roof edge can trap water.
