Integrated roof system with integrated driplap edge

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, and a driplap edge along the bottom edge of the base layer. A texturizing material also may be affixed to, or integrated with, the water resistant barrier layer.

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 
 texturizing material covering or integrated with the water resistant barrier layer; 
   wherein the bottom edge comprises a angled bottom face.   
     
     
         2 . The product of  claim 1 , wherein angled bottom face is at an acute angle with respect to the top edge. 
     
     
         3 . The product of  claim 1 , wherein the acute angle is approximately 25 degrees. 
     
     
         4 . The product of  claim 1 , wherein the acute angle is 25 degrees. 
     
     
         5 . The product of  claim 1 , wherein the acute angle is in the range of approximately 23 degrees to approximately 27 degrees. 
     
     
         6 . The product of  claim 1 , further comprising one or more flashing pieces extended outward from one or more edges of the roofing panel or plank. 
     
     
         7 . The product of  claim 1 , wherein the texturizing material comprises one or more of: ceramic coated granules, rock, glass, slate, rubber, plastic, or a synthetic polymer. 
     
     
         8 . The product of  claim 1 , wherein the upper edge comprises an underlap portion of a shiplap joint. 
     
     
         9 . The product of  claim 8 , 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. 
     
     
         10 . The product of  claim 1 , wherein the water resistant barrier layer comprises a polymer. 
     
     
         11 . The product of  claim 6 , wherein the one or more flashing pieces comprises a polymer. 
     
     
         12 . The product of  claim 6 , wherein the one or more flashing pieces is integrated with the base layer or the water resistant barrier layer. 
     
     
         13 . The product of  claim 6 , wherein the one or more flashing pieces comprises a flexible polymer configured to be molded during installation to a structure to be flashed. 
     
     
         14 . 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. 
     
     
         15 . 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;   milling, in a processing line at a manufacturing facility, an acute angled face in the bottom edge.
