A method to produce a veneer element, including defects and dense portions. The method includes providing a substrate, providing a sub-layer, including a binder and coloured filler particles, applying the sub-layer on a first surface of the substrate, applying a veneer layer on the sub-layer, and applying pressure, preferably heat and pressure, to the veneer layer and/or the substrate, thereby forming a veneer element wherein, after pressing, the sub-layer is visible through a defect of the veneer element such as crack, cavity, hole and/or knot of the veneer layer. Also, a veneer element.

A process for in-line extrusion of polymeric coatings onto roofing shingles during manufacturing includes moving a web of shingle substrate material in a downstream direction and extruding a liquefied coating of polymeric material onto at least one surface of the moving web to form a thin film. The liquefied coating may be a molten polymeric material that forms a thin film on a back surface of the shingle material to prevent sticking and eliminate the need for a traditional back dusting with material such as powdered stone. The polymeric film further may be applied to the substrate material in lieu of a saturation coating of asphalt, thus reducing cost and weight while providing a comparable moisture barrier and a lighter more flexible shingle.
