Standing-Seam Metal Roofing & Sheet Metal in Greenville, SC
Long-life metal roofs for commercial and industrial buildings, plus the custom sheet metal that finishes every roof OTC installs. The name says it: OTC Roofing & Sheet Metal Co.
Metal that outlasts the mortgage
Standing-seam roofs hide their fasteners under raised seams that run from eave to ridge, so there are no exposed screws to back out and leak. Panels expand and contract on clips, which matters through hot summers and cold snaps. For industrial and institutional buildings, that means a long service life with little maintenance.

Commercial standing seam
- New roofs and replacements on industrial, commercial and institutional buildings.
- Metal-over-metal and transition details where metal meets membrane roof sections.
- Repairs to panels, seams, trim and penetrations.
Sheet metal fabrication
Sheet metal is where roofs most often fail and where generic parts fit worst. OTC fabricates the metal its roofs need:
- Copings and edge metal sized to the wall and membrane system.
- Gutters, downspouts and scuppers sized for real drainage.
- Counterflashing, curb flashings and trim for clean, watertight transitions.
