Claims20
A roofing shingle having an upper edge, a lower edge, a first end, and a second end, the roofing shingle comprising:
- a headlap section extending from the upper edge of the shingle toward the lower edge;
- an exposure section below the headlap section and extending from a lower edge of the headlap section to the lower edge of the shingle;
- and
- a nailing zone extending across the roofing shingle from the first end to the second end within the headlap section,
- the roofing shingle being formed of
- an overlay sheet having a top surface and a bottom surface;
- and
- an underlay sheet having a top surface and a bottom surface,
- each of the overlay sheet and the underlay sheet comprising
- a substrate,
- a top asphalt layer extending from a top surface of the substrate and being surfaced with one or more top surfacings, and
- a bottom asphalt layer extending from a bottom surface of the substrate and being surfaced with one or more bottom surfacings,
- the overlay sheet overlapping the underlay sheet along an overlap zone extending from the first end to the second end of the roofing shingle in or adjacent the nailing zone, with the top surface of the underlay sheet being affixed to the bottom surface of the overlay sheet in the overlap zone,
- the top surfacings of any exposed area of the overlayp sheet and the underlay sheet in the exposure zone being roofing granules;
- wherein
- (a) a bottom portion of each of the overlay sheet and the underlay sheet comprising the bottom asphalt layer and the one or more bottom surfacings has a weight of no more than 11 pounds per 100 square feet, or
- (b) the roofing shingle has at its top surface a small particulate zone defined by a top surfacing of a small particulate material extending from the first end to the second end of the roofing shingle, the small particulate material having a d50 particle size of no more than half a d50 particle size of roofing granules disposed as a top surfacing in a lower adjacent zone to the small particulate zone, the small particulate zone being at least one inch in height as measured in a direction from the upper edge to the lower edge of the shingle, the small particulate zone at least partially overlapping the overlap zone.

A palleted plurality of roofing shingles comprising a plurality of roofing shingles disposed in one or more stacks on a pallet, wherein the pallet has a top surface formed of a plurality of top boards, and wherein
- (a) adjacent boards of the plurality of top boards have a gap of no more than one inch therebetween at the top surfaces thereof;
- and/or
- (b) the plurality of top boards take up at least 85% of the occluded area of the top surface of the pallet;
- (c) each of the plurality of top boards has a thickness of at least 0.55 inches, and
- wherein each roofing shingle has an upper edge, a lower edge, a first end, and a second end, each roofing shingle comprising:
- a headlap section extending from the upper edge of the shingle toward the lower edge;
- an exposure section below the headlap section and extending from a lower edge of the headlap section to the lower edge of the shingle;
- and
- a nailing zone extending across the roofing shingle from the first end to the second end within the headlap section,
- the roofing shingle being formed of
- an overlay sheet having a top surface and a bottom surface;
- and
- an underlay sheet having a top surface and a bottom surface,
- each of the overlay sheet and the underlay sheet comprising
- a substrate,
- a top asphalt layer extending from a top surface of the substrate and being surfaced with one or more top surfacings, and
- a bottom asphalt layer extending from a bottom surface of the substrate and being surfaced with one or more bottom surfacings,
- the overlay sheet overlapping the underlay sheet along an overlap zone extending from the first end to the second end of the roofing shingle in or adjacent the nailing zone, with the top surface of the underlay sheet being affixed to the bottom surface of the overlay sheet in the overlap zone,
- the top surfacings of any exposed area of the overlayp sheet and the underlay sheet in the exposure zone being roofing granules,
- wherein
- (a) the bottom portion of each of the overlay sheet and the underlay sheet comprising the bottom asphalt layer and the one or more bottom surfacings has a weight of no more than 11 pounds per 100 square feet, and/or
- (b) the shingle has at its top surface a small particulate zone defined by a top surfacing of a small particulate material extending from the first end to the second end of the roofing shingle, the small particulate material having a d50 particle size of no more than half a d50 particle size of roofing granules disposed as a top surfacing in a lower adjacent zone to the small particulate zone, the small particulate zone being at least one inch in height as measured in a direction from the upper edge to the lower edge of the shingle, the small particulate zone at least partially overlapping the overlap zone.
