Garage Door Roller Replacement

Rollers wear slowly, so the change is easy to miss. Watch the door run through one full cycle and listen. A healthy door makes a steady hum from the opener and not much else. Worn rollers add grinding, clicking or a rumble that gets louder at the curve where the track turns from vertical to horizontal.

With the door closed, you can also look at the rollers from inside the garage without touching anything. Wheels should be round and smooth. Signs of wear include wheels that are cracked, chipped or worn into an oval, steel rollers with rust or loose bearings, and stems that are bent so the wheel sits at an angle in the track. A door that shakes as it moves is a strong sign too.

There isn't one right answer for every door. It depends on the door's weight, how often it cycles and how much noise matters to you. Here is how the common types compare:

• Basic plastic rollers: the low-end option on many builder-grade doors; they wear fastest and often have no bearings
• Steel rollers without bearings: tough but loud, and they wear the track faster
• Steel rollers with ball bearings: strong, a good fit for heavy doors and commercial use, but noisier than nylon
• Nylon rollers with sealed ball bearings: quiet and smooth, the upgrade most homeowners notice right away
• Number of bearings matters: more bearings generally means smoother, longer-lasting rollers

For most attached garages, especially ones under a bedroom or next to the kitchen, sealed-bearing nylon rollers are the upgrade we suggest most. They roll quietly, don't need much lubrication and don't rust. In a humid climate, that last point counts: bare steel rollers in a damp garage pick up surface rust, and rusty bearings get loud and stiff.

Steel still has its place. Heavy wood or oversized doors, and doors that cycle many times a day, can be a better match for a heavy-duty steel roller. We'll look at your door and tell you which makes sense. Roller choice also matters for commercial garage door repair, where doors cycle far more often than a home door.

Roller life depends on the roller quality, how often the door runs, the door's weight and the conditions in your garage. A low-grade unsealed roller in a busy, dusty garage can wear out much sooner than a sealed-bearing roller on a lightly used door. Humidity, salt and grit all shorten their life.

Rather than counting years, we go by condition. If rollers are loud, wobbly or visibly worn, they are due. A garage door maintenance visit includes a roller check, so you'll hear about wear before a roller breaks and the door jumps the track.

Some rollers are easy to reach, but not all of them. The bottom rollers on each side sit in the bottom brackets, which are connected to the lift cables and under spring tension. Removing those brackets without first releasing the springs can cause serious injury. That's the part of a roller job we never recommend doing yourself.

There's also the risk of pulling a door out of alignment while swapping rollers one at a time. If the job is done by a technician, we unload the springs where needed, replace all rollers together and check the track and hinges at the same time.

Rollers ride in hinges and brackets, and they run in the track. If one part is worn, the others often are too. A roller stem that wobbles may mean the hinge hole is worn oval. A roller that keeps chewing up may point to a track that is bent or out of plumb. Replacing rollers in a bad track just wears out the new ones faster.

When we replace rollers, we check hinges for cracks, tighten loose hardware, look the track over for kinks and lubricate where it's appropriate. If the door has already slipped out of the track, see our off-track garage door repair page.

Price depends mainly on the door and the rollers you choose, so we quote after seeing it. Factors include:

• Number of rollers (single doors and double doors use different counts)
• Roller type: nylon or steel, number of bearings, stem length
• Whether hinges or bottom brackets also need replacing
• Track condition and any alignment work
• Whether it's done alone or with a tune-up or other repair
