Engineered to be both economical to install and to maintain, the Butlerib® II roof offers features that make it the best through-fastened roof system in the industry. The Butlerib II system’s panels are factory cut and punched to ensure accurate endlap alignment and easy installation. Factory-slotted holes allow roof panels to expand and contract during season temperature changes, reducing roof fatigue. Corrugations standing 1 1/2″ high provide extreme durability while offering an attractive appearance.
