Patent Application
20190119916
The present invention relates generally to roof shingles for protecting a roof of a structure, and more particularly, hip and ridge shingles for application on hip or ridge portions of a roof.
Many structures have pitched, shingled roofs, which prevent water, e.g., rain water, from entering the structures by causing water to pass over the shingles and shed off the roofs. A pitched, shingled roof has a pitched substrate, such as a plurality of plywood sheets, with a plurality of shingles attached thereto.
Each shingle has an upper portion (i.e., a headlap portion) and a lower portion (i.e., an exposure portion) wherein the exposure portion is exposed to the environment. The shingles are typically attached to the substrate in rows known as courses wherein the exposure portion of an upper course of shingles overlaps the headlap portion of an adjacent lower course of shingles. For example, a first course of shingles may be attached to the substrate nearest the lowest point of the roof, i.e., the eave portion of the roof. A second course of shingles may then be attached to the substrate slightly higher on the roof than the first course. The shingles are placed so that the exposure portion of the second course of shingles overlaps the headlap portion of the first course of shingles. This overlapping continues with successive rows of shingles to the highest point on the area of the roof, i.e., the hip or the ridge.
Hip and ridge shingles applied along a hip or ridge of a roof (i.e., transverse to the courses of shingles). These hip and ridge shingles span a gap or intersection between courses of shingles of roof planes that meet at a hip or ridge. These hip and ridge shingles are typically applied along the hip or ridge in a similar fashion, with the exposure portion of one hip and ridge shingle covering the headlap portion of an adjacent shingle on the hip or ridge. Thus, only the exposure portion of the shingles are exposed to the environment. This overlapping of the shingles causes water to pass from shingles on higher courses to shingles on the next lowest course of shingles without contacting the substrate. Accordingly, water passes from shingle to shingle and off the roof without contacting the substrate or entering the structure.
Attaching the shingles to the roof is typically achieved by the use of nails or other fastening devices that pass through the shingles and into or through the substrate. The fastening devices are typically placed through the headlap portion of the shingles so that they are overlapped by shingles in an adjacent higher course as described above. This placement of the fasteners prevents water from entering the structure through holes caused by the fasteners.
Some roofs have a membrane (i.e., an underlayment) located between the substrate and the shingles. The membrane may, as an example, be conventional tar paper or other underlayment material that is nailed to the substrate. Strips of the membrane are typically attached to the roof in an overlapping fashion wherein an upper strip overlaps its adjacent lower strip. Accordingly, the membrane serves to shield the substrate from water should a shingle become damaged. For example, if a shingle becomes cracked or otherwise leaks, water will contact the membrane rather than the substrate. Water will then pass along the membrane without contacting the substrate or entering the structure.
Exemplary embodiments of shingles are disclosed herein.
An exemplary laminated shingle includes an overlay sheet having a top overlay surface, a bottom overlay surface, a headlap portion, and a tab portion arranged between two-cutouts. The shingle also includes an underlay sheet having a top underlay surface and a bottom underlay surface. The overlay sheet is attached to the underlay sheet such that a portion of the top underlay surface is exposed on a first side of the tab portion and a portion of the top underlay surface is exposed on a second side of the tab portion.
Another exemplary laminated shingle includes an overlay sheet having a top overlay surface, a bottom overlay surface, a headlap portion, and a cut-out arranged between two tab portions. The shingle also includes an underlay sheet having a top underlay surface and a bottom underlay surface. The overlay sheet is attached to the underlay sheet such that a portion of the top underlay surface is exposed between the first and second tab portions.
Still another exemplary laminated shingle includes an overlay sheet having a top overlay surface, a bottom overlay surface, a headlap portion, at least one tab portion, and at least one cut-out. The shingle also includes an underlay sheet having a top underlay surface and a bottom underlay surface. The overlay sheet is attached to the underlay sheet such that a portion of the top underlay surface is exposed adjacent the at least one tab portion.
These and other features and advantages of the present invention will become better understood with regard to the following description and accompanying drawings in which:
Prior to discussing the various embodiments, a review of the definitions of some exemplary terms used throughout the disclosure is appropriate. Both singular and plural forms of all terms fall within each meaning.
As described herein, when one or more components are described as being connected, joined, affixed, coupled, attached, or otherwise interconnected, such interconnection may be direct as between the components or may be indirect such as through the use of one or more intermediary components. Also as described herein, reference to a “member,” “component,” or “portion” shall not be limited to a single structural member, component, or element but can include an assembly of components, members or elements. Also as described herein, the terms “substantially” and “about” are defined as at least close to (and includes) a given value or state (preferably within 10% of, more preferably within 1% of, and most preferably within 0.1% of)

The overlay sheet 210 is attached to the underlay sheet 220 such that a portion of the top underlay surface is exposed on a first side of the tab portion 216 and a portion of the top underlay surface is exposed on a second side of the tab portion 216. The first and second cut-outs 222 can have the same or different widths. In some embodiments, the widths of the first and second cut-outs 222 range from about 5 percent to about 30 percent, or about 10 percent to about 25 percent, or about 15 percent to about 20 percent of a width of the shingle or any sub-range thereof.

A radius of the bend formed in the shingle 200 when applied over the hip or ridge of the roof 100 varies based on the pitch of the sides of the roof 100. The shingles 200 will be bent more and with a smaller bend radius to cover the ridge of a steep roof, and will be bent less with a larger bend radius to cover the ridge of a shallow roof. As the shingle 200 is bent, the overlay sheet 210 may shift relative to the underlay sheet 220 as the bend radius for each sheet is slightly different, and the length along the arc formed by the bent shingle 200 varies with the difference in radius. Consequently, the underlay sheet 220 shifts outward from the center of the bend in the shingle 200 relative to the overlay sheet 210 as the shingle 200 is bent. The attachment portion that attaches the overlay and underlay sheets 210, 220 to each other allows movement between the sheets 210, 220. In some embodiments, the overlay and underlay sheets 210, 220 are attached in a center portion of the shingle 200 to allow movement between the sheets 210, 220 when the shingle is bent. In some embodiments, a flexible adhesive is used to allow for relative movement of the sheets 210, 220 without separation.

The shingle strip 400 may be cut along cuts 402 to form one or more hip and ridge shingles 200, 300, described above. Cutting the shingle strip 400 along the cuts 402 may be performed manually or may be performed online, without removing the shingle strip 400 from the manufacturing line. Cutting the shingle strip 400 into individual shingles 200, 300 online reduces the time, cost, and capital investment needed to make individual hip and ridge shingles 200, 300. In some embodiments, the tabs 418 and cut-outs 422 are uniform in size so that each cut produces a uniform individual hip and ridge shingle 200, 300. (As opposed to the illustrated, non-uniform shingle.) The tabs 418 and cut-outs 422 can be any size or shape desired in the individual shingles 200, 300.
