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.

Shingle sealing arrangements

An exemplary roofing system for covering an existing shingle roof with an exposure height measured between bottom edges of adjacent courses is disclosed. The roofing shingle system comprising includes a plurality of reroofing shingles. The reroofing shingles have an exposure portion extending from a top edge to a bottom edge for a height that is at least the exposure height of the existing shingle roof. At least one course of reroofing shingles is installed on at least one course of the existing shingle roof, wherein the course of the existing roof is covered by the at least one course of reroofing shingles. The top edge of the reroofing shingles abuts the bottom edge of the adjacent course of existing shingles.
