Description

BACKGROUND

Asphalt-based roofing materials, such as roofing shingles, roll roofing, and commercial roofing are installed on the roof of a building to provide protection from the elements. The roofing material may be constructed of a substrate such as a glass fiber mat or an organic felt, an asphalt coating on the substrate, and a surface layer of granules embedded in the asphalt coating.

Roofing materials are applied to a roof having various surfaces formed by roofing planes. The various surfaces and roofing planes include edges and intersections, such as, for example, hips, ridges, eaves, rakes, and valleys. During installation of roofing shingles on a roof, starter shingles and hip and ridge shingles are often used to cover the edges and intersections of a roof.

SUMMARY

The present application discloses a shingle blank, such as, for example, a shingle blank that can be separated into either starter shingles or hip and ridge shingles.

An exemplary shingle blank includes a substrate coated with asphalt, a headlap portion, a prime portion, a starter shingle separation line, and first and second ridge shingle separation lines. The headlap portion has a first sealant that extends along the width of the substrate, and the prime portion has a second sealant that extends along the width of the substrate. The starter shingle separation line extends along the width of the substrate, substantially bisects the substrate, and facilitates separation of the shingle blank into first and second starter shingles. The first starter shingle includes the first sealant and the second starter shingle includes the second sealant. The first and second ridge shingle separation lines extend along the height of the substrate from an upper edge of the substrate to a lower edge of the substrate, substantially divides the substrate into three equally sized parts, and facilitates separation of the shingle blank into three ridge shingles. Each of the three ridge shingles includes a portion of the first sealant and a portion of the second sealant.

Another exemplary shingle blank includes a substrate coated with asphalt, a headlap portion, a prime portion, a starter shingle separation line, and first and second ridge shingle separation lines. The headlap portion has a first sealant that extends along the width of the substrate, and the prime portion has a second sealant that extends along the width of the substrate. The starter shingle separation line extends along the width of the substrate and facilitates separation of the shingle blank into first and second starter shingles. The first starter shingle includes the first sealant and the second starter shingle includes the second sealant. The first and second ridge shingle separation lines extend along the height of the substrate from an upper edge of the substrate to a lower edge of the substrate and facilitates separation of the shingle blank into three ridge shingles. Each of the three ridge shingles includes a portion of the first sealant and a portion of the second sealant.

An exemplary shingle blank includes a substrate coated with asphalt, a headlap portion, a prime portion, a starter shingle perforated line, and first and second ridge shingle perforated lines. The headlap portion has a first sealant that extends along the width of the substrate, and the prime portion has a second sealant that extends along the width of the substrate. The starter shingle perforated line extends along the width of the substrate, substantially bisects the substrate, and facilitates separation of the shingle blank into first and second starter shingles. The first starter shingle includes the first sealant and the second starter shingle includes the second sealant. The first and second ridge shingle perforated lines extend along the height of the substrate from an upper edge of the substrate to a lower edge of the substrate, substantially divides the substrate into three equally sized parts, and facilitates separation of the shingle blank into three ridge shingles. Each of the three ridge shingles includes a portion of the first sealant and a portion of the second sealant. The first and second sealants are parallel to the starter shingle perforated line.

The description and drawings disclose a shingle blank that can be separated into both starter shingles and hip and ridge shingles. With reference to FIG. 1, a building structure 100 is shown with a roofing system comprising shingles 102. While the building structure 100 illustrated in FIG. 1 is a residential home, it will be understood that the building structure 100 may be any type of structure, such as, for example, a garage, church, arena, or commercial building.

The building structure 100 has a plurality of roof planes 104a-104f. The term “roof plane” as used herein is defined as a plane or flat portion of the roof formed by an area of roof deck. Each of the roof planes 104a-104f has a slope. The term “slope” as used herein is defined as the degree of incline of the roof plane. While the roof planes 104a-104f shown in FIG. 1 have their respective illustrated slopes, it will be understood that the roof planes 104a-104f may have any suitable slope.

