Method of reroofing

Abstract

A method of reroofing, the method comprising of applying to an existing roof surface a membrane composite including a pre-applied adhesive layer by mating the adhesive layer to the existing membrane.

1 - 6 . (canceled) 
     
     
         7 . A method of reroofing an existing roof system including an existing membrane, the method comprising:
 (i) providing a membrane composite, where the composite includes a polymeric membrane and an adhesive layer disposed on a planar surface of the membrane, the adhesive layer being applied to the membrane as a hot-melt adhesive and being at least partially cured by UV radiation, the composite further comprising a release member removably attached to the adhesive layer;   (ii) removing debris from the existing membrane;   (iii) after said step of removing debris, washing the existing membrane;   (iv) removing the release member from said composite; and   (v) adhering the composite to the existing membrane by mating the adhesive layer to the membrane.   
     
     
         8 . The method of  claim 7 , where the adhesive layer includes a polyacrylate adhesive. 
     
     
         9 . The method of  claim 8 , where said step of removing debris includes blowing the debris with a power blower. 
     
     
         10 . The method of  claim 9 , where said step of washing includes applying water and a cleaning solution. 
     
     
         11 . The method of  claim 7 , where said step of adhering the composite to the existing membrane creates a bond having a peel strength, as determined by PSTC 101, of at least 3.0 pli. 
     
     
         12 . The method of  claim 7 , where said step of adhering the composite to the existing membrane creates a bond having a peel strength, as determined by PSTC 101, of at least 3.5 pli. 
     
     
         13 . The method of  claim 7 , where said step of adhering the composite to the existing membrane creates a bond having a dead load shear, as determined by PSTC 107, of at least 0.5 hour. 
     
     
         14 . The method of  claim 7 , where said step of adhering the composite to the existing membrane creates a bond having a dead load shear, as determined by PSTC 107, of at least 1.0 hour. 
     
     
         15 . The method of  claim 7 , where said membrane of said composite is an EPDM membrane. 
     
     
         16 . The method of  claim 7 , where said membrane of said composite is a TPO membrane. 
     
     
         17 . The method of  claim 7 , where said existing membrane is an EPDM membrane. 
     
     
         18 . The method of  claim 7 , where said existing membrane is a TPO membrane.
