OneRoof™ is a Class A fire-rated, UL-certified roofing system


OneRoof® is a Class A fire-rated, UL-certified roofing system that replaces concrete roofing tiles for a fully integrated roof-plus-solar solution. And with flexible design configurations, integrated panel clips and built-in grounding, installation is simple and designed specifically for new homes.

Solar Panel roofing direct-to-deck attachments


With direct-to-deck attachments, self-aligning modules and snap-in-place module attachments, OneRoof® installs 2-3 times faster than conventional mounting. Kynar-coated metal components add a rugged layer of roof protection that lasts longer than typical composite shingles and are covered by our 25-year Complete Confidence Warranty.

OneRoof™ sits seamlessly with the rest of the roof


OneRoof® sits seamlessly with the rest of the roof for a sleek, low-profile look with virtually no visible parts. And underneath those stunning aesthetics, interlocking flashings and pans with individually sealed screws create a watertight barrier against harsh conditions— including wind-driven rain.
