Abstract
A shingle includes a substrate, a surface layer of granules, a backdust layer, an adhesive, and a hydrophobic material. Asphalt is applied to the substrate to form a first asphalt coating on the top or upper surface of the substrate and a second asphalt coating on the bottom or lower surface of the substrate. A surface layer of granules is embedded in the first asphalt coating. A backdust layer of particles is embedded in the second asphalt coating. A adhesive is disposed on the backdust layer. The hydrophobic material is applied to the adhesive.
