A roofing system comprising:
- a roof substrate;
- and
- at least one roofing shingle located on the roof substrate, wherein the at least one roofing shingle comprises:
- a substrate,
- wherein the substrate has a top surface and a bottom surface;
- a first asphalt shingle waste coating,
- wherein the first asphalt shingle waste coating is located on at least a portion of the top surface of the substrate,
- wherein the first asphalt shingle waste coating comprises a first asphalt shingle waste;
- wherein the first asphalt shingle waste comprises a waste asphalt and limestone;
- a second asphalt shingle waste coating,
- wherein the second asphalt shingle waste coating is located on at least a portion of the bottom surface of the substrate;
- wherein the second asphalt shingle waste coating comprises a second asphalt shingle waste;
- wherein the second asphalt shingle waste coating contacts the roof substrate;
- and
- an asphalt coating,
- wherein the asphalt coating is located on at least a portion of the first asphalt shingle waste coating,
