Spray some light lubricant (WD-40, Liquid Wrench, garage door spray lube, etc.) on the hinges and where the roller shafts - not on the rolling surfaces or the tracks. That should help a bit. Also a bit on the springs and the support bearings for the spring shaft wouldn't hurt.
You might want to lube the drive mechanism (chain, screw drive) as well. Some of the noise could be coming from there as well.
