Preventative Maintenance for Aluminium Roller Shutter Doors

​

​

Why Preventative Maintenance Is Important

Regular preventative maintenance helps to:

  • Extend the lifespan of the roller shutter and motor

  • Reduce the risk of breakdowns and costly repairs

  • Maintain smooth, quiet operation

  • Prevent corrosion and cosmetic damage

  • Ensure safety systems continue to function correctly

In coastal or dusty environments, maintenance becomes even more important. (Salt air and fine dust are very persistent little troublemakers.)

​

Cleaning Aluminium Roller Shutter Doors

Recommended Cleaning Frequency

  • Standard environment: Every 3–6 months

  • Coastal / dusty / industrial areas: Every 1–3 months

Regular cleaning prevents dirt, salt, and debris from building up in the guides and slats — the number one cause of noisy or stiff operation.

​

Step-by-Step Cleaning Process

1. Visual Inspection (Before Cleaning)

Before touching anything:

  • Check for dents, misaligned slats, or unusual gaps

  • Look for excessive dirt buildup in the side guides

  • Listen for scraping or grinding noises during operation

If something looks very wrong, stop and call a professional. Roller shutters are not the place for DIY heroics.

​

2. Cleaning the Curtain (Slats)

  • Fully close the shutter

  • Use warm water with a mild detergent

  • Clean using a soft cloth or sponge

  • Work from top to bottom

⚠️ Avoid:

  • Abrasive pads

  • Solvents

  • Pressure washers (your shutter doesn’t need a spa day at 150 bar)

  • ​

3. Cleaning the Side Guides

  • Brush out loose debris using a soft brush

  • Wipe guides with a damp cloth

  • Ensure drainage holes are clear

Clean guides = smooth travel = happier motor.

​

4. Rinse & Dry

  • Rinse with clean water

  • Allow the shutter to air dry fully before operating

  • ​

Lubrication (What Not to Do)​

  • Do NOT lubricate the guides with oil or grease

  • Oil attracts dust, which quickly turns into grinding paste

If lubrication is required, it should only be:

  • A dry silicone-based spray

  • Applied sparingly

  • Used only where recommended by a professional technician

  • ​

Recommended Professional Service Time Scale​

Even with regular cleaning, aluminium roller shutters should be professionally serviced to ensure safe and reliable operation.

​

Motorised / Automated Roller Shutters

  • Service interval: Every 12 months

  • Heavy-use or commercial installations: Every 6–12 months

  • ​

What a Professional Service Includes

A full preventative maintenance service typically involves:

  • Checking curtain alignment and slat condition

  • Inspecting side guides and fixings

  • Testing motor operation and limits

  • Checking safety systems (obstacle detection, manual override)

  • Inspecting control systems and wiring

  • Adjusting tension and settings where required

  • Identifying early signs of wear before failure occurs

Think of it as an MOT for your roller shutter — less dramatic than a breakdown, much cheaper than a replacement.

​

Signs That Service Is Needed Sooner

Contact a professional if you notice:

  • Increased noise during operation

  • Jerky or uneven movement

  • Slats catching or jamming

  • Shutter stopping partway

  • Remote or switch response delays

Ignoring these signs rarely makes them go away. They just wait… and get more expensive.

​

Summary

TaskFrequency

Light cleaningEvery 1–6 months (environment dependent)

Visual inspectionDuring every clean

Professional service (manual)Every 12–18 months

Professional service (motorised)Every 6–12 months

​

Final Word

A clean, serviced aluminium roller shutter door will:

  • Operate more quietly

  • Last significantly longer

  • Cost less over its lifetime

And best of all — it won’t choose a rainy Monday morning to stop working.
