Colorbond steel is a popular roofing choice in Australia due to its durability and heat resistance. Like any roofing material, you need to regularly clean your Colorbond roof to keep it in optimal condition.

Colorbond is a special kind of steel, and many homeowners are unsure how to clean it. But cleaning colorbond roof materials doesn’t need to be difficult, luckily, the team at Fremantle Roofing Services is here to provide some tips on how to clean a Colorbond roof.

What Is Colorbond Steel?

Colorbond steel is a special kind of high-performance steel known for its durability and thermal properties. Colorbond steel consists of five distinct layers:

  •    High-grade steel base
  •    A layer of BlueScope’s Activate technology
  •    Pretreatment layer
  •    Polyester primer
  •    Speciality topcoat

BlueScope uses a patented process to produce Colorbond steel, which gives the metal an extremely high-tensile strength. Colorbond steel is not only tough but is also highly resistant to weathering and corrosion.

Colorbond is also thermally efficient and can regulate the temperature of your home during the winter or summer. Moreover, Colorbond has 22 distinct colour options to choose from. Overall, Colorbond is an excellent choice for the coastal climate of areas such as Perth.

Advantages of Colorbond Roof Steel As A Roofing Material

Colorbond steel has several advantages over traditional roofing materials, such as:


First off, Colorbond steel has extremely high tensile strength and is resistant to scratching and impacts. BlueScope’s unique molding process reinforces the steel, making it stronger than normal.


Colorbond steel also has excellent thermal regulation properties. A Colorbond roof can insulate your home during the winter and summer, saving you money on heating and cooling costs.

Corrosion Resistance

Additionally, Colorbond steel is resistant to rusting and chemical corrosion. A Colorbond steel roof can easily shrug off rain, dirt, and other substances relatively easily. Colorbond steel is also resistant to UV fading from the sun.

Cleaning Colorbond Roof Materials

Colorbond is high-quality steel, but it requires regular care and maintenance. Cleaning Colorbond roof steel is an integral part of maintaining the integrity of the colorbond roof. Failing to clean your roof or patio can result in problems down the road, so homeowners should learn how to clean their Colorbond roofs.

You can use several methods to clean Colorbond steel. Here are some of the most popular ones.

Pressure washer use on your Colorbond roof

Pressure washing is a quick and efficient method for cleaning a residential roof. You can use a high-pressure or medium-pressure washer to blast away dirt and debris and can rent or buy a pressure washer for cleaning, but you may need to modify the settings for Colorbond steel.

All things considered, pressure washing is a low-cost cleaning method, but it won’t be able to handle tougher messes.

Chemical Washing your Colorbond roof

Several companies produce chemical cleaning products that you can use to metal roofing panels. The most common chemical washing substances are chlorine and sodium-based products. These two chemicals can eat through tough grime without harming the underlying metal roof surfaces and are also relatively safe for your health.

Solvent Cleaning your Colorbond roof

You can also use solvents to clean Colorbond steel. Solvents are special chemicals that can remove stubborn build-up that pressure washing cannot. Solvents are the ideal cleaning solution for dirt, paint, rubber marks, and grease.

Solvents are a powerful cleaning method but require careful handling. Certain solvents can damage the topcoat and paint layers after prolonged exposure on metal roofs. Additionally, solvents can be harmful to your health, so make sure you wear proper hand, eye, and mouth protection.

What Is the Best Method for Cleaning a Colorbond Roof?

The best method for cleaning a Colorbond roof depends on what kind of debris you need to clean. For regular dirt and debris, a thorough power washing should be enough to clean the panels. However, tougher messes may require a chemical or solvent solution.

Can I Clean a Colorbond Roof on My Own?

Yes, you can clean a Colorbond roof on your own. However, it is often in your best interest to hire a professional. Professional roof cleaners understand the best methods to remove grime and have experience handling harsh chemicals.

How Often Should I Clean My Colorbond Roof?

We recommend that you perform a deep clean once every two to three years. However, you should have professionals inspect your roof at least once a year to catch any problems that cleaning cannot fix.

Tips for Colorbond Roof Cleaning

Here are some tips on how to Colorbond Roof Cleaning
