Abstract
A mount for a membrane roof is assembled from first and second metal plates coated on at least one side with heat-weldable material, at least one bolt and two sheets of membrane roofing material. The parts are assembled in a manner that the bolt faces upwards and is effectively sealed in the assembly against any leak around the bolt by a first sheet of roofing material. The mount may be attached to a roof by fasteners around the periphery of the first base plate, and the second sheet of membrane material seals the fasteners and fastener holes.
Claims20
A mounting assembly for a membrane roof, comprising:
- a first metal base plate coated on an upper surface with material compatible to heat weld to roofing membrane material, having length and width dimensions, and having a plurality of openings spaced around an outer periphery;
- a second metal base plate coated on at least an upper surface with membrane material and having length and width dimensions substantially smaller than the first metal base plate, and a substantially centered through opening;
- a bolt having a length, a head diameter larger than the diameter of the through opening in the second base plate and a threaded portion of a diameter to pass through the through opening;
- and
- a first sheet of roofing membrane material having length and width dimensions substantially larger than those of the second base plate and substantially smaller than those of the first base plate, the sheet of roofing membrane having a substantially centered through opening;
- wherein the bolt is passed through the through opening in the second metal base plate from below, the second metal base plate with the bolt is centered over and adhered by welding or adhesive to the first metal base plate, and the first sheet of roofing membrane material is assembled over the threaded portion of the bolt and heat welded to the membrane coatings on both the first and the second metal base plates, leaving the plurality of openings spaced around the outer periphery of the first base plate exposed, providing an assembly ready to be mounted to a membrane roof.

A method for providing a mounting bolt on a membrane roof, comprising steps:
- forming a first metal base plate coated on an upper surface with a material compatible with heat welding to roofing membrane, the first metal base plate having length and width dimensions, and having a plurality of openings spaced around an outer periphery;
- forming a second metal base plate coated on an upper surface with the material compatible with heat welding to roofing membrane, the second metal base plate having length and width dimensions substantially smaller than the first metal base plate and a substantially centered through opening;
- passing a bolt having a head larger than the through opening upward through the centered through opening of the second base plate;
- joining the second base plate to the first base plate by welding or adhesive, substantially centered on the first base plate;
- forming a first sheet of roofing membrane material having length and width dimensions substantially larger than those of the second base plate and substantially smaller than those of the first base plate and the pattern of openings around the periphery of the first metal base plate, and having a substantially centered through opening;
- and
- placing the first sheet of roofing membrane over the second base plate with the bolt through the through hole, and heat welding the first sheet of roofing membrane to both the second base plate and the first base plate, forming a mount assembly leaving the plurality of openings around the outer periphery of the first base plate uncovered.

A mounting assembly for a membrane roof, comprising:
- a metal base plate coated on both sides with material compatible to heat weld to roofing membrane material, having length and width dimensions, having a plurality of openings spaced around an outer periphery, and having at least one hole through the base plate within the pattern of openings around the outer periphery;
- a bolt having a length, a head diameter larger than the diameter of the at least one hole and a threaded portion of a diameter to pass through the at least one hole;
- and
- a sheet of roofing membrane material having length and width dimensions smaller than those of the first base plate;
- wherein the bolt is passed through the at least one hole in the metal base plate from one side with the head of the bolt welded or otherwise adhered to the metal base plate, and the sheet of roofing membrane is positioned over the head of the bolt and heat welded to the heat-weld compatible material on the base plate.
