Metal roofing shingles with alignment, sealing and aesthetic features

Abstract

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:
 a substrate;   a plurality of metal roofing shingles positioned over the substrate, wherein at least some of the plurality of metal roofing shingles comprise:
 a body having a top surface, a bottom surface, a forward edge, a rear edge, and side edges; 
 a headlap feature defined along the forward edge and configured to engage with 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 each of the side edges of the body and configured to attach to and lie substantially flat against a corresponding side lap feature of an adjacent metal roofing shingle in a same horizontal course of the metal roofing shingles; and 
   a standing seam feature positioned over a seam defined between each metal roofing shingle and 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 the adjacent metal roofing shingle after installation of the metal roofing shingle and adjacent roofing shingle along the substrate.
