Two possibilities....
- bearing on fan motor - put a few drops of oil on it
-The fan blades are hitting the housing - if there is a set screw on the fan you can move it.
It may not be as loud to your neighbors as you think, you could run it a while and see if it gets worse or not. Then take it to dealer later.
If you do not want to run it anymore, your rooftop A/C may have a heat pump or heat strip to keep you warm.
