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.
