Shingle with dual sealant

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.[...

AI Technical Summary

Benefits of technology

[0004]Accordingly, a need has arisen for improved shingles that have greater bond or sealant strength, increased stability, and greater ease and space-efficiency in packaging. More specifically, it may be desirable to have a shingle assembly that promotes space-efficient packaging and prevent inadvertent adherence of a sealant to an undesired surface. It may also be desirable to have a shingle system wherein shingles may form strong bonds or a strong adhesion.

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.
