Roller doors are designed to last, but like any moving part, they experience wear and tear over time. If you’ve noticed your roller door making strange noises, moving unevenly, or refusing to open properly, it may be showing signs of age. If you own a B&D roller door, many of the original parts and service solutions are available through our Sydney team. The same applies if you have a Merlin garage door or a Steel-line garage door, our team carries genuine parts for both brands across Sydney.

In this article, we’ll look at common problems that affect older roller doors and what can be done to fix them.

Noisy Operation

Grinding, squeaking, or rattling sounds usually mean components need lubrication or have become worn out. Older roller doors often suffer from:

  • Dry or rusted tracks
  • Worn bearings in the roller drum
  • Loose fittings or panels

Applying a silicone-based lubricant and tightening any visible screws may help, but persistent noise often means a technician is needed.

Misalignment or Sticking

Roller doors should move smoothly. If yours feels jerky, sticks halfway, or refuses to open fully, it could be:

  • Misaligned tracks
  • Bent guide rails
  • Obstructions or debris in the path

In some cases, adjusting the tension or realigning the drum can resolve the issue.

Deteriorated Seals

Weather seals on older roller doors can become brittle, cracked, or completely fall off. This allows water, dust, and insects into your garage, and can also reduce insulation.

Replacing the bottom seal is a quick way to improve energy efficiency and protection.

Book professional servicing for roller doors

Motor or Opener Failure

Automated roller doors rely on electric motors that eventually fail. You might notice:

  • Delayed response to remote commands
  • Unusual humming or buzzing
  • Motor overheating

Depending on the age and brand, repairing or replacing the motor is often more cost effective than replacing the entire door.

FAQ: Roller Door Repairs & Maintenance

Why is my roller door making a grinding noise when opening?

Grinding typically indicates dry or worn rollers, debris in the guide tracks, or worn bearings in the coil mechanism. Applying a silicone-based lubricant to the rollers, hinges, and coil spring often resolves minor grinding. If the noise persists after lubrication, the rollers or bearings are likely worn and need professional replacement.

Can I adjust a misaligned roller door myself?

Minor guide rail adjustments can sometimes be done by a homeowner by loosening and repositioning the mounting brackets. However, spring tension adjustments and cable realignment must be done by a licensed technician. Roller door components operate under significant mechanical tension and incorrect handling can cause serious injury.

How do I know if my old roller door needs replacement rather than repair?

Replacement is likely more cost-effective when: the door is over 20 years old, repair costs exceed 50% of a new door’s price, parts are no longer available, or there have been multiple breakdowns within a 12-month period. A technician can provide an honest on-site repair vs replace assessment.

How often should the weather seals on a roller door be replaced?

Rubber bottom seals typically last 3–7 years depending on UV exposure and use frequency. Replace them when you notice visible cracking, gaps letting in light or water under the closed door, or the seal dragging excessively. Side brush seals and top weather strips should also be inspected annually.

Is it worth repairing a roller door that is more than 15 years old?

It depends on the fault. Replacing seals, lubricating components, or repairing an opener motor is often worthwhile on older doors if the curtain is structurally sound. However, if the curtain is bent, the coil spring is worn out, or the door has multiple simultaneous issues, a new door is usually more economical.
