Integrated ventilation and flashing in integrated roof system with engineered wood

Abstract

A multi-layered integrated roofing plank or panel with a base layer comprising engineered or manufactured wood, a water resistant barrier layer covering at least the outer face of the base layer, and at least one of the edges of the base layer. A texturizing material also may be affixed to, or integrated with, the water resistant barrier layer. The edges of the roofing plank or panel may be configured as part of a joint with adjacent planks or panels, including, but not limited to, shiplap joints, tongue-and-groove joints, bead-and-cove joints, butt joints, or combinations or variations thereof.

What is claimed is: 
     
         1 . An integrated roofing product, comprising:
 a roofing panel or plank, comprising:
 a base layer comprising engineered wood, the base layer comprising an outer face, a top edge, a bottom edge, a left edge, and a right edge; 
 a water resistant barrier layer covering at least the outer face of the base layer, and at least one of the edges; and 
 one or more flashing pieces extended outward from one or more edges of the roofing panel or plank. 
   
     
     
         2 . The product of  claim 1 , further comprising texturizing material covering or integrated with the water resistant barrier layer, wherein the texturizing material comprises one or more of: ceramic coated granules, rock, glass, slate, rubber, plastic, or a synthetic polymer. 
     
     
         3 . The product of  claim 1 , wherein the water resistant barrier layer covers the top edge and the bottom edge. 
     
     
         4 . The product of  claim 1 , wherein the upper edge comprises an underlap portion of a shiplap joint, and the bottom edge comprises an overlap portion of a shiplap joint. 
     
     
         5 . The product of  claim 5 , wherein the underlap portion comprises an underlap joint face parallel to the outer face, and the underlap joint face is covered at least in part by the water resistant barrier layer. 
     
     
         6 . The product of  claim 1 , wherein the water resistant barrier layer comprises a polymer. 
     
     
         7 . The product of  claim 1 , wherein the flashing comprises a polymer. 
     
     
         8 . The product of  claim 1 , wherein the flashing is integrated with the base layer or the water resistant barrier layer. 
     
     
         9 . The product of  claim 4 , wherein the flashing extends from the overlap portion and over said shiplap joint. 
     
     
         10 . The product of  claim 1 , wherein the flashing is the same color as an outward facing surface of the roofing panel or plank. 
     
     
         11 . The product of  claim 1 , wherein the flashing extends straight outward in a plane. 
     
     
         12 . The product of  claim 1 , wherein the flashing is bent or folded one or more times. 
     
     
         13 . The product of  claim 1 , wherein the flashing comprises a flexible polymer configured to be molded during installation to a structure to be flashed. 
     
     
         14 . The product of  claim 1 , further comprising one or more vents extending through the roofing panel or plank. 
     
     
         15 . The product of  claim 14 , wherein the one or more vents are located proximate the top edge. 
     
     
         16 . The product of  claim 1 , wherein the flashing is integrated with the roofing panel or plank in a processing line at a manufacturing facility, prior to installation on a structure. 
     
     
         17 . The product of  claim 14 , wherein the one or more vents are integrated with the roofing panel or plank in a processing line at a manufacturing facility, prior to installation on a structure 
     
     
         18 . A method of producing the integrated roofing product of  claim 1 , comprising:
 providing a base layer with an outer face, a top edge, a bottom edge, a right edge, and a left edge, said base layer comprising engineered wood;   applying, in a processing line at a manufacturing facility, a fluid-applied or liquid-applied membrane to the outer face of the base layer, and to at least one edge of the base layer;   affixing, in a processing line at a manufacturing facility, one or more pieces of flashing extending outward from one or more edges of the base layer.   
     
     
         19 . The method of  claim 18 , further comprising:
 installing, in a processing line at a manufacturing facility, one or more vents extending through the base layer and membrane.