The roof of the building structure 100 may include any combination of hips 106, ridges 108, eaves 110, rakes 112, and valleys 114. The term “hip” as used herein is defined as the inclined external angle formed by the intersection of two sloping roof planes. For example, a hip 106 is illustrated at the intersection of roof planes 104b and 104c, and at the intersection of roof planes 104c and 104d. The term “ridge” as used herein is defined as the uppermost, horizontal external angle formed by the intersection of two sloping roof planes. For example, a ridge 108 is illustrated at the intersection of roof planes 104a and 104f, the intersection or roof planes 104b and 104d, and at the intersection of roof planes 104d and 104e. The term “eave” as used herein is defined as the horizontal, lower edge of a sloped roof. For example, an eave 110 is illustrated at the lower edge of roof planes 104a, 104b, and 104c. The term “rake” as used herein is defined as the inclined edge of a sloped roof over a wall from the eave to the ridge. For example, rakes 112 are illustrated at the inclined edge of sloped roof planes 104a and 104f over wall 116. The term “valley” as used herein is defined as the internal angle formed by the intersection of two sloping roof planes to provide water runoff. For example, a valley 114 is illustrated at the intersection of roof planes 104a and 104b.

The building structure is covered by a roofing system comprising a plurality of shingles 102. The shingles 102 are installed on the various roof planes 104a-104f in a generally horizontal course in which the shingles 102 overlap the shingles 102 of a preceding course. Any suitable design for a shingle 102 may be utilized. In covering a roof, different types of shingles may be used, such as, for example, conventional shingles (e.g., strip, three-tab, laminated), starter shingles, and hip and ridge shingles. Conventional shingles cover a majority of a roof plane 104a-104f However, other types of shingles provide preferred qualities at the intersections between roof planes 104a-104f and at the edges of roof planes 104a-104f For example, because shingles 102 overlap each other, a roof is covered with two layers of shingles 102, but the intersections between roof planes 104a-104f and edges of the roof planes 104a-104f may have only a single layer of shingles. In order to make the shingles consistent throughout the roof and to provide an additional layer of protection against outside elements at the edges and intersections, starter shingles and hip and ridge shingles may be utilized.

Starter shingles may be installed along the eaves 110 or any other area of a roof where a starter shingle is needed. After starter shingles are installed, a first course of conventional shingles is secured to and installed over the starter shingles. The first course of conventional shingles may be secured to the starter shingles by, for example, an adhesive, a sealant on the starter shingle and/or the conventional shingle, and/or fasteners (such as a nail). After the first course of conventional shingles are installed, subsequent courses of conventional shingles are installed by offsetting and overlaying the subsequent courses over a portion of each previously installed course of conventional shingles toward the ridge 108 of the roof.

Hip and ridge shingles may be installed along the hips 106, ridges 108, or any other area of a roof where a hip and ridge shingle is needed. Hip and ridge shingles are installed in a manner that is well known in the art. The hip and ridge shingles are installed after the conventional shingles are installed up to the hip 106 or ridge 108 on both planes 104a-104f that form the hip 106 or ridge 108. The first hip and ridge shingle is bent over the lowest point of the hip 106 or one end of the ridge 108 and fastened to the conventional shingles on each side of the hip 106 or ridge 108. Subsequent hip and ridge shingles partially overlay each previous hip and ridge shingle, are bent over the hip 106 or ridge 108 and the conventional shingles on either side of the hip 106 or ridge 108, and are fastened to a previous hip and ridge shingle and the hip 106 or ridge 108. Hip and ridge shingles may be fastened to previous hip and ridge shingles and/or the hip 106 or ridge 108 by an adhesive, a sealant, and/or fasteners (such as a nail).

FIGS. 2A-2D are illustrations of a shingle blank 200 that can be separated into starter shingles or hip and ridge shingles. The shingle blank 200 is a substrate 201 coated with asphalt that includes a headlap portion 202, a prime portion 204, a starter shingle separation line 210, and a first and second ridge shingle separation line 212. The width W of the substrate 201 may be, for example, between about 36 inches and about 40 inches. The height H of the substrate 201 may be, for example, between about 11 inches and about 16 inches. In an exemplary embodiment, the height HH of the headlap portion 202 and the height PH of the prime portion 204 are substantially the same. In another embodiment, the height HH of the headlap portion 202 and the height PH of the prime portion 204 are different. For example, the height HE of the headlap portion 202 may be between about 6 inches and about 8 inches, and the height PH of the prime portion 204 may be between about 5 inches and about 6 inches, but at least one inch less than the height HE of the headlap portion 202. In certain embodiments, both the headlap portion 202 and the prime portion 204 are embedded with granules. Additionally, in some embodiments, the granules on the prime portion 204 of the shingle blank 200 are more aesthetically pleasing than the granules on the headlap portion 202 of the shingle blank 200.

