Abstract

See full text

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.
