## Abstract

A shingle coating asphalt composition is provided that is produced from a paving grade asphalt. The asphalt composition comprises a paving-grade asphalt that has been modified with one or more polymer additives; and a secondary additive comprising one or more of a viscosity reducing agent, a wax, a salt of a fatty acid ester, and an amide of a fatty acid. The shingle coating asphalt coating composition is used to make a shingle. The shingle includes a substrate, the asphalt, and roofing granules.

## Claims

### Claim 1

A roofing shingle comprising:
a substrate;
a polymer and secondary additive modified asphalt coating on the substrate;
wherein the polymer and secondary additive modified asphalt coating comprises:
62 wt. % to 80 wt. % of a filler based on the total weight of the polymer and secondary additive modified asphalt coating;
an asphalt having a softening point of 60° F. to 130° F.;
