1. A method for generating a shingle roof coating comprising:
receiving an asphalt feedstock;
mixing an elastomeric polymer and an asphalt flux to generate a concentrate, wherein the elastomeric polymer includes ethylene bis-stearamide (EBS) and trisodium phosphate maltene (TSP), wherein the concentrate comprises 5% by weight to 40% by weight of the EBS and 1% by weight to 15% by weight of the TSP;
heating the first concentrate separately from the asphalt feedstock;
heating the combined concentrate and the asphalt feedstock to generate the shingle roof coating; and
wherein the amount of elastomeric polymer in the resulting shingle roof coating includes 0.5% to 6% by weight of the elastomeric polymer.
