I was thinking more along the lines of the outer seal is gonna leak, so make sure there's an inner seal to trap the water when it does.
Maybe there's a gasket on the part of the roof that raises, but make sure that if it leaks, it doesn't find some hole in the roof to collect in, or a way to get to the insulation/wiring. The best way I can think of would be a solid metal L-channel on the roof so that the water can't run down and in to the bus.
