摘要:
The present disclosure relates, in some embodiments, to systems, articles, materials, and methods for roofing a structure including, for example, hybrid shingles comprising a first material and a second material. A hybrid shingle may comprise, in some embodiments, a first layer comprising a metallic substrate or a polymeric substrate and at least partially defining a headlap region of the shingle, a buttlap region of the shingle comprising one or more tabs interspersed with inter-tab openings, an outward-facing surface of the first layer, and a substrate-facing surface of the first layer; and a second layer comprising a base and asphalt, having a smaller area than the first layer, and at least partially defining a buttlap region of the shingle, wherein the second layer is fixed to the substrate-facing surface of the first layer.

A laminated roofing shingle is provided, having an anterior shingle layer and a posterior shingle layer. Openings exist in tab portions of the anterior shingle layer, allowing for visible front surface portions of the posterior shingle layer to be visible through the openings. Such visible portions can be of varying vertical contrast from at least some of the top edges of the openings to at least some of the bottom edges of the posterior shingle layer that are exposed through the openings, and are generally of consistent horizontal contrast between right and left edges of the openings. Front surface portions of the posterior shingle layer that are exposed through one or more openings have a different contrast that is in interrupting contrast to at least a portion of any of the varying or consistent contrast that are visible through the openings between tabs of the anterior shingle layer.

According to one embodiment, a method for pressing roofing granules into a roofing membrane may include providing a roofing membrane and applying roofing granules atop a surface of the membrane. The method may also include adjusting a position of a second roller relative to a first roller so as to vary an amount of contact between the membrane and the first roller and pressing the roofing granules into the membrane via the first roller. In some embodiments, a line speed of the membrane may be determined and a contact value may be calculated based on the line speed of the membrane. The contact value may represent an effective amount of contact between the membrane and the first roller. The position of the second roller may be adjusted so that the amount of contact between the membrane and the first roller corresponds to the effective amount of contact.

A roofing shingle is provided. The roofing shingles includes an overlay sheet including a headlap portion and a tab portion and an underlay sheet secured to the overlay sheet such that a region of the underlay sheet overlaps a region of the headlap portion of the overlay sheet. A reinforcement material is secured to the headlap portion of the overlay sheet. The reinforcement material is configured to improve nail pull-through. The reinforcement material extends beyond the overlapping regions of the headlap portion and the underlay sheet a distance of about 0.12 inches or less.

A roofing granule can include a base particle having a base material and a layer covering the base particle of the roofing granule. The layer can has a first material and a second material that includes a metal carbonate, wherein the first and second materials include a same metal element, and the base material is different from the first material. In a process of forming the roofing granule, the layer can have pores. The process can include infiltrating a fluid into the pores of the layer while the base particle is present and adjacent to the layer, wherein the fluid includes a carbonate. The process can further include reacting the carbonate with a metal compound within the layer to form a metal carbonate within the layer. The roofing granules can be used in roofing products.

Algae-resistant roofing shingles are formed by extruding a mixture of mineral particles and a binder to form porous granule bodies, and algaecide is distributed in the pores to provide alqae-resistant granules, which are subsequently applied to roofing shingles. Release of the algaecide is controlled by the structure of the granules.

A high speed granule delivery system and method is disclosed for dispensing granules in intermittent patterns onto a moving asphalt coated strip in the manufacture of roofing shingles. The system includes a granule hopper and a rotationally indexable pocket wheel in the bottom of the hopper. A series of pockets are formed in the circumference of the wheel and the pockets are separated by raised lands. A seal on the bottom of the hopper seals against the raised lands as the wheel is indexed. In use, the pockets of the pocket wheel drive through and are filled with granules in the bottom of the hopper. As each pocket is indexed beyond the seal, it is exposed to the moving asphalt coated strip below and its granules fall onto the strip to be embedded in the hot tacky asphalt. Well defined patterns of granules are possible at high production rates.

A method of manufacturing a granule coated asphaltic article comprising the steps of applying liquid asphalt to a reinforcing sheet to create an asphaltic sheet, the asphaltic sheet having a top surface and a bottom surface; bending the asphaltic sheet to form an arcuate top surface of the sheet; and applying a coating of granules over the arcuate top surface of the asphaltic sheet.
摘要:
A shingle, a method of making it, and a roof embodying the shingle is provided, in which an exterior surface of the shingle is provided with an attached reinforcement layer through which fasteners may be applied when the shingle is applied to a roof.
摘要:
A method of manufacturing a granule coated asphaltic article is disclosed. The method includes applying molten asphalt to a reinforcement to create an asphaltic sheet, the asphaltic sheet having a top surface and a bottom surface. Next, the asphaltic sheet is bent to form an arcuated top surface of the sheet. The method concludes by applying a plurality of granules to the arcuated top surface of the asphaltic sheet.
