Asphalt-based roofing materials, such as shingles, are disclosed that include a layer of parting material. The layer of parting material is applied to at least a part of the top, bottom, or both the top and the bottom of the shingle. When the shingle includes the parting material on the bottom, the layer of parting material replaces all or a portion of a backdust layer. When the shingle includes the layer of parting material on the top, the layer of parting material replaces a portion of granules on the shingle. The layer of parting material can be applied to the shingle in patterns and configurations that permit an adhesive to be applied to the shingle and function as intended. The parting material may include a metal salt of a fatty acid, a polyolefin, and/or a crosslinkable silane.

Roofing materials including a parting agent layer

A shingle including a substrate having a first surface defining an upper side of the shingle and an opposing 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; a plurality of granules embedded in the first asphalt coating; a first hydrophobic material; and a second hydrophobic material that is a different composition than the first hydrophobic material and the second hydrophobic material comprises a metal stearate, wherein the lower side of the shingle includes a lower surface and the first and the second hydrophobic material are disposed on the lower surface.

Shingles with increased hydrophobicity

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.
