Overview

Meet the Grip-Rite SL154250LWE synthetic roofing underlayment, a lightweight yet durable layer designed for use during roof installation. With dimensions of 48 inches wide by 250 feet long, this roll covers substantial area in a single piece, reducing seams and simplifying handling on busy job sites.
