Hilton Head Island–Bluffton, SC Metropolitan Statistical Area (Lowcountry) Metal Roofing

Beaufort County and its municipalities (Town of Hilton Head Island, Town of Bluffton, City of Beaufort, Town of Port Royal) enforce the South Carolina Building Codes (IRC/IBC state-adopted editions) with coastal amendments. Design wind speeds along this stretch of coast are approximately 140-150 mph (Risk Category II, ASCE 7 map per SC code), placing Hilton Head/Bluffton in one of the higher wind-design zones in SC, though not an official "High-Velocity Hurricane Zone" (HVHZ applies only in South FL). Hilton Head Island and Bluffton both administer FEMA-mapped flood zones (VE coastal high-hazard velocity zones along oceanfront/marshfront, AE elsewhere) requiring elevated construction, breakaway walls, and freeboard above base flood elevation in flood-prone parcels. Hilton Head Island has a Land Management Ordinance (LMO) with strict tree-preservation, dark-sky/lighting, and architectural review requirements administered by the Town's Community Development Dept and by private plantation Architectural Review Boards (ARBs/POAs) — metal roof color, finish, and profile approvals are frequently required by both the Town and the gated community's ARB before permitting. Bluffton likewise requires Design Review Board (DRB) approval in Old Town Bluffton's historic district and in planned communities like Palmetto Bluff and Sun City. Coastal Construction Control zones and DHEC-OCRM (SC Dept of Environmental Services, Ocean & Coastal Resource Management) setback jurisdiction apply near the beach/critical line. No Wildland-Urban Interface (WUI) code overlay in this metro (unlike western states) — primary local perils driving metal-roof specification are wind uplift resistance, corrosion resistance, and impact/missile-borne debris requirements in windborne debris regions near the coast.
