Colonial Seam

The Colonial Seam® panel is a clipless, one-piece, positive-locking, standing seam panel that provides a timeless roof appearance. Installation is accomplished by hooking the panel into the previous panel and fastening with mechanical fasteners through pre-punched slots to allow for expansion and contraction. The fasteners are covered by the adjacent panel. The positive locking action makes it virtually impossible for the panels to slide apart.
