1. A roofing shingle comprising:
a substrate having a first surface and an opposing second surface; and
an asphalt coating on the first surface of the substrate, wherein the asphalt coating is formed from an asphalt coating composition comprising:
20 wt. % to 80 wt. % of a filler;
20 wt. % to 50 wt. % of an asphalt base composition;
0.5 wt. % to 20 wt. % of at least one polymer additive, the at least one polymer additive comprising reclaimed rubber, based on the total weight of a non-filler portion of the asphalt coating composition; and
0.5 wt. % to 7 wt. % of a secondary additive comprising one or more of a wax, a salt of a fatty acid ester, or an amide of a fatty acid, based on the total weight of a non-filler portion of the asphalt coating composition, and;
wherein:
the non-filler portion of the asphalt coating composition has a softening point in the range of 190° F. to 240° F. and a penetration at 77° F. in the range of 15 dmm to 40 dmm;
the roofing shingle meets or surpasses the UL2218 Class 3 impact resistance standard; and
the roofing shingle is free from an integrated polymeric backing that imparts impact resistance to the roofing shingle.
