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.

Polymer modified asphalt roofing material

An exemplary shingle includes at least one coated shingle sheet defining a headlap portion and a tab portion each having opposed upper and lower surfaces. A first line of adhesive is adhered to one of the upper surface of the headlap portion and the lower surface of the tab portion, and includes a first thermally activated adhesive material. A second line of adhesive is adhered to one of the upper surface of the headlap portion and the lower surface of the tab portion, and includes a second thermally activated adhesive material having a minimum activation temperature less than a minimum activation temperature of the first thermally activated adhesive material.
