PREFABRICATED MULTI-LAYER ROOFING PANEL AND SYSTEM

摘要

A prefabricated multi-layer roofing panel is utilized in a roofing system fo r low-slope roofs. The prefabricated roofing panel includes: an insulation layer that ma y have a self-adhering means on its bottom major surface for securing the roofing panel to a roofing substrate; a cover board that overlies and is bonded to the insulati on layer, and a waterproofing membrane that overlies and is bonded to the cover board. The waterproofing membrane may have waterproofing membrane overlaps for overlapping and being bonded to the waterproofing membranes of other roofing panels in t he formation of a roofing system. Preferably, the insulation layer includes interlocking structure for interlocking the prefabricated multi-layer roofing panels together in the roofing system.
