Patent ID: 8322101

Claim:
A method for anchoring a roof seam, the method comprising: providing a roof substrate that includes a corrugated roof deck and roof assembly components disposed upwardly adjacent of said rood deck; laying a first waterproofing membrane over said roof assembly components; laying a portion of a second waterproofing membrane over said roofing assembly components, laying an overlap portion of said second waterproofing membrane over an overlapped portion of said first waterproofing membrane; creating a seam region between said first waterproofing membrane and said second waterproofing membrane via said laying of said overlap portion over said overlapped portion; laying a sealing substrate over said overlap portion of said second waterproofing membrane disposing a metal termination bar upwardly adjacent of said sealing substrate in said seam region, said termination bar including metal legs extending obliquely from a central portion towards said roof deck, and said metal legs defining a bar cavity including a greater width than a combined width of said legs; positioning said termination bar being directly over an upwardly extending corrugation of said corrugated roof deck and anchoring said first membrane to said second membrane, and anchoring said seam region to said roof deck, via a mechanical fastener extending through said termination bar, said mechanical fastener being long enough to extend from said termination bar, through said seam region and said roof assembly components, and into said upwardly extending corrugation of said corrugated roof deck, and said mechanical fastener compressing said metal termination bar and sealant substrate such that said sealant substrate is deformed in a direction of said second membrane at areas of contact between said metal legs of said metal termination bar and said sealant substrate, and a remaining non-deformed portion of said sealant substrate nests within said bar cavity, said non-deformed portion of said sealant structure including a greater width than a combined width of said areas of contact that are deformed.
