A roofing system and construction wherein a waterproof membrane consisting of an impervious base sheet being applied directly to the surface of a roof deck. The waterproof membrane is a heavy duty material having a high strength heat resistant mesh throughout and integral in the membrane. This base sheet membrane has a bottom surface of self-adhesive rubberized material and, upon application of the base sheet membrane to the roof deck, results in a permanent bond between the roof deck and the base sheet membrane. An insulation layer of sprayed insulating foam is applied directly to the top of the base sheet membrane and the chemical composition of the spray foam and the chemical composition of the base sheet upper surface further provides for a permanent and continuing bond therebetween upon the application of said insulating foam.
