Claim:
A single ply roofing membrane system comprising: a roof deck; and a recyclable, reinforced membrane overlaying the roof deck; the membrane having first and second propylene-ethylene-copolymer sheets polymerized from a polypropylene and ethylene-monomer blend comprising about 30% to about 70% by weight polypropylene and about 30% to about 70% by weight ethylene-monomer and a hydrophobic polypropylene reinforcing mesh intermediate the first and second propylene-ethylene-copolymer sheets and bonded to the first and second propylene-ethylene-copolymer sheets for reinforcing the membrane; the polypropylene reinforcing mesh being chemically compatible with the first and second propylene-ethylene-copolymer sheets for permitting scrap produced in a process of manufacturing the membrane to be recycled back into the process.
