Method and article of manufacture for sealing a roof

Abstract

A process of pre-applying a vapor, water and ice layer to a sheathing panel before the sheathing panel is assembled onto rafters of a roof is disclosed, comprising the steps of positioning a face of the sheathing panel for accessibility, removing a plastic film from the vapor, water and ice layer, thereby exposing an adhesive surface of the vapor, water and ice layer, joining the adhesive surface of the vapor, and water and ice layer to the face of the sheathing panel to form an assembly, thereafter, transporting the assembly to the roof, and securing the assembly to the rafters of the roof. An article of manufacture for reducing water and ice damage caused by an ice dam on a roof is disclosed, wherein the article of manufacture is pre-assembled prior to assembly to rafters of the roof, comprising a sheathing panel for assembling on the rafters of the roof having a first face and a second face, a vapor, water and ice layer having a first side and a second side, the second side having a plastic film covering an adhesive backing, means for removing the plastic film to expose the adhesive backing and means for assembling the vapor, water and ice layer to the sheathing panel, wherein the second side of the vapor, water and ice layer having the adhesive backing is placed onto the first face of sheathing panel before assembly of the sheathing panel to the rafters of the roof.

1 . A roofing panel for a roof having a plurality of roof rafters, comprising: 
 a sheathing panel having a face;    a vapor, water, or ice resistant layer to said face;    said sheathing panel and    said resistant layer being fixed together before being attached to the roof rafters, thereby comprising a modular roof panel.    
   
   
       2 . The roof panel according to  claim 1 , wherein said vapor, water, and ice resistant layer is attached to said sheathing panel with an adhesive.  
   
   
       3 . The roof panel according to  claim 1 , wherein said vapor, water, and ice resistant layer is sprayed onto said sheathing panel.  
   
   
       4 . The roof panel according to  claim 1 , wherein said vapor, water, and ice resistant layer is formed on said sheathing panel by dipping said sheathing panel into a dip tank containing said vapor, water, and ice resistant layer.  
   
   
       5 . The roof panel according to  claim 1 , wherein said vapor, water, and ice resistant layer covers at least three-fourths of said sheathing panel.  
   
   
       6 . The roof panel according to  claim 1 , wherein said sheathing panel is nailed to said at least one of the plurality of roof rafters.  
   
   
       7 . The roofing panel of  claim 1  wherein said resistant layer seals around nails used to secure said panel to the rafters.  
   
   
       8 . The roofing panel of  claim 1  wherein said roofing panel is plywood.  
   
   
       9 . The roofing panel of  claim 1  wherein said panel is dimensioned to be adjacent to an eave of a roof.  
   
   
       10 . The roofing panel of  claim 1  having four edges, said resistant layer being further attached to at least one of said edges.  
   
   
       11 . The roofing panel of  claim 1  wherein said resistant layer extends beyond an edge of said sheathing panel.  
   
   
       12 . The roofing panel of  claim 1  further comprising tape for sealing a joint between said roofing panel and an adjacent panel in assembly.  
   
   
       13 . The roofing panel of  claim 1  wherein said resistant layer is underneath said sheathing panel.
