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.

A shingle including a fibrous substrate that reduces or prevents asphalt bleed through is provided. The fibrous substrate has a top surface and a bottom surface opposed to the top surface. Asphalt coating is applied to the top surface of the fibrous substrate. The fibrous substrate includes fibers having a diameter of 3.5 microns to 30 microns and a length of 3.175 mm ( inch) to 50.8 mm (2 inches). In addition, the fibrous substrate has (i) a basis weight of 39.05 g/m.sup.2 (0.8 lb/100 ft.sup.2) to 134.3 g/m.sup.2 (2.75 lb/100 ft.sup.2) and/or (ii) a thickness of 0.381 mm (15 mils) to 1.143 mm (45 mils). A ratio of the amount of asphalt coating on the bottom surface to the amount of asphalt coating on the top surface is from 0:1 to 1:5.

A method of forming a roofing-grade asphalt mixture can include mixing a bio-asphalt including a partially oxidized bio-source material, a bitumen source material different from the bio-asphalt, and particles to form the roofing-grade asphalt mixture. In an embodiment, the bitumen source material can have a softening point of at least approximately 102 C. and a penetration distance no greater than approximately 20 dmm. In another embodiment, the roofing-grade asphalt mixture can have a softening point of at least approximately 104 C., a penetration distance no greater than approximately 12 dmm, a viscosity of at least approximately 3000 cps at a temperature of 177 C., or any combination thereof. The roofing-grade asphalt mixture can be applied to a base material to form a roofing product.
