If the rollers or other parts seem stuck, you can try brushing on some kerosene to the parts. If they are rusty, use steel wool to take away the rust and lubricate as usual. If they are badly corroded they may need replacement. You also need to take a look at the opener. If it is operated by a drive screw or a chain, you may need to lubricate these parts as well.
Garage doors and gates over time will require repairs and even replaced parts because of the wear and tear that is normal with them. Opening and closing a garage door will weaken the tension springs that control the door itself. Other things that are normal and will need repair is the motor it self that opens and closes garage doors or even a gate.
They are resistant to sagging over time, and will not warp due to time. Steel will also hold in heating and air much better than other garage doors. There are also specific openers that are sold for steel garage doors because they can be relatively heavy to an aluminum or wood application. Aluminum and wood doors are very cost efficient and do not require a high horsepower motor to raise them and close them.
High efficiency motors and garage doors are now sold which are becoming a popular replacement for old hardware and old, heavy models. There are many different types of garage doors a home owner or even a storage business can choose from, and each of them represent different advantages. For example, steel doors are very durable, and can expect to last a very long time.
