You need your garage door to operate as expected. You want it to be reliable and safe. The fact that the garage door opens above you and you then pull your car, walk, and even stand right under its weight can be concerning, and this is why you need to stay on top of maintenance and repair issues. Here are some concerns you should maintain about your garage door, which can help you recognize areas that may soon require maintenance and/or repairs.
The garage door rollers can come off the tracks
The rollers that travel along the tracks can come off of them if something is going on, like if there is dirt collected on the tracks, they are damaged, or they haven't been lubricated properly. Some issues, such as cleaning the tracks, you can do yourself. For others, like damage, you want someone to repair the problem. If the rollers come all the way off the tracks, then the garage door won't open or close, and that can cause the door to fall.
Parts can come loose on the garage door
Just about any part of the garage door that's bolted, hinged, or screwed or that moves can end up coming loose. When something like this does happen, it might end up causing some rougher movement and some noise. However, ignoring the problem will only allow the loose parts to continue getting looser until they lead to any number of malfunctions, some of which can be dangerous. Also, when one loose part is ignored, it can cause vibrations that cause others to follow suit. If you have any reason to believe something needs tightening and you can't find the exact source, can't reach it, or don't feel it's safe for you to fix, then you want to call someone out to do it.
Cables can wear out
Another common issue that a garage door can have as time goes on is that the cables can get worn out. If you see the cables are fraying, then you never want to ignore this, as ignoring it can cause more problems. When a cable finally snaps, an excessive amount of stress is put on the remaining cable. This can make the door do everything from moving unevenly and even getting stuck in a crooked position. It's best to completely replace any cable that's visibly starting to show wear.
