You might consider putting a big tarp (or huge piece of plastic up over the entire ceiling in the room that leaks, with one end of it (the point where the water empties from it) a little lower and into a big plastic garbage barrel. that way, whenever it leaks, no matter where it leaks from, it all ends up in the same barrel. To empty the barrel, run a garden hose out the window. No lifting, all the water ends up in the same place.
