Quick Summary

Regular Cleaning

Wash roof boxes with car shampoo and water after each trip to prevent dirt buildup and corrosion.

Proper Storage

Store in dry location with lid slightly open for air circulation when not in use.

Seal Maintenance

Check and lubricate rubber seals annually to maintain weatherproofing and prevent leaks.

Winter Preparation

Clean thoroughly and dry completely before long-term storage to avoid mould and damage.

Proper maintenance extends your roof box lifespan from 5 years to 10-15 years. This guide covers everything from routine cleaning to winter storage and common problem fixes.

Regular Cleaning & Care

After Each Trip: Wipe down exterior with mild soap and water. Check all clamps and locks for debris. Remove any insects or tree sap promptly as they can damage the finish.

Monthly (if installed): Inspect seals and gaskets for wear. Lubricate hinges and locks with silicone spray. Check for cracks or stress marks around mounting points.

Proper Storage

Indoor Storage (Ideal): Store in garage on its side on padded surface. Keep away from direct sunlight and heat sources. Slightly open the lid to allow air circulation and prevent moisture buildup.

Outdoor Storage: If you must store outside, use a weatherproof cover. Elevate off ground on wooden boards. Position to avoid water pooling on lid.

Common Problems & Solutions

Whistling Noise: Usually caused by improper positioning or loose clamps. Reposition box slightly forward and retighten all clamps. Consider adding wind deflector.

Difficult to Open/Close: Lubricate hinges and locking mechanism with silicone spray. Check for warping from improper storage. Replace worn gaskets if needed.

Water Leaks: Inspect door seals and replace if damaged. Ensure lid closes completely flush. Check drain holes aren’t blocked.

Cracks or Damage: Small cracks can be repaired with plastic weld or epoxy. Large cracks or structural damage require professional assessment or replacement.

Seasonal Maintenance

Before Winter: Apply protective wax coating. Check all seals are intact. Lubricate locks (they can freeze). Store indoors if not using through winter.

Spring Prep: Thorough cleaning after winter storage. Inspect for any damage from temperature changes. Test all clamps and locks before first use.

Regular maintenance takes just 30 minutes quarterly but can double your roof box’s lifespan. Need professional inspection? Our Birmingham service center offers free safety checks.
