  • Shingle for optically simulating a tile roof
    Patent number: 6421976
    Abstract: A laminated shingle simulates a tiled roof when placed with other similar shingles on a roof deck. The laminated shingle includes an overlay member and an underlay member fixedly attached to each other. The overlay member includes an upper or headlap portion and a lower or exposed butt portion with one or more substantially identically shaped tabs with a cutout between each tab. The lower edge of the tabs may have a curving or negative contour. The tabs may taper in width from the butt edge to the lower edge of the headlap portion. The upper edge of the cutouts may have a generally straight contour or a generally curved contour. The lower edge of the underlay member may have a generally straight contour or a portion of the lower edge may have a generally curving contour. The overlay member and/or underlay member may include a darker shading area to enhance the tile simulating aspect of the shingle.

  • Vacuum treatment of asphalt coating
    Patent number: 6352744
    Abstract: In a method of reducing voids in an asphalt roofing product, an asphalt coating material having voids is contacted with a vacuum in an amount effective to reduce the voids in the coating material. A mat is coated with the coating material to make an asphalt roofing product. The vacuum contacting step occurs prior to the coating step. The vacuum contacting step causes the roofing product to have reduced voids visible on a top surface compared to the same roofing product made with a coating material not contacted with vacuum.
