On the AC's I've installed there are four long lag bolts that screw up through the ceiling assembly in each corner into the upper unit and tighten down a foam compression seal. If you remove the ceiling unit carefully this compression seal should be stuck to the roof membrane and hold the upper unit in place. The roof material was probably cut out in an X pattern and the corners stapled down to the roof trusses and may be in the way but it wouldn't hurt to trim it back.
On my Voltage the main AC screws down from the top, but I believe the garage and bedroom AC's have the lag bolts from underneath.
