Roof Seam Fastener System

Abstract

A roof seam fastener system including a mechanical fastener member for mechanically attaching a roof membrane to a roof structure. The roof seam fastener system comprises a fastening assembly that creates a seal to either the roof membrane or a roofing substrate located directly below the fastening assembly. This fastening assembly also creates a seal against the mechanical fastener member. This combination results in redundancy which prevents any water penetration into the seam from entering the roofing envelope. The roof seam fastener system improves wind uplift resistance of the roof membrane and minimizes other weather related damage.

1 . A roof seam fastener system including a fastener member for attaching a roof membrane to a roof structure, said roof seam fastener system comprising:
 a fastening assembly that creates a seal to one of a roof membrane and a substrate located directly below said fastening assembly and wherein said fastening assembly further creates a seal against such fastener member.   
   
   
       2 . The system as recited in  claim 1  wherein said fastening assembly comprises a clamping plate having at least one washer laminated on one or both sides thereof and such fastener member includes a shaft extending through said clamping device and said at least one washer. 
   
   
       3 . The system as recited in  claim 2  wherein said clamping plate is formed from one of a metal or plastic material and said washer is formed from one of a flexible or compressible material. 
   
   
       4 . The system as recited in  claim 2  wherein said clamping plate is formed from one of a metal or plastic material and said washer is formed from one of a rubber or plastic washer. 
   
   
       5 . The system as recited in  claim 2  wherein said washer is laminated onto said clamping plate by one of welding, fusing, brazing, and adhesively bonding. 
   
   
       6 . The system as recited in  claim 2  wherein said fastening assembly is sealed to a top surface of said roof membrane. 
   
   
       7 . The system as recited in  claim 2  wherein said fastening assembly is sealed between said substrate and said roof membrane. 
   
   
       8 . The system as recited in  claim 2  wherein said at least one washer includes an aperture preformed therein for allowing said shaft of said fastening member to extend therethrough. 
   
   
       9 . The system as recited in  claim 2  wherein said at least one washer comprises a solid member and said shaft of said fastening member penetrates said solid member during installation of said fastening system. 
   
   
       10 . The system as recited in  claim 2  wherein said at least one washer has a first aperture extending therethrough and having a first diameter and said clamping plate has a second aperture having a second diameter and extending therethrough in alignment with said first aperture, and wherein said first diameter is less than second diameter to facilitate sealing of said at least one washer to said fastening member upon insertion of said fastening member through said first and second apertures. 
   
   
       11 . The system as recited in  claim 1  wherein said fastening assembly comprises a clamping plate and a joining material positioned adjacent to said clamping plate. 
   
   
       12 . The system as recited in  claim 11  wherein said joining material comprises a field applied sealant or adhesive material. 
   
   
       13 . The system as recited in  claim 11  wherein said fastening assembly includes a fastening member having a shaft extending through said clamping device and said joining material. 
   
   
       14 . The system as recited in  claim 2  wherein said fastening assembly comprises a clamping plate having a washer laminated thereto and a joining material positioned adjacent to said washer. 
   
   
       15 . The system as recited in  claim 14  wherein said joining material comprises a field applied sealant or adhesive material. 
   
   
       16 . The system as recited in  claim 15  wherein said fastening assembly includes a fastening member having a shaft extending through said clamping device and said joining material.
