Am I obligated to do this?

You're never obligated to do anything for anyone. The decision is 100% upon your shoulders and in your control.

That being said, given that this bothers you enough to post it, you're likely better off doing it.

I agree with Yugoslav (whom by the way I've noticed just today gives really good advice in very short posts).

Is your roommate a pretty good guy? If so, do it, because it's good to have favors owed to you by good people. You'll need one one day.
