Commercial roofing in Indiantown, FL

Roof permits in Indiantown run through the Village of Indiantown building office. Only Miami-Dade and Broward counties fall within the High-Velocity Hurricane Zone, so Martin County lies outside it. That means the stricter HVHZ roofing permit and inspection steps do not apply here, though the wider Florida Building Code still does.

Partial projects are where the 25 percent rule comes into play. Current code caps repairs, replacements and recovering at 25 percent of a roof in any 12-month window, except when the whole roof covering gets replaced. A roof built or repaired under the 2007 code or later only needs the repaired section brought up to current code.

Ask each bidder for the membrane type and the exact ASTM standard it meets. Single-ply TPO sheet, for example, should match ASTM D6878, and PVC sheet should match ASTM D4434. Compare the written slope and drainage plan too, since minimum design slope for new low-slope roofs is one-fourth unit in 12 for many systems.

• Specify the membrane material and the ASTM standard it satisfies.
• Drainage plan, including secondary overflow drains where parapets trap water
• Whether the bid includes replacing wood sheathing found during tear-off
• Who pulls the permit and records the Notice of Commencement

Stuart's 62.72-inch normal annual rainfall, with 92 days of measurable rain, is a useful baseline for drainage design in this part of the county. Ask bidders how they will keep water moving off the roof within 48 hours of rain.
