Zusammenfassung:An asphalt coated roofing shingle including a mat substrate saturated with asphalt, a top asphalt layer on a top surface of the mat, a bottom asphalt layer on a bottom surface of the mat, a granular layer on the top asphalt layer and a layer of melt-blown fibers applied to the bottom asphalt layer. A method for making a lightweight roofing shingle including the steps of saturating a mat substrate wherein the mat substrate has a top surface and a bottom surface; applying a top asphalt layer to the top surface; applying a bottom asphalt layer to the bottom surface; applying a layer of granular material to the top asphalt layer opposite the mat after the top asphalt layer is applied to the top surface; and applying a layer of melt-blown fibers directly to the bottom asphalt layer after the bottom asphalt layer is applied to the mat substrate.
