Disclosed is an apparatus for venting buildings, specifically attic spaces, such vents being predominantly shape-conform to the components from which a wall or a roof is built (typically tiles, in the context of roofs), the vent typically being fabricated from a metallic, plastic, or ceramic core as well as one or more layers from other materials or compounds which modify the overall characteristics of the vent, such as the surface characteristics. Furthermore disclosed are methods of manufacturing such ventilation apparatuses.

A process for in-line extrusion of polymeric coatings onto roofing shingles during manufacturing includes moving a web of shingle substrate material in a downstream direction and extruding a liquefied coating of polymeric material onto at least one surface of the moving web to form a thin film. The liquefied coating may be a molten polymeric material that forms a thin film on a back surface of the shingle material to prevent sticking and eliminate the need for a traditional back dusting with material such as powdered stone. The polymeric film further may be applied to the substrate material in lieu of a saturation coating of asphalt, thus reducing cost and weight while providing a comparable moisture barrier and a lighter more flexible shingle.

A bio-composite construction material for use as a substrate for a tile, a shingle, or a building panel. The bio-composite construction material may be formed into a rigid or semi-flexible member. A hemp fiber component is mixed with a binding agent to create the bio-composite construction material. The rigid member utilizes hemp hurd fibers mixed with lime or clay and water to form a tile structure. The semi-flexible member utilizes hemp primary bast fibers to form an elongated structure that is flexible. Hemp lignin or a resin is used as the binding agent and the primary bast fibers may be woven or alternately layered to create a substrate for a roof shingle.

Roofing shingles are disclosed that are capable of being attached to a roof deck, underlayment, and/or other roofing shingles and that require few mechanical fasteners to remain attached to the roof. The roofing shingles are formed with a first layer and a second layer of shingle materials that are laminated together, and with the first and second layers further being mechanically attached with indentations in the first and second layers at spaced locations along and across the roofing shingles. A roofing system comprising a plurality of courses of the roofing shingles is also disclosed.

A roofing shingle includes an overlay sheet, an underlay sheet, and a reinforcement member. The overlay sheet includes a headlap portion and a tab portion, wherein the overlay sheet has an overlay sheet height. The underlay sheet is secured to a bottom surface of the overlay sheet such that a region of the underlay sheet overlaps a region of the headlap portion of the overlay sheet. The reinforcement material is secured to a top surface of the headlap portion of the overlay sheet, wherein the reinforcement material is configured to improve nail pull-through, wherein the reinforcement material extends beyond the overlapping regions of the headlap portion and the underlay sheet.

A roofing shingle includes a head lap and at least one solar cell. The head lap includes at least one handle located between a first end and a second end of the shingle and proximate to a first edge thereof. The at least one handle includes at least one cutout and a gripping portion. The at least one cutout is sized and shaped to receive an external object to facilitate transporting the shingle by a user.
