Hip And Ridge Roofing Material
A shingle blank is provided comprising a substrate coated with an asphalt coating and configured to include a prime region. The asphalt coating includes an upper section and a lower section, the upper section is positioned above the substrate and the lower section is positioned below the substrate. A web is applied to the lower section of the prime region. At least one perforation line is positioned in the shingle blank. The at least one perforation line is sufficient to facilitate separation of the shingle blank.
This invention relates to asphalt-based roofing materials. More particularly, the invention pertains to hip and ridge roofing material having improved durability and impact resistance to withstand the destructive forces of storms.
BACKGROUND OF THE INVENTIONAsphalt-based roofing materials, such as roofing shingles, roll roofing, and commercial roofing, are installed on the roofs of buildings to provide protection from the elements. Typically, the roofing material is 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.
The typical roofing material construction is suitable under most circumstances. However, sometimes a roofing material is subjected to environmental conditions that may damage the roofing material. For example, storms are responsible for billions of dollars in damage to roofing materials every year. During storms, hailstones may impact the roofing material, which may cause tears or punctures in the roofing material. The hailstone impacts may also cause an immediate loss of some granules from the impacted areas of the roofing material and a further loss of granules from those areas over time.
The loss of granules creates an unattractive appearance and leaves the asphalt coating in those areas unprotected from the degrading effects of the elements.
Roofing materials are applied to roofs having various surfaces formed by roofing planes. The various surfaces and roofing planes form intersections, such as hips and ridges. Hips are formed by the intersection of two sloping roof planes running from a ridge to the eaves. A ridge is the uppermost horizontal intersection of two sloping roof planes. It would be desirable to improve the roofing material used for hips and ridges to have an improved ability to withstand the destructive forces of storms.

Each of the roof planes 14a-14d has a slope. The term “slope” as used herein is defined to mean the degree of incline of the roof plane. While the roof planes 14a-14d shown in
The building structure 10 is covered by the roofing system 12 having a plurality of shingles 20. In the illustrated embodiment, the shingles 20 are a storm proof, asphalt-based roofing material of the type disclosed in U.S. Pat. No. 6,709,994 to Miller et al., which is incorporated by reference, in its entirety. As shown in

Optionally, a stabilizer can be added to the protective coating 40 to tailor the protective coating 40 to specialized conditions, such as extreme exposures of ultraviolet light, solar radiation, and/or temperature. The protective coating 40 can also contain other additives, such as algaecides, fungicides, or pigments.

The process and apparatus to manufacture the shingle blank 26 is described in the '994 patent to Miller et al. and is only summarized herein. Referring now to
In a first step of the manufacturing process, the continuous sheet 72 of substrate is payed out from a roll 74. The substrate can be any type known for use in reinforcing asphalt-based roofing materials, such as a nonwoven web, scrim or felt of fibrous materials, such as glass fibers, mineral fibers, cellulose fibers, rag fibers, mixtures of mineral and synthetic fibers, or the like. Combinations of materials can also be used in the substrate. The sheet 72 of substrate is passed from the roll 74 through an accumulator 76. The accumulator 76 allows time for splicing one roll of substrate to another, during which time the substrate within the accumulator 76 is fed to the manufacturing process so that the splicing does not interrupt manufacturing.
Next, the sheet 72 is passed through a coater 78 where an asphalt coating 46 is applied to the sheet 72 to completely cover the sheet 72 with a tacky coating. The asphalt coating 46 can be applied in any suitable manner, such as for example, spraying or rolling the asphalt coating on to the sheet 72. Coating the sheet 72 with the asphalt coating 46 forms coated sheet 80.
The term “asphalt coating” means any type of bituminous material suitable for use on a roofing material such as asphalts, tars, pitches, or mixtures thereof. The asphalt can be either manufactured asphalt produced by refining petroleum or naturally occurring asphalt. The asphalt coating 46 can include various additives and/or modifiers, such as inorganic filters, mineral stabilizers, or organic materials, such as polymers, recycled streams, or ground tire rubber.

In the illustrated embodiment, webbed sheet 98 is passed between backing roller 99a and press roller 99b. The rollers, 99a and 99b, are configured to compress the webbed sheet 98 sufficient to embed the granules 42 into the webbed sheet 98. Passing the webbed sheet 98 through the backing roller 99a and the press roller 99b forms embedded sheet 100.
Referring again to
The cooled sheet 102 is passed through applicators 104 and 105. The applicators, 104 and 105, are configured to apply a sealant to the surfaces of the cooled sheet 102. The applicators, 104 and 105, can be any suitable mechanism for applying the sealant to the cooled sheet 102. In the illustrated embodiment, the applicator 104 applies the sealant to the top surface of the cooled sheet 102 and the applicator 105 applies the sealant to the bottom surface of the cooled sheet 102. In other embodiments, the sealant can be applied to just the top or bottom surfaces of the cooled sheet 102. Application of the sealant to the cooled sheet 102 forms sealed sheet 107.
The sealed sheet 107 is passed through cutting roller 108a and anvil roller 108b. In the illustrated embodiment the rollers, 108a and 108b, are configured to perform several manufacturing operations. First, the cutting roller 108a and the anvil roller 108b are configured to form the perforation lines, 60 and 62, having the perforations 64. As discussed above, the perforations 64 can have any desired configuration and the perforation lines, 60 and 62, can be positioned anywhere along the length L of the shingle blank 26. The cutting roller 108a includes a plurality of perforating knives 109 spaced apart along a tangential line. The perforating knives 109 rotate with the rotation of the perforating roller and form the perforations 64 upon contact with the sealed sheet 107. Second, the cutting roller 108a and the anvil roller 108b can be configured to form the notches, 161a and 161b, formed in the prime region 130 of the shingle blank 126 as shown in
