Abstract
A method of making a roofing product such as a shingle is provided. One such method includes creating a mixture having at least a polymer and a filler, forming a sheet from the mixture, cooling the sheet, embossing the sheet, forming multiple roofing products from the sheet and bundling at least some of the roofing products together. This method is performed using an automated procedure. Another method of the present invention involves creating a composite roofing product using mold cavities, using a robot to transfer some of the roofing products from some of the mold cavities to a conveying system, and stacking together at least two of the roofing products that have different colors of different surface configurations.
