The Garland Co. Inc. has upgraded its R-Mer Edge fascia and coping systems for low-slope roofing. The systems are certified to conform to ANSI/SPRI ES-1, which formalizes the International Building Code specifications for resistance to wind-related failures. Performance improvements include a streamlined cant dam profile for R-Mer fascia, improved geometry on the inside leg of R-Mer Edge coping and elimination of exposed fasteners that can back out and create leaks.
