If you are having that much issue it is time to replace the door and inspect the opening before putting in a new door. That is a pretty old aluminum door by all appearances.

Thank you for your time to type out your reply, but my question was on what are my options to remove the door, not if i should buy a new door.

I am looking for solution that would be less damaging to door or frame so that I can still use it for some time. I am thining about cutting off one of the sides of top rail that holds door in place. After I will change rollers I would attach that side back somehow

Hi, Maybe the frame is sagging. If you have a power drill, Get some fender washers that fit in the channel and Sheet rock screws about 1 1/2 long and start from each end and screw the fender washes up, Mabe it may do the trick and pull the channel up.

'm not sure how to help you get the door out, but I would be concerned about the sagging frame. We had a similar issue - caused by a leak under the door, which seeped into the wall below. The door had to come out and the wall repaired. It was a pretty big job, but it would have been a lot worse if we hadn't fixed it when we did. And yes, we replaced the door.

I hope this isn't your problem with the door frame.

I would be more concerned as to why the door is sagging. Is there no header above it, and house is pressing down on the door (not a good thing at all), or is their rot underneath it, so the whole door is dipping downward. Even if you are not replacing the door, the repairs to get it all level, are more important than new rollers.

Water leak?

+1 to previous comments. There are bigger issues here. Those penetrations in the wall above the door as well as the siding are indicative of a larger issue. Need to do some investigation here...and pronto.

This job starts with unzipping that siding and checking the status of the header. The sag is worrisome.
