A sheet metal exterior sheathing element particu1arly suitable as a roofing tile. The tile has inter-engageable channels on its opposing longitudinal sides, one channel (6, 7) being on the underside and the channe l (9) on the upperside of the tile. A mounting tab (10) extends from adjacent the upperside channel (9) substantially co-p1anar to the body of the tile. The channels enable two tiles (1a, 1b) to be joined in an over1apping side by side re1ationship with their corresponding channel sections engaged. Each tile (1a, 1b) can be fixed to a supporting structure by their mounting tabs (10). A third tile (1c) can then be joined longitudinally of the first two tiles (1a, 1b) by engaging its underside channel (6) over and about their joined upperside channel sections (9). It can also be fixed to the supporting structure and the steps repeated to sheath a desired area.
