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.

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.
Claims19
An integrated roofing product, comprising:
- a multilayered, integrated roofing panel or plank, comprising:
- a base layer comprising an engineered wood sheathing panel, the base layer comprising an outer face, a top edge, a bottom edge, a left edge, and a right edge, wherein at least one of the top edge and the bottom edge comprise an overlap portion or underlap portion of a shiplap joint;
- a water resistant barrier layer covering at least the outer face of the base layer, and at least one of the edges;
- and
- a roof surface layer affixed to or forming a surface of the water resistant barrier layer, said roof surface layer further comprising a texturizing material;
- wherein the integrated roofing product is configured as one multi-layer panel product combining a structural sheathing panel, a water resistant barrier, and a roof surface layer that eliminates separate sequential application during installation thereof;
- wherein the upper edge comprises the underlap portion of said shiplap joint;
- wherein the underlap portion comprises an underlap joint face parallel to the outer face with an underlap lip orthogonal to the underlap joint face extending between the underlap joint face and the outer face;
- and
- further comprising one or more water evacuation channels extending from the underlap lip partway down the outer face towards the bottom edge, each of said one or more water evacuation channels having a gradually decreasing depth, with the greatest depth at the underlap lip.
