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
