Multi-layered cap shingle with enhanced wind performance and method of making same

A roof, comprising:

• a ridge, hip or cap;
• a plurality of cap shingles configured to be installed over the ridge, hip, or cap of the roof;
• wherein each of the cap shingles comprises:
• a plurality of layers, including:
• a top layer having opposite side edges, an exposure area, and a headlap area;
• wherein the top layer is configured to bend in an arc having a first radius for installation of the cap shingle, along a ridge, hip, or rake of a roof;
• and
• a bottom layer having opposite side edges substantially aligned with the opposite side edges of the top layer;
• and
• an adhesive applied between a lower surface of the top layer and an upper surface of the bottom layer so as to bottom layer and the top layer together;
• and
• wherein the bottom layer is configured to bend in an arc having a second radius that is different from the first radius, and with the first and second edges of the bottom layer remaining in a substantially fixed alignment with respect to the first and second edges of the top layer during installation of the cap shingle, along the ridge, hip, or rake of the roof.

A cap shingle, comprising:

• a plurality of layers, including:
• a top layer of shingle material having a front edge, a back edge, first and second side edges, a lower surface, and an upper surface having an exposure area and a headlap area;
• wherein the top layer is configured to bend in an arc having a first radius for installation of the cap shingle, along a ridge, hip, or rake of a roof;
• and
• a bottom layer of shingle material having a lower surface, an upper surface, a front edge, a back edge, a first side edge substantially aligned with the first side edge of the top layer, and a second side edge substantially aligned with the second side edge of the top layer;
• an adhesive applied between the lower surface of the top layer and the upper surface of the bottom layer;
• wherein the adhesive is applied adjacent to the aligned first and second side edges of the top layer and bottom layers so as to attach the first and second side edges of the bottom layer to the first and second side edges of the top layer;
• and
• a sealant applied to the lower surface of the bottom layer for sealing the cap shingle to an adjacent cap shingle installed along the ridge, hip, or rake of the roof;
• and
• wherein the bottom layer is configured to bend in an arc having a second radius that is different from the first radius with the first and second edges of the bottom layer remaining in a substantially fixed alignment with respect to the first and second edges of the top layer during installation of the cap shingle, along the ridge, hip, or rake of the roof.

• and
• wherein the bottom layer is configured to bend in an arc having a second radius that is different from the first radius, such that the first and second edges of the bottom layer remain in a substantially fixed alignment with respect to the first and second edges of the top layer during installation of the cap shingle, along the ridge, hip, or rake of the roof.
