Abstract

Hybrid roof cover systems comprise a metal panel field and a membrane field joined by metal standing seam transition roof panels. The metal transition panel comprises an upstanding side, a planar portion, and a polymer layer. The upstanding side defines a first lateral edge of the metal transition panel. The first lateral edge is symmetrical with a lateral edge of an adjacent roof panel in the metal panel field. The first lateral edge is adapted to form a sidelap between the metal transition panel and the adjacent roof panel in the metal panel field. The planar portion extends from the first lateral edge to a second lateral edge of the metal transition panel. The polymer layer is bonded to an upper face of the planar portion of the metal transition panel and is adapted to bond to the membrane sheet in the membrane field of the hybrid roof cover system.
