A metal roofing member 1 is disposed side by side with another metal roofing member on a roof base. The metal roofing member 1 has a box-shaped front substrate 10 made of a metal sheet, a rear substrate 11 disposed on the rear side of the front substrate 10, so as to cover an opening of the front substrate 10, and a core material 12 made from a foam resin and filled in between the front substrate 10 and the rear substrate 11. The front substrate 10 results from forming the metal sheet into a box shape. The front substrate 10 has a side wall portion that is continuous in the circumferential direction and is formed by performing drawing or bulging processing on the metal sheet. The front substrate 10 has a height of 4 mm to 8 mm.

Metal roofing includes metal roof-covering sheets or tiles having apertures along longitudinal end edges for coupling a pair of the sheets in an overlapping condition. One fastening arrangement comprises a fastener having a shaft extending in a longitudinal direction and fastening features at longitudinally spaced positions along the shaft. The fastening features may comprise a fastening peg or an opening receiving a fastening member therethrough. The pegs and openings may be combined in such a manner that at least two of the features cooperate with the apertures of the respective sheet in opposing transverse directions so as to longitudinally offset the apertures in the overlapping condition. Another fastening arrangement comprises a roof-covering sheet locating fastenings pegs which are spaced inward of the apertures in a longitudinal direction of the sheet so as to form the longitudinal offset between the respective sets of apertures.

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.

A lightweight interlocking metal roof capping system for installation onto a steep or inclined structure roof either directly over the roof decking material or over an existing shingle roofing system, with the metal roofing system installed from the roof ridgeline down to the drip edge of the roof gutter. Cooperating outwardly extending flanges and receiving pockets for capturing and interlocking the metal panels of the roofing system create an interlock between and among panel members with overlying edge ends configured to be resistant to lift up due to winds either across the roof or along the roof edges.
