A roofing product includes coating a substrate with bitumen to yield a bitumen coated substrate having an exposure zone. First granules are adhered to the exposure zone to yield a first granule coating. The first granules have a solar reflectance greater than 35. An adhesive is adhered to at least a portion of the first granule coating. An open portion of the first granule coating that is free of the adhesive is maintained. An overlay of non-white second granules is adhered to the adhesive, such that the overlay of second granules and the adhesive provide a raised structure above a plane of the first granule coating.

System, method and apparatus for increasing average reflectance of a roofing product for sloped roof

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 roofing product and method includes coating a substrate with bitumen to yield a bitumen coated substrate having an exposure zone. First granules are adhered to the exposure zone to yield a first granule coating. The first granules have a solar reflectance greater than 35. An adhesive is adhered to at least a portion of the first granule coating. An open portion of the first granule coating that is free of the adhesive is maintained. An overlay of non-white second granules is adhered to the adhesive, such that the overlay of second granules and the adhesive provide a raised structure above a plane of the first granule coating.

A simultaneously molded plurality of composite shingles or double walled shingles or other substantially planar exterior building products are provided, each being comprised of two or more layers of thermoplastic shingle material, such that a weatherable capstock material is provided outside a core material, in the form of a composite parison that is then blow molded in a hollow mold, to produce novel shingles. Ventilation and/or insulation can be provided to a hollow interior between spaced apart walls of a double walled shingle.

Composite building product

A process of simultaneously molding either a plurality of composite shingles or double walled shingles or other substantially planar exterior building products is provided, each being comprised of two or more layers of thermoplastic shingle material, such that a weatherable capstock material is provided outside a core material, in the form of a composite parison that is then blow molded in a hollow mold, to produce novel shingles according to the process. Ventilation and/or insulation can be provided to a hollow interior between spaced apart walls of a double walled shingle.
