Ondura® Premium Roofing Panel can be installed over open purlins, solid decking, or existing shingles or metal roofing. It resists high winds and is much quieter than metal roofing. These panels use advancements in resins and painting technology to enhance the pigment/paint process throughout the product, not just a surface coating. The panels are an environmentally preferable product, made from 50% recycled material. They feature a 3-inch overlap and cover 17.94 square feet. These panels are also backed with a Lifetime Limited Warranty.
