TL;DR
R-panel metal roofing is an exposed-fastener steel panel with trapezoidal ribs about 1.25 inches tall on 12-inch centers, covering 36 inches of width per sheet—a commodity profile borrowed from metal buildings and popular on shops, barns, and budget residential reroofs. Panels screw directly through the flat into purlins or decking with gasketed fasteners that need retightening or replacement over the years.
What it means
R-panel metal roofing is an exposed-fastener steel panel with trapezoidal ribs about 1.25 inches tall on 12-inch centers, covering 36 inches of width per sheet—a commodity profile borrowed from metal buildings and popular on shops, barns, and budget residential reroofs. Panels screw directly through the flat into purlins or decking with gasketed fasteners that need retightening or replacement over the years. It costs notably less than standing seam but trades away the concealed-fastener longevity.
