The battens are formed by folding the side edge portions of adjacent pan sections to form securing channels and upstanding side walls. The side walls are folded inwardly away from the securing channels and then downwardly to form downwardly projecting lips spaced inwardly and intermediate of the height of the side walls and a closure cap is slidable along the top edges of the side walls and in engagement with the downwardly projecting lips of adjacent pan sections to bridge and seal the gap formed between the adjacent side walls above the abutting securing channels, the securing channels being held down on the underlying roof structure by fastening screws.</p> |
