Roof A/C is generally not centered over the hole, but rather, offset, so there is a good overhang of the heaviest part of the unit, aft of the hole. Usually, there are two or more rubber blocks, the same fairly dense material the gasket is made from, glued to the bottom of the A/C. If these blocks are not present, the heavy overhang will sag and can touch the roof. It sounds like the OP installed wedges to space the unit up level, like the original rubber blocks would have. They must be missing.
