  • Roofing shingles with reduced usage of conventional shingle material having side lap extension
    Patent number: 8925272
    Abstract: 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.

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.
