How to Repair a Roller Garage Door (and What It Might Cost)
Roller garage doors are one of the most convenient and space-saving options for homeowners — smooth, secure, and ideal for automation. But like any mechanical system, they can sometimes develop issues with motors, locking straps, or control boards that stop them working properly.
So, how do you repair a roller door? And how much does it cost? Let’s break it down.
🔧 How to Repair a Roller Garage Door
The process depends entirely on the fault. Common issues include:
Door not opening or closing properly – often caused by worn locking straps or damaged slats.
Motor not responding – could be due to a failed motor unit, faulty wiring, or a control board issue.
Door jammed or uneven – sometimes caused by misaligned tracks or obstructions in the barrel.
Remote not working – may need reprogramming or a replacement receiver.
A professional technician will always start by carrying out a full diagnostic check, inspecting:
✅ The motor and control unit
✅ Safety edge and photocells
✅ Locking straps and barrel alignment
✅ Remote system and wiring
Only after this inspection can the correct repair be determined — and that’s why the cost can vary greatly.
