R-Mer Span is a structural standing seam roof system. R-Mer Span consists of a unique profile containing mesas throughout the panel to minimize “oil canning.” The 2 3/8” high vertical seam makes R-Mer Span aesthetically pleasing and the ideal roof system to withstand severe weather conditions. The heavy-duty continuous clip allows for unlimited expansion and contraction. R-Mer Span can be used on slopes down to 1/4” per foot for retrofit and/or new construction.
