Abstract: A method to manufacture, on one or more production or manufacturing lines, an integrated roofing product, such as a roofing panel or roofing plank. A blank panel of engineered wood is cut or sawn into a plurality of raw planks or raw panels, each with an outer face, an inner face, a top edge, and a bottom edge. Each raw plank or panel is then processed by cutting or routing a profile into the top edge, the bottom edge, or both; affixing a gasket seal to the profile in the top edge or the bottom edge, or both; coating at least some or all of the outer face with a silicone-based or silicone -containing coating; applying a mix of granules and/or sand to the silicone-based coating while wet; and curing the coated plank or panel. A plurality of such panels or planks can then be shipped and installed on a roofing structure.
