Shingles with increased hydrophobicity

A bundle of shingles comprising:

• a first shingle stacked upon a second shingle, where the first and second shingle each comprises:
• a substrate having a first surface defining an upper side of the shingle and an opposed a second surface defining a lower side of the shingle;
• asphalt infiltrating the substrate to form a first asphalt coating on the first surface of the substrate and a second asphalt coating on the second surface of the substrate;
• an adhesive on the lower side of the shingle;
• a plurality of granules embedded in the first asphalt coating, forming a surface layer on the shingle;
• a first hydrophobic material coated on the surface layer;
• and
• a second hydrophobic material applied to the adhesive,
• wherein the first and second shingle are stacked such that the first surface of the first shingle is proximal to and in contact with the first surface of the second shingle, and each of the shingles in the bundle of shingles has a lap shear strength of less than 50 lbs of force.

• a first hydrophobic material coated on the backdust layer;
• and
• a second hydrophobic material applied to the adhesive,
• wherein the first and second shingle are stacked such that the second surface of the first shingle is proximal to and in contact with the second surface of the second shingle, and wherein said bundle of shingles demonstrate a lap shear strength of less than 50 lbs of force.
