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. ## Claims ### Claim 1 A stack of shingles comprising: a first plurality of shingles stacked on a first pallet; a second pallet stacked on the first plurality of shingles;
