I would push this preflop versus a lot of players. Roothlus has a reputation for being a nit, and he is expecting loose action at this stage of the 5r, so I would expect he probably has JJ+, AK.

If you flat call, you obviously can't fold every time you miss a set. You generally want to get it in of an OESD and maybe on a gutshot. On a low flop, you want to get a read. If you think villain has high cards, you don't have to fold.
