摘要
A roofing system has metal shingles that have formed side lap features that are configured to facilitate alignment of adjacent side lapped metal shingles of a shingle installation along a roofing structure and that couple the metal shingles together and form seals along their side lapped peripheral edges. The metal 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.
