Abstract
An asphalt-based roofing material includes a substrate coated with an asphalt coating, a protective coating adhered to the upper surface of the asphalt coating, a layer of granules adhered to the protective coating, and a web bonded to the lower region of the asphalt coating. A method of manufacturing a roofing material includes coating a substrate with an asphalt coating, applying a protective coating to the upper surface of the asphalt coating, applying a layer of granules to the protective coating, and applying a web to the lower region of the asphalt coating.
Claims21
An asphalt-based roofing material comprising:
- a substrate coated with an asphalt coating, the asphalt coating including an upper surface that is positioned above the substrate when the roofing material is installed on a root, and a lower region that is positioned below the substrate when the roofing material is installed on the roof,
- a protective coating adhered to the upper surface of the asphalt coating,
- a surface layer of granules adhered to the protective coating, and
- a web bonded to the lower region of the asphalt coating, the web comprising materials having an ultimate tensile elongation of greater than about six percent.
An asphalt-based roofing material including a portion that is normally exposed when the roofing material is installed on a roof, the roofing material comprising:
- a substrate coated with an asphalt coating, the asphalt coating including an upper surface that is positioned above the substrate when the roofing material is installed on the roof,
- a protective coating adhered to the upper surface of the asphalt coating, the protective coating comprising a unitary layer covering at least about 80% of the upper surface of the asphalt coating in the exposed portion of the roofing material, and a surface layer of granules adhered to the protective coating.
An asphalt-based rooting material comprising:
- a substrate coated with an asphalt coating, the asphalt coating including an upper surface that is positioned above the substrate when the roofing material is installed on a roof,
- a protective unitary coating adhered to the upper surface of the asphalt coating, and
- a surface layer of granules adhered to the protective coating, wherein at least a portion of the granules penetrate the asphalt coating, and wherein the protective coating provides a seal to prevent outside moisture from flowing around the granules to the asphalt coating.
