Abstract
An asphalt-based roofing material includes a substrate coated with an asphalt coating. The asphalt coating includes a lower region that is positioned below the substrate when the roofing material is installed on a roof. A web is fused to the lower region of the asphalt coating. A portion of the web and of the asphalt coating have been intermingled by melting, thereby fusing the web and the asphalt coating. A method of manufacturing the asphalt-based roofing material includes the steps of coating a substrate with an asphalt coating, applying a web to the lower region of the asphalt coating, and intermingling a portion of the web and of the asphalt coating by melting, thereby fusing the web to the lower region of the asphalt coating.
Claims32
An asphalt-based roofing material comprising:
- a substrate coated with an asphalt coating, the asphalt coating including a lower region that is positioned below the substrate when the roofing material is installed on a roof, and
- a web fused to the lower region of the asphalt coating, wherein a portion of the web and of the asphalt coating have been intermingled by melting, thereby fusing the web and the asphalt coating.
An asphalt-based roofing material comprising:
- a substrate coated with an asphalt coating, the asphalt coating including a lower region that is positioned below the substrate when the roofing material is installed on a roof, the lower region including a lower surface, and
- a web fused to the lower surface of the asphalt coating, wherein a portion of the web and of the asphalt coating have been intermingled by melting, thereby fusing the web and the asphalt coating.
A method of manufacturing an asphalt-based roofing material, comprising the steps of:
- coating a substrate with an asphalt coating, the asphalt coating including a lower region that is positioned below the substrate when the roofing material is installed on a roof,
- applying a web to the lower region of the asphalt coating, and
- intermingling a portion of the web and of the asphalt coating by melting, thereby fusing the web to the lower region of the asphalt coating.
A method of manufacturing an asphalt-based roofing material, comprising the steps of:
- applying a web to a substrate,
- coating the substrate and the web with an asphalt coating, the asphalt coating including a lower region that is positioned below the substrate when the roofing material is installed on a roof, wherein the web is in contact with the lower region of the asphalt coating, and
- intermingling a portion of the web and of the asphalt coating by melting, thereby fusing the web to the lower region of the asphalt coating.
