Benefits of technology

The patent is about improving shingles by making them stronger, more stable, and easier to pack. The goal is to create a shingle system that is space-efficient, prevents unintended adhesion, and promotes strong bonds.

Problems solved by technology

If the adhesion is too weak, a shingle may become loose and may result in structural instability of an entire roofing system.
Structurally unstable roofing systems may create hazardous conditions for occupants in the building on which the roofing system is assembled.
Structurally unstable roofing systems may also be costly to repair.
Shingles with weak sealants also may not be appropriate for roofing structures with steep slopes or roofing systems that may often be subjected to strong winds or high heat conditions.
Assemblies may not be packaged in the most secure or space-efficient manner.
Inefficient usage of space may increase packaging costs and shipping costs.
Improperly secured shingles may be damaged during shipping.
Another problem that occurs in packaging of shingles is that a sealant of a shingle may be inadvertently exposed to another surface during packaging or while inside the packaging.
Inadvertent exposure may result in a sealant adhering to an undesired surface.
As a result, an adhesive quality of a sealant may be compromised and the shingle may become unusable.

specific example embodiments

[0057]Specific example embodiments of a shingle with dual sealants are illustrated in FIGS. 1-7. FIG. 1A illustrates a top view of shingle 101 according to an example embodiment of the disclosure. FIG. 1B illustrates a back view of shingle 101 shown in FIG. 1A. Shingle 101 may comprise headlap region 102 and buttlap region 104. Headlap region 102 may comprise top headlap surface 106 and opposite-facing back headlap surface 108. Buttlap region 104 may comprise top buttlap surface 110 and oppositely facing back buttlap surface 112. As seen in FIG. 1A, top headlap surface 106 may include sealant 111 and tape 114. As seen in FIG. 1B, back headlap surface 108 may include tape 116. Back buttlap surface 112 may comprise sealant 113 positioned along the lower edges of tabs 118. As seen in FIG. 1A and FIG. 1B, in some embodiments, sealant 111 and sealant 113 may have substantially stripe-shaped geometries. In some embodiments, sealant 111 and sealant 113 may have the same shape and size.

Abstract

The present disclosure relates, according to some embodiments, to articles, systems, methods of use, methods of manufacturing, and methods of packing roofing shingles with dual sealants. A shingle may comprise, in some embodiments, a headlap region comprising a top headlap surface and a back headlap surface; a buttlap region comprising a top buttlap surface and a back buttlap surface. A top headlap surface may comprise a first sealant and / or a back headlap surface may comprise a second sealant.

Description

FIELD OF THE DISCLOSURE[0001]The present disclosure relates, in some embodiments, to articles, systems, and methods for roofing a structure including, for example, shingles comprising a first and second sealant.BACKGROUND OF THE DISCLOSURE[0002]Roofing materials such as shingles may be used to clad a structural surface such as a roof with a roofing substrate. Such shingles may have a sealant that allows a shingle to adhere to another shingle, a structure, or a substrate. If the adhesion is too weak, a shingle may become loose and may result in structural instability of an entire roofing system. Structurally unstable roofing systems may create hazardous conditions for occupants in the building on which the roofing system is assembled. Structurally unstable roofing systems may also be costly to repair. Shingles with weak sealants also may not be appropriate for roofing structures with steep slopes or roofing systems that may often be subjected to strong winds or high heat conditions.[...
