LOCATION: Bluffton, SC
ARCHITECT: Greg Beste Architects
GENERAL CONTRACTOR: Hill Construction Corp.
CONTRACTOR: Southern Roof & Wood Care Corp.
MATERIALS: UNA-CLAD^® UC-1 Snap-On Standing Seam, 24 gauge Steel, Hylar 5000^™/Kynar 500^® finish by Valspar

The UNA-CLAD^® UC-1 is a Snap-On Standing Seam roofing system that allows a distinctly different look to enhance the architect’s design while meeting current wind-load design for architectural metal roofing. Concealed fasteners and hold-down clips allow for freedom of movement for general expansion and contraction. It is recommended that UC-1 panels be installed over a solid substrate such as plywood and an underlayment of 30# felt. Panels for mansard or canopy installations may utilize open framing systems. The UC-1 roofing system is available in 22, 24, 26 gauge painted galvanized steel, .032 and .040 painted and anodized aluminum, and 16 oz. and 20 oz. Architectural Grade Sheet Copper. Heavier gauges, narrower widths, and embossing minimize oil canning.

Note: Oil canning is not a cause for rejection.
