A multi-tile system for attachment to a mounting surface is provided. Each of the tiles includes an upper edge configured to be oriented upward relative to the mounting surface and a lower edge configured to be oriented downward relative to the mounting surface. The tiles include a receiving member formed on an exterior side of the upper edge and a locking member formed on an interior side of the lower edge. The receiving member of the tile is configured to interlock with the locking member of an adjacent tile to limit movement of the lower edge of one tile away from the upper edge of the other tile. The receiving member and the locking member are configured to define a vertical range of continuous vertical adjustment between adjacent tiles.
