Metal Roofing in Union
Union is a hub of the Spartanburg area of South Carolina, located in Union County (population ~7,900 (2020 city); county seat). County seat of Union County, the metro's smaller/secondary county; substantial National Register historic housing stock from 1850-1940 alongside former textile-mill villages (Buffalo, Monarch Mill).

Recommended Metal Roof Types
Standing seam steel (concealed-fastener, Galvalume or steel substrate with PVDF/Kynar coating)
Highest wind-uplift performance for hurricane-prone coastal counties (Charleston, Horry, Beaufort, Georgetown); code-favored for high Vult zones; best watertightness for wind-driven rain.
Standing seam aluminum
Preferred within a few miles of the ocean/marsh for superior corrosion resistance versus steel in chronic salt-air exposure (Lowcountry/Grand Strand barrier islands).
Stone-coated steel shake/shingle panels
Popular retrofit choice in historic districts and traditional neighborhoods (Charleston, Columbia, Greenville) wanting shingle or shake aesthetics with metal's wind/hail/fire performance.
Exposed-fastener corrugated/R-panel steel
Lower-cost option common on rural Piedmont/Upstate homes, outbuildings, and budget-conscious re-roofs; less ideal directly on the coast due to fastener corrosion risk.
Weather Perils in Union
- Severe thunderstorms with large hail (spring/summer)
- Occasional tornadoes (Piedmont tornado corridor)
- High winds and heavy rain from decaying tropical systems moving inland (e.g., Hurricane Helene remnants, Sept. 2024, caused significant Upstate SC wind and tree-fall damage)
- Winter ice storms and occasional snow/freeze-thaw cycles that stress roofing fasteners and flashing
- Elevated fall wildfire/brush-fire risk in foothill terrain near the Blue Ridge escarpment (Landrum, Campobello, Chesnee)
- UV and humidity-driven wear typical of the humid subtropical Piedmont climate
Typical Installed Cost
Approximate installed cost ranges commonly cited for residential metal roofing (materials + labor, national ranges applicable to SC, with coastal SC often at the higher end due to corrosion-resistant coatings and hurricane-rated installation detailing): exposed-fastener corrugated/screw-down steel panels roughly $6-$10/sq ft; standing seam steel (concealed fastener) roughly $9-$16/sq ft; standing seam aluminum roughly $10-$18/sq ft (coastal-recommended); stone-coated steel roughly $9-$14/sq ft; copper and zinc premium standing seam roughly $18-$30+/sq ft.
