Composite roof systems and methods of installation

摘要

A roofing system, assembly and related methods of manufacture and installation for simulating a metal roof includes a membrane which is installed over a roof deck and aesthetic ribs installed directly on the membrane layer using a hot melt adhesive having a melting temperature below the melting temperature of the membrane.

主权项

1. A composite material roof system comprising, in combination, a membrane comprised of ketone ethylene ester (KEE) reinforced with a 5.0 oz./yd2 knitted polyester fabric and heat-bonded 4 oz. polyester backing, the membrane meeting all requirements of ASTM D 6754,
a plurality of ribs attached to a surface of the membrane, the ribs formed of a polymeric material and having a cross-section configuration which includes a planar bottom with a planar bottom attachment surface and a body portion which extends generally perpendicular from the planar bottom, the body portion having a width dimension which is less than a width dimension of the planar bottom attachment surface, and a hot melt adhesive on the planar bottom attachment surface of the ribs and bonded to the ketone ethylene ester (KEE) material of the membrane.
