Colorbond Roof Cleaning

Pressure Washing

Pressure washing removes heavy grease, advanced rust, acid rain stains, food stains, water stains and tough dirt. Use moderate water pressure with a pressure washer, fan spray tips and a 15-degree spray wand.

Soft Washing

Soft washing is for sensitive roof materials, using eco-friendly chemical solutions without harsh chemicals to remove moss spores, black algae growths and dead growths without damaging the durable acrylic paint and protective coating.

Preparation Steps

• Safety Precautions: Wear proper safety gear, eye protection, gloves, harnesses and sturdy shoes.
• Clearing Debris: Use soft brush, squeegee mop or telescoping pole to clear the roof surface of loose debris.
• Weather Conditions: Clean on mild days, don’t clean on wet surfaces to avoid accidents.

Cleaning Process

1. Apply Roof Cleaning Solution: Apply eco-friendly roof cleaning solution to the entire steel roof, including garage roofs, pergola roofs, or roofs over outdoor tiles.
2. Soaking Time: Let the solution sit for 5-10 minutes to loosen dirt, grime and organic matter.
3. Gentle Scrubbing: Tackle stubborn stains and heavy debris with a soft brush or pressure washer on low pressure.
4. Thorough Rinsing: Rinse with moderate water pressure and fresh water, make sure all dirty water and residue are removed.

Post-Cleaning Care
