ROOFING SHINGLE
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 (1/8 inch) to 50.8 mm (2 inches). In addition, the fibrous substrate has (i) a basis weight of 39.05 g/m2 (0.8 lb/100 ft2) to 134.3 g/m2 (2.75 lb/100 ft2) 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.
