A roofing material comprises a substrate having an exposed surface and an unexposed surface. An asphalt shingle waste coating is located on at least a portion of the exposed surface of the substrate. The asphalt shingle waste coating comprises an asphalt shingle waste, wherein the asphalt shingle waste comprises a waste asphalt and a limestone. An asphalt sealcoat is located on at least a portion of the asphalt shingle waste coating. The asphalt sealcoat is substantially free of the asphalt shingle waste. The asphalt sealcoat has a thickness of no greater than 50% of a thickness of the asphalt shingle waste coating. ## Claims ### Claim 1 A roofing shingle comprising: a substrate, wherein the substrate has an exposed surface and an unexposed surface; an asphalt shingle waste coating, wherein the asphalt shingle waste coating is located on at least a portion of the exposed surface of the substrate, wherein the asphalt shingle waste coating comprises an asphalt shingle waste, wherein the asphalt shingle waste comprises a waste asphalt and a limestone; and an asphalt sealcoat, wherein the asphalt sealcoat is located on at least a portion of the asphalt shingle waste coating, wherein the asphalt sealcoat is substantially free of the asphalt shingle waste, wherein the asphalt sealcoat has a thickness of no greater than 50% of a thickness of the asphalt shingle waste coating. ### Claim 2 (depends on 1) The roofing shingle of claim 1, wherein the asphalt shingle waste coating directly contacts the exposed surface of the substrate. ### Claim 3 (depends on 1) The roofing shingle of claim 1, wherein the asphalt shingle waste coating covers 50% to 99% of the exposed surface of the substrate. ### Claim 4 (depends on 1) The roofing shingle of claim 1, wherein the asphalt shingle waste coating covers an entire exposed surface of the substrate. ### Claim 5 (depends on 1) The roofing shingle of claim 1, wherein the asphalt sealcoat directly contacts the asphalt shingle waste coating. ### Claim 6 (depends on 1) The roofing shingle of claim 1, wherein the asphalt sealcoat covers 50% to 99% of the asphalt shingle waste coating. ### Claim 7 (depends on 1) The roofing shingle of claim 1, wherein the asphalt sealcoat covers an entire surface of the asphalt shingle waste coating. ### Claim 8 (depends on 1) The roofing shingle of claim 1, wherein the asphalt sealcoat is free of asphalt shingle waste. ### Claim 9 (depends on 1) The roofing shingle of claim 1, wherein the thickness of the asphalt sealcoat is 5% to 50% of the thickness of the asphalt shingle waste coating. ### Claim 10 (depends on 1) The roofing shingle of claim 1, wherein the thickness of the asphalt sealcoat is 5% to 40% of a thickness of the asphalt shingle waste coating. ### Claim 11 (depends on 1) The roofing shingle of claim 1, wherein the thickness of the asphalt sealcoat is 5% to 30% of a thickness of the asphalt shingle waste coating. ### Claim 12 (depends on 1) The roofing shingle of claim 1, wherein the thickness of the asphalt sealcoat is 5% to 20% of a thickness of the asphalt shingle waste coating. ### Claim 13 (depends on 1) The roofing shingle of claim 1, wherein the thickness of the asphalt sealcoat is 0.1 mils to 100 mils;
