Fully-adhered roof system adhered and seamed with a common adhesive

Abstract

A roof system comprising a roof substrate, a first membrane including first and second opposed planar surfaces, and a second membrane including opposed first and second planar surfaces, where said second membrane is adhered to said roof substrate through an adhesive disposed on said roof-substrate contacting portion of the first membrane, and where said second membrane is adhered to said first membrane through said adhesive disposed on a lap portion of said second membrane.

1 . A roof system comprising:
 i. a roof substrate;   ii. a first membrane including first and second opposed planar surfaces, where the first planar surface includes a roof-substrate contacting portion and a lap portion, said membrane having disposed on said roof-substrate contacting portion and said lap portion a UV-cured adhesive, where said first membrane is adhered to said roof substrate through said adhesive disposed on said roof-substrate contacting portion; and   iii. a second membrane including opposed first and second planar surfaces, where the first planar surface includes a roof-substrate contacting portion and a lap portion, said membrane having disposed on said roof-substrate contacting portion and said lap portion a UV-cured adhesive, where said second membrane is adhered to said roof substrate through said adhesive disposed on said roof-substrate contacting portion, and where said second membrane is adhered to said first membrane through said adhesive disposed on said lap portion of said second membrane, where said UV-cured adhesive disposed on said roof-substrate portion and said lap portion is substantially homogeneous.   
     
     
         2 . (canceled) 
     
     
         3 . The roof system of  claim 1 , where said first membrane and said second membrane are thermoplastic polyolefin membranes. 
     
     
         4 . The roof system of  claim 1 , where said first membrane and said second membrane are cured EPDM membranes. 
     
     
         5 . The roof system of  claim 1 , where said UV-cured adhesive is a polyacrylate adhesive. 
     
     
         6 . A method of installing a roof system, the method comprising:
 i. providing a membrane composite including a polymeric planar body having first and second opposed planar surfaces, where said first planar surface includes a roof-substrate contracting portion and a lap portion, a UV-cured adhesive layer disposed on the roof-substrate contacting portion and the lap portion, and a release member removably affixed to the adhesive layer;   ii. adhesively securing said membrane composite to a roof surface through the UV-cured adhesive;   iii. providing a second membrane composite including a polymeric planar body having first and second planar surfaces, where said first planar surface includes a roof-substrate contracting portion and a lap portion. a UV-cured adhesive layer disposed on the roof-substrate contacting portion and the lap portion, and a release member removable fixed to the adhesive layer;   iv. adhesively securing the second membrane composite to the roof surface through the UV-cured adhesive, where the second membrane composite in positioned adjacent to and partially overlapping the first membrane composite so as to form a seam area; and   v. adhesively securing the second membrane composite to the second planar surface of the first membrane composite within said [[lap]] seam area through said UV-cured adhesive disposed on the second membrane composite,   where said UV-cured adhesive disposed on said roof-substrate portion and said lap portion is substantially homogeneous .   
     
     
         7 . A membrane composite comprising:
 i. a membrane panel having opposed first and second planar surfaces, said first planar surface including a roof-substrate contacting portion and a lap portion;   ii. a UV-cured adhesive disposed on said roof-substrate contacting portion and said lap portion; and   iii. a release member removable affixed to said UV-cured adhesive in both said roof-substrate contacting portion and said lap portion, where said UV-cured adhesive disposed on said roof-substrate portion and said lap portion is substantially homogeneous.   
     
     
         8 . The membrane of  claim 7 , where said release member includes a perforation that allows said release member to be divided between said roof-substrate contacting portion and said lap portion. 
     
     
         9 . The membrane of  claim 1 , where the degree of cure of said UV-cured adhesive is substantially consistent between said roof-substrate contacting portion and said lap portion. 
     
     
         10 . The membrane of  claim 1 , where the degree of cure of said UV-cured adhesive varies by no more than 10% between said non-substrate contacting portion and said lap portion. 
     
     
         11 . The membrane of  claim 1 , where the degree of cure of said UV-cured adhesive varies by no more than 1% between said non-substrate contacting portion and said lap portion. 
     
     
         12 . The membrane of  claim 6 , where the degree of cure of said UV-cured adhesive is substantially consistent between said roof-substrate contacting portion and said lap portion. 
     
     
         13 . The membrane of  claim 6 , where the degree of cure of said UV-cured adhesive varies by no more than 10% between said non-substrate contacting portion and said lap portion. 
     
     
         14 . The membrane of  claim 6 , where the degree of cure of said UV-cured adhesive varies by no more than 1% between said non-substrate contacting portion and said lap portion. 
     
     
         15 . The membrane of  claim 7 , where the degree of cure of said UV-cured adhesive is substantially consistent between said roof-substrate contacting portion and said lap portion. 
     
     
         16 . The membrane of  claim 7 , where the degree of cure of said UV-cured adhesive varies by no more than 10% between said non-substrate contacting portion and said lap portion. 
     
     
         17 . The membrane of  claim 7 , where the degree of cure of said UV-cured adhesive varies by no more than 1% between said non-substrate contacting portion and said lap portion.
