A roofing shingle includes a shingle body having a buttlap portion with a butt edge and a headlap portion with a head edge. The shingle body also has a first side edge, a second side edge, and an exposure zone extending from the butt edge toward the headlap portion that is configured to be exposed to the environment when the shingle is installed on a roof. A water impermeable sheet is attached to the shingle body. The sheet has a width, length, first end and second end. The width extends from approximately the head edge to approximately the butt edge of the shingle body. The length extends from the first end to the second end. At least a portion of the length extends beyond the first side edge of the shingle body by at least about 2 inches. The sheet is formed from a different material than the shingle body.

Roofing shingles with reduced usage of conventional shingle material having side lap extension

A roofing shingle includes a shingle body having a buttlap portion with a butt edge and a headlap portion with a head edge, a first side edge and a second side edge. An exposure zone extends from the butt edge toward the headlap portion and is configured to be exposed to the environment when the shingle is installed on a roof. A water impermeable sheet is attached to the shingle body and has a width, length, first end and second end. The width extends from between about the butt and head edges to beyond the head edge of the shingle body. The length extends from between about the first and second side edges to beyond the first side edge. The sheet is formed from a different material than the shingle body.

Roofing shingles with reduced usage of conventional shingle material and having a combination vertical and lateral lap extension

A roofing shingle has a shingle body with a butt edge, a headlap portion, a head edge, and first and second side edges. An exposure zone has a width that extends from the butt edge toward the headlap portion and is configured to be exposed to the environment when the shingle is installed on a roof. A water impermeable sheet is attached to the shingle body. The sheet has a width with upper and lower edges. The width extends from between about the butt and head edges to beyond the head edge of the shingle body. The width of the shingle body is such that a first distance between the head edge of the shingle body and the upper edge of the water impermeable sheet is equal to or greater than the width of the exposure zone. The sheet is formed from a different material than the shingle body.

Roofing shingles with reduced usage of conventional shingle material and having top lap extension

A package is provided, of specialty roofing materials, including a plurality of stacked shingles in the package, in nested relation, with the shingles being of variable thickness from one end to the other in one or more stacks, as packaged, to be of 'V' configuration, and of various selected orientations, and forming a substantially hollow zone, with at least one insert structure to fill the hollow zone and provide support for the end shingle in the stack. The at least one insert structure may be constructed of various materials, such as folded cardboard, cellular foam or the like. Filler material may be provided in the package, for any voids between the stack of shingles and the upper end of the package.
