Patent ID: 7935202

Claim:
A system, comprising: a first thermoplastic membrane having: a top surface; and a bottom surface, the bottom surface being attached to a portion of a roof structure; a mounting plate having a bottom surface; a second thermoplastic polymeric membrane consisting of polyvinyl chloride, the second thermoplastic polymeric membrane having: an upper surface, the upper surface being thermally bonded to the bottom surface of the mounting plate; and a lower surface having: a first surface area, the first surface area extending peripherally along a perimeter of the lower surface, the first surface area being thermally fused to the top surface area of the first membrane; and a second surface area, the second surface area being enclosed within the first surface area, the second surface area being positioned below the mounting plate, the second surface area remaining separable from the first membrane as a force is exerted against the mounting plate; and a protrusion attached to the mounting plate, the protrusion extending in a direction opposite to the roof structure.
