Roof having improved base sheet using metal/fabric layers with overhangs

Abstract

A roofing panel includes an insulation board and a laminate of a metal layer and a fabric layer attached to the board. The board has a quadrilateral shape defining four edges and the laminate is attached to the board such that the laminate overhangs at least two of the edges of the board. A roof is formed from a plurality of the roofing panels which are interconnected with one another such that an overhanging edge of one roofing panel overlies a non-overhanging edge of an adjacent roofing panel.

1 . A roofing panel comprising: 
 an insulation board having a quadrilateral shape defining four edges; and    a laminate of a metal layer and a fabric layer attached to said board such that said laminate overhangs at least two of the edges of said boardfabric layer faces said deck.    
   
   
       2 . The roofing panel of  claim 1 , wherein the fabric of said fabric layer is made of plastic.  
   
   
       3 . The roofing panel of  claim 2 , wherein said plastic is non-woven polyester.  
   
   
       4 . The roofing panel of  claim 1 , wherein the metal of said metal layer is aluminum.  
   
   
       5 . The roofing panel of  claim 1 , wherein the metal layer is aluminum and the fabric layer is non-woven polyester.  
   
   
       6 . The roofing panel of  claim 1 , wherein the laminate is attached to the board with the metal layer in contact with the board.  
   
   
       7 . The roofing panel of  claim 1 , wherein the laminate is attached to the board with the fabric layer in contact with the board.  
   
   
       8 . A roof comprising a plurality of roofing panels, each of the roofing panels comprising an insulation board having a quadrilateral shape defining four edges and a laminate of a metal layer and a fabric layer attached to said board such that said laminate overhangs two of the edges of said board, thereby forming a roofing panel having two overhanging edges and two non- overhanging edges, the roofing panels being interconnected with one another such that an overhanging edge of one roofing panel overlies a non-overhanging edge of an adjacent roofing panel.  
   
   
       9 . The roof of  claim 8 , wherein the fabric of said fabric layer is made of plastic.  
   
   
       10 . The roof of  claim 9 , wherein said plastic is non-woven polyester.  
   
   
       11 . The roof of  claim 8 , wherein the metal of said metal layer is aluminum.  
   
   
       12 . The roof of  claim 8 , wherein the metal layer is aluminum and the fabric layer is non-woven polyester.  
   
   
       13 . The roof of  claim 8 , wherein the laminate is attached to the board with the metal layer in contact with the board.  
   
   
       14 . The roof of  claim 8 , wherein the laminate is attached to the board with the fabric layer in contact with the board.  
   
   
       15 . A method of forming a roof on a deck comprising: 
 placing a plurality of roofing panels over said deck, each of the roofing panels comprising an insulation board having a quadrilateral shape defining four edges and a laminate of a metal layer and a fabric layer attached to said board such that said laminate overhangs two of the edges of said board, thereby forming a roofing panel having two overhanging edges and two non- overhanging edges, the roofing panels being interconnected with one another such that an overhanging edge of one roofing panel overlies a non-overhanging edge of an adjacent roofing panel. an insulating layer over said deck; and    fastening said panels to said deck.    
   
   
       16 . The method of  claim 15 , wherein the fabric of said fabric layer is made of plastic.  
   
   
       17 . The method of  claim 16 , wherein said plastic is non-woven polyester.  
   
   
       18 . The method of  claim 15 , wherein the metal of said metal layer is aluminum.  
   
   
       19 . The method of  claim 15 , wherein the metal layer is aluminum and the fabric layer is non-woven polyester.  
   
   
       20 . The method of  claim 15 , wherein the laminate is attached to the board with the metal layer in contact with the board.  
   
   
       21 . The method of  claim 15 , wherein the laminate is attached to the board with the fabric layer in contact with the board.  
   
   
       22 . The method of  claim 15 , further comprising applying a built-up roof composite over said laminate.  
   
   
       23 . The method of  claim 15 , further comprising applying a single-ply membrane over said laminate.  
   
   
       24 . The method of  claim 15 , wherein the layer of each panel on the side facing away from the deck has a plurality of different types of indicia, each type of indicia representing a different wind uplift prevention, and wherein the step of fastening said panels to said deck includes inserting fasteners through said panels at locations corresponding to the location of the types of indicia representing a desired wind uplift prevention.
