EXCEPTIONAL ® Metals History

EXCEPTIONAL ® Metals was started in response to increasing requests from contractors for a single-source manufacturer that offered a complete line of metal edge products and accessories needed to complete any single-ply roofing project.

Following Duro-Last ®’s business model of prefabricating roofing systems, EXCEPTIONAL ® Metals crafts each product to meet high-quality standards. Completed products are carefully inspected, a protective film is applied, and then they are shipped to the job site, ready for installation.
