Metal roofing shingles with alignment, sealing and aesthetic features
A roofing system has metal roofing shingles that have formed side lap features that are configured to facilitate alignment of adjacent side lapped metal roofing shingles of a shingle installation along a roofing structure and that couple the metal roofing shingles together and form seals and seams along their side lapped peripheral edges. The metal roofing shingles also can have alignment features that cooperate to align shingles in one course with shingles in a next lower course within their headlap regions. The roofing system also has standing seam features configured to couple to the metal roofing shingles to cover the formed seams.
1. A roof structure, comprising:

at least one side lap feature defined along each of the side edges of the body, wherein the at least one side lap feature of each metal roofing shingle is substantially flat and is configured to attach to and lie substantially flat against a corresponding side lap feature of an adjacent metal roofing shingle in a horizontal direction along a same course of metal roofing shingles, with the bottom surface of the at least one side lap feature and lying substantially flat against a top surface of the corresponding side lap feature of the adjacent metal roofing shingle to connect the metal roofing shingle and the adjacent metal roofing shingle together along the substrate and define a seam along an area of overlap therebetween; and
a standing seam feature positioned over the seam defined between each metal roofing shingle and adjacent metal roofing shingle;
wherein the standing seam feature is separate from each metal roofing shingle and is positioned over and attached to the top surfaces of the metal roofing shingle and adjacent metal roofing shingle after installation of the metal roofing shingle and adjacent roofing shingle along the substrate; and
wherein the at least one side lap feature defined along each side edge extends substantially along an entire length of the side edge.
2. The roof structure of claim 1 , wherein the standing seam feature comprises a substantially square, rectangular, U-shaped, domed or arched configuration.

5. The roof structure of claim 1 , further comprising an adhesive material applied along a surface of each metal roofing shingle adjacent one or more of the peripheral edges thereof.
6. The roof structure of claim 5 , wherein the adhesive material comprises a bead, strip, or patterned arrangement of a pressure sensitive sealant material with a release material covering strip applied thereto.
7. The roof structure of claim 1 , further comprising an adhesive material applied along an area of overlap between a portion of the standing seam feature and each of the metal roofing shingle and the adjacent metal roofing shingle and configured to attach the standing seam feature to each of the metal roofing shingle and the adjacent metal roofing shingle.
8. The roof structure of claim 1 , wherein the at least one side lap feature of the metal roofing shingle and the corresponding side lap feature of the adjacent metal roofing shingle are configured to engage along the area of overlap, and further comprising an adhesive material applied along the area of overlap.
9. The roof structure of claim 1 , wherein the at least one side lap feature comprises slanted or angled projections or tabs positioned along the body of each metal roofing shingle.
10. The roof structure of claim 9 , wherein the projections or tabs are configured to bend in upward or downward directions.
11. The roof structure of claim 1 , further comprising at least one slot or cut-out formed along the at least one side lap feature of each of the metal roofing shingles, and wherein the at least one side lap feature of each metal roofing shingle and adjacent metal roofing shingle interlock together in a compressive fitted engagement.
12. The roof structure of claim 1 , further comprising an underlayment material positioned between the metal roofing shingles and the substrate.
13. The roof structure of claim 1 , wherein the headlap features of the metal roofing shingles each comprise at least one interlocking feature configured to interlock with an interlocking feature of a headlap feature of a metal roofing shingle in a higher or lower course of metal roofing shingles.
14. The roof structure of claim 13 , wherein the at least one interlocking feature comprises one or more tongue and groove features, serrations, hooked features, domed or arched features, ridges, projections, tabs, or combination thereof.
15. A roof structure, comprising:
a substrate;
a plurality of metal roofing shingles positioned over the substrate, each of the metal roofing shingles comprising:
a top surface, a bottom surface, a forward edge, a rear edge, and side edges;
headlap features defined along the forward and rear edges;
wherein a headlap feature defined along the forward edge of each metal roofing shingle of a higher course of roofing shingles is configured to engage a corresponding headlap feature defined along the rear edge of at least one metal roofing shingle of a lower course of metal roofing shingles; and
at least one side lap feature defined along substantially along an entire length of each side edge of each metal roofing shingle;
wherein the at least one side lap feature of each metal roofing shingle is configured to overlap and lie substantially flat against a corresponding side lap feature of a horizontally adjacent metal roofing shingle in a same course of metal roofing shingles, with the bottom surface of the metal roofing shingle lying substantially flat against an upper surface of the horizontally adjacent metal roofing shingle to connect the metal roofing shingle and the horizontally adjacent metal roofing shingle together along the substrate and define a seam along an area of overlap therebetween;
wherein when the metal roofing shingles are installed over the substrate, the at least one side lap feature and the corresponding side lap feature overlapped thereby are substantially parallel to the substrate; and
a standing seam feature positioned over the seam defined between each metal roofing shingle and horizontally adjacent metal roofing shingle; and
wherein the standing seam feature is separate from each metal roofing shingle and is positioned over and attached to the top surfaces of the metal roofing shingle and horizontally adjacent metal roofing shingle after installation of the metal roofing shingle and the adjacent roofing shingle along the substrate.
16. The roof structure of claim 15 , wherein the headlap features of the metal roofing shingles comprise at least one interlocking feature configured to interlock with an interlocking feature of a headlap feature of a metal roofing shingle in the lower course of metal roofing shingles.
