Abstract
A roofing system including a cap shingle and methods of producing a cap shingle and forming a roof are disclosed. In one embodiment, the cap shingle can include at least one layer of shingle material including an upper surface having a headlap portion and an exposure portion, and a lower surface. A sealant can be applied along the lower surface and a sealant attachment zone can be positioned along the upper surface of the at least one layer of shingle material between the headlap and exposure portions. The sealant attachment zone can be configured to contact a sealant applied along a lower surface of a next cap shingle to promote adhesion between the cap shingles installed along a ridge, hip, or cap of the roof.