The headlap portion 202 has a first sealant 206 extending along the width W of the substrate 201, and the prime portion has a second sealant 208 extending along the width W of the substrate 201. In the illustrated embodiment, the first sealant 206 and the second sealant 208 are disposed on the top surface of the substrate 201. In another embodiment, the first sealant 206 and the second sealant 208 may be disposed on the bottom surface of the substrate 201. In yet another embodiment, one of the first sealant 206 and the second sealant 208 may be disposed on the top surface of the substrate 201, and the other of the first sealant 206 and the second sealant 208 may be disposed on the bottom surface of the substrate 201.

The starter shingle separation line 210 extends along the width W of the substrate 201, substantially bisects the substrate 201, and facilitates separation of the substrate 201 into a first starter shingle 214 and a second starter shingle 216. The starter shingle separation line 210 is a line of weakness that may be in the form of a perforated line, a score, a mat cut with the asphalt holding the shingle blank 200 together, or any other form that facilitates separation of the shingle blank 200 into a first starter shingle 214 and a second starter shingle 216. The first starter shingle 214 includes the first sealant 206, and the second starter shingle 216 includes the second sealant 208. The first starter shingle 214 may include the headlap portion 202 of the shingle blank 200, and the second starter shingle 216 may include the prime portion 204 of the shingle blank 200, or vice versa. In certain embodiments, either the first starter shingle 214 or the second starter shingle 216 may include the entire prime portion 204 and a portion of the headlap portion 202. In an exemplary embodiment, the entire headlap portion 202 may be on one of the first starter shingle 214 and the second starter shingle 216.

The first and second ridge shingle separation lines 212 extend along a height H of the substrate 201 from an upper edge 218 of the substrate 201 to a lower edge 220 of the substrate 201. The first and second ridge shingle separation lines 212 divide the substrate 201 into three equally sized pieces and facilitate separation of the substrate 201 into three ridge shingles 222. The first and second ridge shingle separation lines 212 are lines of weakness that may be in the form of a perforated line, a score, a mat cut with the asphalt holding the shingle blank 200 together, or any other form that facilitates separation of the shingle blank 200 into three ridge shingles 222. After the substrate 201 is separated along the first and second ridge shingle separation lines 212, each of the ridge shingles 222 includes part of the headlap portion 202, part of the prime portion 204, a portion of the first sealant 206, and a portion of the second sealant 208.

In certain embodiments, the first sealant 206, the second sealant 208, or both sealants 206, 208 are parallel to the starter shingle separation line 210. Referring to FIG. 2A, both the first sealant 206 and the second sealant 208 may be located proximate to the starter shingle separation line 210. Referring to FIG. 2B, the first sealant 206 may be located proximate to the upper edge 218 of the substrate 201, and the second sealant 208 may be located proximate to the lower edge 220 of substrate 201. Referring to FIG. 2C, the first sealant 206 may be located proximate to the starter shingle separation line 210, and the second sealant 208 may be located proximate to the lower edge 220 of the substrate 201. Referring to FIG. 2D, the first sealant 206 may be located proximate to the upper edge 218 of the substrate 201, and the second sealant 206 may be located proximate to the starter shingle separation line 210.

FIG. 3A illustrates the shingle blank 200 after being separated into hip and ridge shingles 222. Each of the ridge shingles 222 includes part of the headlap portion 202, part of the prime portion 204, a portion of the first sealant 206, and a portion of the second sealant 208. In certain embodiments, both the headlap portion 202 and the prime portion 204 are embedded with granules. Additionally, in some embodiments, the granules on the prime portion 204 of the shingle blank 200 are more aesthetically pleasing than the granules on the headlap portion 202 of the shingle blank 200. During installation, the headlap portion 202 of the hip and ridge shingles 222 may be covered by an overlapping roofing shingle, and the prime portion 204 of the hip and ridge shingles 222 remains exposed.

FIG. 3B illustrates the shingle blank after being separated into a first starter shingle 214 and a second starter shingle 216. The first starter shingle 214 may include the headlap portion 202 of the substrate 201, and the second starter shingle 216 may include the prime portion 204 of the substrate 201, or vice versa. In certain embodiments, either the first starter shingle 214 or the second starter shingle 216 may include the entire prime portion 204 and a portion of the headlap portion 202. In an exemplary embodiment, the entire headlap portion 202 may be on one of the first starter shingle 214 and the second starter shingle 216. During installation, both the first starter shingle 214 and the second starter shingle 216 are covered by an overlapping roofing shingle.
