Abstract: A mesh ridge vent has an air permeable layer formed of randomly aligned synthetic fibers that are opened and blended, randomly aligned into a web by airflow, joined by phenolic or latex binding agents, and heat cured to produce an air-permeable varying mesh. A moisture barrier may be integrally formed above the air permeable layer and may be defined by a coating or by a layer of fibers that is sufficiently dense to inhibit penetration of water into the web. The mesh ridge vent has edge portions and a central portion and the edge portions may be more dense and thicker while the central portion may be less dense and thinner than the edge portions.

Abstract: An asphalt-based shingle is formed with a substrate saturated with asphalt, an asphalt coating on the saturated substrate, and a top film bonded to the surface of the asphalt coating covering at least a portion of the shingle to be exposed when installed, The top film may be configured to mimic the appearance of traditional clay granules on the shingle or another shingle surface. More specifically, the top film is printed or coated with an image that mimics the appearance of a clay granule bed and is embossed, pressed, or molded to mimic the texture of a clay granule bed. The top film is UV resistant to protect the asphalt below from deterioration. An anti-stick film may be bonded to the back of the shingle to prevent shingles from sticking together when stacked into a bundle.

Abstract: A roofing system and roofing shingles for use therein are disclosed. The roofing system comprises a multiplicity of courses of roofing shingles having a headlap portion, a buttlap portion, a lateral leading edge, and a lateral trailing edge, wherein the headlap portion has a width that is less than a width of the buttlap portion defining a reduced-width headlap, wherein the lateral trailing edge of a shingle in a course partially overlaps and partially abuts the lateral leading edge of an adjacent previously installed shingle to form an interlocking edge between adjacent shingles in the course, and wherein the lateral edge includes a trailing edge projection having a weather edge, a rear edge, and a variable breadth that increases toward the rear edge of the trailing edge projection.

Abstract: A roofing panel has a field, an upper edge, a lower edge, a first end, and a second end. The field of the roofing panel is ornamented such as by being coated and/or embossed and/or pressed to emulate the appearance of a traditional roofing shingle. A clip extends along the forward edge of the roofing panel and projects downwardly therefrom. A slot extends along the rear edge of the roofing panel and the slot has an upwardly facing elongated opening. The slot is cut short or truncated at the first end of the roofing panel such that the second end of a like shingle can be overlapped onto the first end in such a way that the ornamentation on the field of the roofing panel prevents water migration through the region of overlap of the roofing panel and the like roofing panel. The clip is configured to be pressed down by an installer through the opening of the slot and lock within the slot to attach one course of shingles securely to a next lower course of shingles.

Abstract: A finished flake for a roofing material including a metal flake substrate having an emissivity value up to approximately 0.25 and a reflectivity value up to approximately 0.95. A first coating is provided having unpigmented sodium silicate disposed on the substrate, wherein the first coating increases the emissivity value of the substrate and decreases the reflectivity value of the substrate. A second coating is provided having sodium silicate loaded with reflective pigments non-uniformly disposed about the first coating, wherein the finished flake has an emissivity value in excess of approximately 0.75 and a reflectivity value ranging from approximately 0.4 to approximately 0.5.

Abstract: Metal roofing panels have a forward edge portion with a downwardly extending skirt and return flange and a rear edge or headlap portion with an upwardly open channel and a locking tab extending over a portion of the upwardly open channel. A method of installing the roofing panels includes nailing a lower course of panels in end-to-end overlapping relationship to a roof deck. The forward edge portions of panels in the next higher course of panels are then pressed downwardly into the upwardly open channels of the lower course panels. The return flanges of the upper course panels snap beneath the locking tabs of the upwardly open channels thus locking the panels together and forming a watertight connection between courses of panels.

Abstract: An outside corner patch for TPO roofing is formed from a circular piece of TPO membrane material being vacuum formed to define an array of flutes that extend from the center of the piece toward its edges. The flutes form ridges and valleys that generally are shaped as conical sections with the apex of the conical sections located at the center of the patch. The number and size of the flutes is optimized in such a way that, when the flutes are stretched flat, the patch conforms to and fits flat against the surfaces of an outside corner formed by the intersection of a roof deck with an upward protrusion from the roof. The TPO outside corner patch is applied over the corner and thermally welded to surrounding TPO membranes on the roof deck and the protrusion to form a watertight seal at the outside corner.
