A roofing shingle comprising a base mat having a tab portion covered with granules and a headlap portion covered with a mask or film layer. An asphalt-based coating is applied to at least a top surface of the base mat. The film layer is adhered to the asphalt-based coating applied to the headlap portion and the granules are adhered to the asphalt-based coating applied to the tab portion. The film layer is adapted for preventing granules from adhering to the headlap portion of the base mat and, as such, the headlap portion may be substantially free from any granules adhered thereto. A method for manufacturing a roofing shingle is also provided wherein granules that are not adhered to the tab portion of one shingle may be collected and reapplied the tab portion of another shingle.

Shingle with headlap mask

In one embodiment, a shingle includes a first layer having at least one full tab and at least one full cut-out. A second layer is positioned under the first layer. The full tab width to first layer length ratio is greater than 8.5/36. The full cut-out width to first layer length ratio is greater than 8.5/36. A method that includes applying such shingles to a roof.

Shingles and methods of applying shingles

A method for making laminated roofing shingles includes providing a substantially continuous sheet of shingle material, cutting the sheet material at a first cutting station to define a first pair of longitudinal strips having interdigitating tabs with a first pattern length, further cutting the sheet to define a second pair of longitudinal strips, further cutting the sheet at a second cutting station to define a third pair of strips having interdigitating tabs with a second pattern length, laminating together one of the first pair of strips, one of the second pair of strips and one of the third pair of strips in overlapping relation to form a substantially continuous three-layer laminated strip in which one of the second pair of strips is the lowermost layer and having the tabs of the remaining two strips oriented in a common lateral direction, and cutting the laminated strip into uniform longitudinal lengths whereby laminated roofing shingles are made.

Method for making laminated roofing shingles

A method and apparatus for producing a self-adhering product with a multi-part release liner system that will not result in unwanted adhesion at the edges is disclosed. The self-adhering product may be a roofing sheet, or waterproofing membrane. The multi-part release liner system includes a strip of material placed on the adhesive surface below and between each abutting edge of the release liner. The material allows each section of the release liner to be removed without the edges of the liner adhering to the underlying sheet. The release liner may also be a single piece liner, with at least one strip of perforations that allows the liner to be removed in individual sections. In this application, the material not only prevents edge adhesion, but also prevents adhesive from the substrate flowing through the perforation holes. The invention may also be applied to release liner systems that combine multi-part release liners and perforated release liners. The method and apparatus of the invention are applicable to any self-adhesive product that requires a release liner.

The length of the shingles is not an integer multiple of either the first or second pattern lengths.
