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.

Claims5

Dependent claims

A roofing shingle comprising:

a substrate;
an asphalt coating composition on the substrate;
and
a nail zone reinforcement material disposed on the asphalt coating composition, the nail zone reinforcement material comprising a polyester fabric, wherein a surface of the polyester fabric is modified by NaOH treatment,
wherein NaOH treatment of the polyester fabric creates an increase in carboxylic acid groups that increase adhesion between the nail zone reinforcement material and the asphalt coating composition compared to a polyester fabric that has not been modified by NaOH treatment disposed on an identical asphalt coating composition.
