A shingle includes a substrate having an asphalt coating on a top surface of the substrate and on a bottom surface of the substrate. A surface layer of granules is embedded in the asphalt on the top surface of the substrate. A backdust layer of particles is embedded in the asphalt on the bottom surface of the substrate. A sealant is disposed on the backdust. A hydrophobic material is applied to the sealant.
