Abstract: A panel for polypropylene injection molded siding, and for similar materials and/or uses, is mounted in lapped courses with panels attached at butt joints in a direction of elongation. Complementary tabs and slots at the panel ends can be engaged by end-to-end approach of the abutting panels. Additionally, openings for the tabs permit engagement from a position in which the panel ends are already overlapped, which reduces or eliminates the need for endwise assembly space. The slots can be discontinuous on one or both sides, openings permitting lateral insertion of the tabs at gaps, whereupon movement of the tabs along the slots engages the joint. The panels can simulate wood siding and include a step between simulated courses. A gap is provided in the edge of the panel at the step, thus forming an opening for the tab to enter and move along the slot.

Abstract: Panels which are joined at their opposing end faces are used to create a panel assembly. The opposing end faces may be a tongue and groove arrangement or they may consist of matching beveled recesses. In either case, the interrelationship between the opposing end faces is such that, upon assembly, an intervening space is created between adjoining panels. This intervening space eliminates the cantilever force effect associated with known panel assemblies and it results, instead, in a shear force which is evenly distributed over the full extent of the abutting panel faces.

Abstract: An improved waterproofing system for the concrete slab of a flat roof on a building is disclosed. The waterproofing system uses hollow plastic panels of designed size, different thickness, and groove and tongue joints for interconnecting the panels. A supplementary waterproofing layer may be installed using sheet membrane materials such as asphalt sheet, metal sheet and other sheets on vertical surfaces, especially the parapet of the roof. The invention further concerns a construction method for applying a fiber mesh reinforcement on the connection joint and for applying fluid-applied materials on the substrate with sheet membrane layers on vertical surfaces. The waterproofing layer of sloped step type, hollow plastic panels of different thickness, permits fast drainage of stagnant water, which inhibits weather damage to the waterproofing layer.

Abstract: The roof shingle system of the present invention includes rows of shingle elements having parallel, slanting lower edges that are aligned to divert the flow of water away from areas where high flow volumes are not desired toward areas where high flow volumes will not cause harm. Because water flowing down a surface will tend to adhere to that surface, the water flowing down the surface of the shingle system of the present invention will tend to follow the slanting lower edges of the shingle elements in the direction of the slanted edges so as to provide a way to control the flow of water on the surface of a roof.

Abstract: An integral, one-piece, multi-layered shingle and method of fabrication from a planar sheet of shingle material, e.g., asphalt. The planar sheet comprises a base portion having first and second, parallel, lateral edges, with plural elongated tabs extending from the first lateral edge. The plural elongated tabs are uniquely different but each features a side edge midportion perpendicular to the first lateral edge. Extending from the second lateral edge are a like plurality of short tabs, where the short tabs are laterally offset from the elongated tabs. In a roof placement mode, the elongated tabs are first folded onto the base portion at a midpoint thereof, then reversely bent back upon themselves to form a three layer section. To complete the fabrication, the base portion is folded toward the folded elongated tabs such that the short tabs are positioned adjacent at least one elongated tab to form a second section of two layers.

The shingles may be used in a ventilated roofing system, which includes a surfacing structure coupled to a roofing substrate. The surfacing structure is elevated with respect to the substrate such that an airspace is disposed between the substrate and the underside of the surfacing structure.

Abstract: Self-aligning shingle members and self-aligning laminated shingle members. The shingle members have at least an alignment strip on the bottom surfaces which mates and nests with the top edge or corresponding alignment strip on the underlying course of shingles. In one embodiment, each of the shingle members has an alignment strip on the bottom surface which nests with the top edge of the underlying course, creating a self-aligning roofing shingle system which is easier to align and install. In another embodiment, alignment strips are provided on both the top and bottom surfaces of the shingle member and the alignment strip on the bottom surface is adopted to mate and nest with the alignment strip on the top surface of shingle members in the underlying course of shingles. This provides a self-aligning shingle system with the appearance of a three-layer laminated shingle structure. The courses of shingle members can also be interlocked together with appropriately shaped interlocking alignment strips.

Abstract: Roofing tiles have dimensions differing from conventional tiles to allow manufacture of the tiles in a substantially greater size than conventional tile sizes. The tiles may be installed more rapidly, since each piece of material must be separately installed and a single tile may cover a greater area. Additional ribs are added underneath the interior portion of each tile than with conventional tiles. The ribs are spaced appropriately such that a person walking over each tile would have the weight of a single foot distributed over one or more ribs at all times. Moreover, the rims of each tile extend substantially deeper, through the thickness, of the tile. Each tile has material removed from the main surface portion, or the actual surface opposite the weather-exposed surface, to reduce the weight therefrom. Each tile may be configured with open air channels underneath each tile up and down the entire roof.
