Abstract
A method for generating a shingle roofing coating is described. The method includes mixing 1% by weight to 20% by weight of an elastomeric polymer with an asphalt flux to generate a concentrate. The concentrate is then heated and mixed with an oxidized asphalt feedstock. The mixture of the concentrate and oxidized asphalt is then heated to generate the shingle roofing coating. The shingle roofing coating includes between 10% by weight and 30% by weight of the concentrate and between 0.1% by weight and 6% by weight of the elastomeric polymer.

A method for generating a shingle roofing coating comprising:
- mixing an elastomeric polymer and an asphalt flux to generate a concentrate, wherein the concentrate includes 1% by weight to 20% by weight of the elastomeric polymer;
- heating the concentrate;
- mixing the concentrate with an oxidized asphalt feedstock;
- and
- heating the mixture of the concentrate and the oxidized asphalt feedstock to generate the shingle roofing coating, wherein the shingle roofing coating includes between 10% by weight and 30% by weight of the concentrate, and wherein the shingle roof coating includes between 0.1% by weight and 6% by weight of the elastomeric polymer.
A shingle roofing coating composition comprising:
- an oxidized asphalt feedstock;
- and
- a concentrate including an elastomeric polymer and an asphalt flux, wherein the concentrate includes 1% by weight to 20% by weight of the elastomeric polymer;
- wherein the shingle roofing coating composition includes between 10% by weight and 30% by weight of the concentrate, and wherein the shingle roofing coating composition includes between 0.1% by weight and 6% by weight of the elastomeric polymer.
