Roller Door Repairs

Roller doors fail differently from sectional doors. Where a sectional has springs, panels, hinges, rollers, tracks, and cables to go wrong, a roller has a coil, side guides, springs, a motor, and that’s it. Fewer moving parts means fewer failure modes — but when they do fail, the failure tends to be straightforward to diagnose.

Common Adelaide roller-door faults

Door binds in the side guides

Dirt, salt corrosion (coastal suburbs — Henley Beach, Glenelg, Aldinga), or guide-rail distortion from a vehicle hit. Fix: clean and lubricate, or straighten/replace the guide. $180-$320.

Door won’t fully close (or open)

Limit switch out of adjustment, or a worn drive sprocket on the motor. Fix: limit reset $90-$140, sprocket replacement $220-$340.

Door rattles loudly when operating

Coil bearing wear, loose end-bracket bolts, or a sagging spring. Fix: bearing replacement $240-$360, spring replacement $260-$420.

Bottom slat damaged

A reversing vehicle has crushed the bottom slat. Fix: bottom slat replacement $180-$340.

Door sags in the middle

Spring fatigue. The door has been in service 12-15+ years and the spring’s lost its tension. Fix: spring replacement $260-$420; full door replacement starts to look attractive at the 18-20 year mark.

Manual lock seized

Common on doors that have been left motorised for years and the manual lock cylinder has corroded. Fix: lock service or replacement $80-$160.

Coastal Adelaide considerations

Roller doors in Henley Beach, Glenelg, Aldinga, and the southern coastal suburbs corrode faster than inland doors. Salt-laden onshore winds attack the steel coil, the springs, and the motor housings. Annual servicing — wash-down, lubrication, fastener tightening — extends life from ~12 years to ~18 years. Worth doing.

When repair is worse value than replacement

If your roller door is over 18 years old, has lost spring tension, has corrosion at the coil ends, AND has a tired motor, the cumulative repair cost ($800-$1,400) approaches the cost of a full new install ($1,400-$2,800). At that point a new door with new motor and a 5-year warranty often makes more sense.
