How to Fix Rollers on a Garage Door

Save

If your roll-up garage door does everything but roll up or is having trouble rolling up, then it is time to fix it. The difficulty of the job will depend on what the issue is. Sometimes it is just a matter of cleaning and lubricating the tracks and rollers. Other times, you may need to replace the roller or hinge on the door. However, it is still a job that most people will be able to do with only minimal effort.

Things You'll Need

  • C-clamps Detergent 2 by 4s Wrench (size depends on garage door) Stepladder Lubricant spray or powdered graphite Household oil or silicone spray Level Hammer
  • Unplug the garage door opener before you begin if it is automatic.

  • Identify the parts of your roll-up garage door. The garage door uses rollers as a guide when it opens and closes. The rollers are attached to each side of the garage door with hinges. The rollers sit in a track. The track is attached to the garage frame with mounting brackets.

  • Clean both the tracks and the rollers with a household cleaner and water to remove any dirt or hardened grease. Wipe them dry.

  • Replace any bent hinges. Bent hinges can cause the rollers to bind. For best results, remove the hinges while the door is in the "up" position. Keep the door in position by placing c-clamps underneath the bottom roller. Then, support the door with 2 by 4s before removing the bolts on the hinge. If you don't support the door, it could bend or break.

  • Replace any rollers that are worn out. To replace the rollers, you need to first remove the hinge. See Step 4 for tips.

  • Tighten any loose screws, bolts and nuts on all hardware. This includes hinges, brackets and plates.

  • Lubricate the tracks and rollers with penetrating oil or spray. For the tracks, lubricant spray or powdered graphite works best. For the rollers, use household oil or silicone spray.

  • Using a level, check that each track is plumb. If a track is not plumb, loosen the bolts on the mounting brackets and tap lightly with a wood block and hammer. Once the track is plumb, tighten the bolts. Note: Step 7 can also be used to fix this issue.

  • Check that the two tracks are at the same height. If they are not, you may need to adjust the placement of the mounting brackets if the door binds when opening or closing. The mounting brackets is the metal that attaches the tracks of the garage door to the house. You may need to place a shim behind one or more of the brackets to fix. Note: Step 6 can also be used to fix this issue.
