Garage door lube and tune
Garage door rattles or vibrates when it runs?
Rattles are usually loose bolts and fittings or a worn opener mount, not a failing door. A tune-up that tightens hardware, lubricates and re-balances tends to quiet it down.

Is this what you're seeing?
The door shakes or buzzes in the track as it travels.
You hear a rattle in the ceiling when the opener runs.
Vibration comes through the wall or the room above the garage.
The noise began after a cold snap or a long time without service.
Something metallic clicks or ticks at the same point each cycle.
What's going on
Garage doors shake themselves loose. The door is a long assembly of bolts, nuts, brackets and hinges, and each cycle puts small vibration into every fastener. After a few years, nuts on the opener bracket, the track brackets, the hinges and the trolley start to back off, and a loose one will rattle in rhythm with the door.
Where the sound sits points to the cause. A rattle high up is usually the opener mounting to the ceiling, or loose opener rail brackets, or a slack chain. A rattle running along the side is a loose track bracket, a worn roller rattling in its track or a loose hinge. A rattle right at the middle of the door can be a loose strut. A buzz in the wall is the opener transmitting through framing.
Cold weather makes it worse, since metal shrinks and grease stiffens. The door will also rattle more if the track is slightly out of alignment or the springs are out of balance, which loads the opener harder. A door that has been rattling for months often has hardware that has already worn into the holes.
What to do right now
Do
Check opener ceiling brackets and the rail bolts, and snug anything finger loose.
Check that the opener chain or belt is not sagging.
Check the hinge screws and track bracket bolts on the closed door by eye.
Note where in the door travel the rattle happens.
Don't
Do not tighten the bottom bracket or the cable and spring hardware, those are under tension.
Do not over-tighten the opener bolts to stop the sound, you can strip the mount.
Do not loosen track bolts to shift the track.
Do not use a grease on rollers or track.
How we fix it
This is a garage door lube and tune. We tighten every fastener we can safely reach, replace stripped hardware, lubricate the moving points, adjust the opener chain or belt, and test the door balance. Then we run the door again to confirm the rattle is gone.
Repair or replace?
Rattles are almost always a tune-up. If the rollers are worn, the track is out of position or the hinges are cracked, then a garage door repair is needed.
If the opener itself has become loud and shaky, a quieter belt-drive opener is worth a conversation, especially with a bedroom over the garage.
