Colorbond steel roofing is popular in Australia for its durability, low upkeep, and variety of colours. Yet, over time, the roof materials can get dirty, covered in lichen, mould, and stains, which can affect how your roof looks. High pressure cleaning can restore your roof’s appearance, but it’s important to clean your roof safely to avoid damage.
A professional roofing company will know how to pressure wash a Colorbond roof safely, but if you decide to clean it yourself, follow the manufacturer’s advice to avoid voiding the roof warranty. Using too much pressure or getting too close can harm your roof or damage the roof over time.
Is Pressure Washing Safe for Colorbond Roofs?
Pressure washing can be a very effective way to clean a Colorbond® roof safely when done with care. Colorbond materials have durable acrylic finishes that can handle medium pressure, but improper use of high pressure or harsh methods can cause the roof to chalk, wear away the paint, or even lead to the destruction of your roof over time.
The importance of Colorbond roof cleaning lies in maintaining the integrity of the roof and keeping your roof in top condition. To keep the look of the roof fresh and protect your roof warranty, it’s critical to use the right roof treatment and cleaning process. Always keep the pressure washer wand at least 30cm from the roof surface and use gentle cleaning solutions specifically designed for Colorbond roofs. This ensures your roof is clean without causing damage.
Pressure Washing Techniques and Professional Roof Cleaning
To clean your Colorbond roof effectively and safely, use low to medium pressure settings, generally between 1500 and 2500 PSI, and fan spray tips that provide a gentle cleaning solution across the roof. Move the pressure washer slowly in side-to-side motions, covering the entire roof and paying special attention to valleys and ridges where dirt and mould tend to accumulate.
Following a roof cleaning schedule with regular cleaning, typically once a year, is key to keeping your roof clean and maintaining its integrity over time. Roof work is risky, so many homeowners opt to hire professional roof cleaning services. Professionals know the best methods of cleaning Colorbond roofs safely and use the correct chemical cleaning products and equipment to keep the roof intact and protect the paint finish.
Whether you choose to clean the roof yourself or hire experts, understanding the safe cleaning process and inspecting the roof afterwards ensures your Colorbond roof can last for decades without losing its look or structural strength.
Tools and Equipment for Pressure Cleaning a Roof
To pressure clean Colorbond roofs, make sure to use cleaning products and equipment that are safe for Colorbond specifically. Choose a pressure washer with no more than 2000 PSI, and use a wide fan spray tip for even cleaning.
Tools to use:
- Pressure washer (1500–2000 PSI)
- 15-degree spray wand
- Fan spray tips
- Telescoping pole for hard-to-reach areas
- Soft mop or non-abrasive cleaning pad
- Bucket and gentle cleaning agent for roofing

If you’re using a chemical cleaning product, make sure it’s safe for Colorbond® roof materials and hose the roof down thoroughly to rinse away residue. Avoid using anything too abrasive that could harm the roof.
Safety Tips for Pressure Cleaning a Roof
Roof and work safety go hand in hand. Here are important steps to follow when cleaning your whole roof:
- Wear boots with a good grip and a fall harness.
- Never walk on wet or soapy surfaces.
- Clean your Colorbond roof in small sections.
- Use slow, overlapping strokes.
- Keep the spray wand 30cm from the roof.

Cleaning safely to avoid slipping or damaging your roof is key to getting the job done well.
Inspecting and Maintaining Your Colorbond Roof
After you’ve pressure cleaned the roof, inspect your Colorbond roof for signs of wear like chalking, rust, or peeling paint. Spotting these early can help avoid costly roofing repairs later.
Make inspections part of your regular roof cleaning schedule, ideally twice a year. Keeping your Colorbond roof clean not only enhances curb appeal, but it also helps preserve the material and extend its life.
