Benefits of technology
This patent describes a shingle blank that is coated with asphalt and has a prime region. The asphalt coating includes an upper section and a lower section, and a web is applied to the lower section. The shingle blank also has at least one perforation line that helps separate the blank. The invention also provides a method of manufacturing the shingle blank and a method of installing it on a roof. The technical effects of this invention include improved durability and flexibility of the shingle blank, as well as easier installation on a roof.
Problems solved by technology
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.

Embodiment Construction
[0021]The description and drawings disclose a substantially storm-proof hip and ridge roofing material for a roofing system. With reference to FIG. 1, a building structure 10 is shown having a shingle-based roofing system 12. While the building structure 10 illustrated in FIG. 1 is a residential home, it should be understood that the building structure 10 can be any type of structure, such as a garage, church, arena or commercial building, having a shingle-based roofing system 12.
[0022]The building structure 10 has a plurality of roof planes 14a-14d. The term “roof plane” as used herein is defined to mean a plane defined by a flat portion of the roof formed by an area of roof deck. 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 FIG. 1 have their respective illustrated slopes, it should be understood that the roof planes 14a-14d can have any suitable slope....

Abstract
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.
Description
TECHNICAL FIELD[0001]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 INVENTION[0002]Asphalt-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.[0003]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, hail...
