Roofing in Broward County HVHZ requires Miami-Dade NOA products, enhanced deck attachment, secondary water barrier, and hurricane strap tie-downs. 25 percent roof replacement triggers full code compliance.
Roofing in the Broward County High-Velocity Hurricane Zone (HVHZ) must meet the Florida Building Code HVHZ provisions in Chapter 15. All roof covering products including shingles, tiles, metal panels, and low-slope membranes must carry a current Miami-Dade Notice of Acceptance (NOA) or Florida Product Approval. Nailing patterns are prescriptive with typically six nails per shingle or greater, enhanced edge metal, and ring-shank nails for deck attachment. A secondary water barrier or self-adhered underlayment over the entire deck is required in reroof projects. When more than 25 percent of a roof section is replaced within 12 months, the entire roof system must be brought up to current code, including truss-to-wall hurricane connector straps under the 25 percent rule and the FBC Existing Building roof-deck attachment provisions. Wind uplift ratings must match the design wind speed, which ranges 170-180 mph ultimate in Broward. Roof inspections include in-progress deck nailing, dry-in, and final coverage inspections.
