      Colorbond roofing fades primarily due to prolonged exposure to Australia’s harsh UV radiation, which breaks down the pigments in the paint. Other factors that contribute to fading include extreme weather conditions, pollution, chemical exposure (especially in coastal areas), and poor maintenance.

      Colorbond steel has become a household name in the Australian building industry. Whether you’re roofing your home or fencing your backyard, it’s hard to find someone who isn’t familiar with this popular material. 

      Known for its durability, strength, and stylish look, Colorbond is the go-to for many Aussies.

      But like everything under our intense sun, Colorbond can fade over time. 

      While it’s built to last, understanding why it fades and what you can do about it is key to keeping your home looking fresh for years to come.

      The Main Causes of Colorbond Fading

      So, what makes your once shiny Colorbond lose its color? Let’s break it down. 

      • Exposure to UV Radiation

      This is the big one. Australia’s harsh sunlight is notorious for its ability to fade just about anything, and Colorbond is no exception. 

      The UV rays from the sun break down the pigments in the paint, leading to a gradual loss of color intensity.

      • Weathering and Atmospheric Conditions

      Between the sun, rain, wind, and even hail, the weather in Australia can be brutal. Over time, these elements wear down the surface of Colorbond, especially in areas that see extreme conditions.

      • Pollution and Chemical Exposure 

      Colorbond roofing in urban areas can experience more rapid fading due to pollution in the air, which can settle on the surface and react with the paint. Chemicals like salt in coastal areas or industrial fumes can speed up the fading process as well. 

      • Poor Maintenance

      Like your car or your barbecue, Colorbond needs a little TLC. If you neglect to clean and maintain it, dirt, grime, and other pollutants can accumulate, leading to accelerated fading.

      • Age and Wear and Tear

      They say nothing lasts forever. As your Colorbond roof gets older, natural wear and tear will take its toll. However, with proper care, it can still serve you well for decades.

      Some Factors Affecting Colorbond Fading

      It is not all Colorbond products that fade equally. These are some factors that can influence how quickly your Colorbond loses its sheen: 

      • Color and Finish 

      Some colors are more susceptible to fading than others. Darker colorbond shades typically absorb more sunlight and can fade faster than lighter ones.

      • Orientation and Exposure 

      How your Colorbond is positioned plays a big role. Consequently, surfaces that face direct sunlight for most of the day will fade faster than those in the shade.

      • Coastal vs. Inland 

      Living by the coast can be great, but the salty air isn’t so kind to your Colorbond. Colorbond roofs located in inland areas generally experience slower fading when compared with coastal locations.

      • Quality of Installation and Material 

      Poorly installed Colorbond roofing or cheaper versions that don’t have the same protective coatings can fade more quickly. Which is why it’s better to choose quality over cheaper materials when purchasing colorbond roofing. 

      Common Signs of Colorbond Fading

      Is your Colorbond starting to look a bit worn in appearance? Or maybe you just purchased the home and aren’t sure what the true color of the roof is. 

      Here’s how to tell if it’s fading. 

      • Discoloration

      One of the first signs of fading is uneven or patchy colors. The once uniform shade may start to look washed out in certain areas.

      • Chalking

      Chalking refers to when the surface of colorbond roofing begins to develop a powdery residue. It is a sure sign that the top coat of the paint is breaking down.

      • Rust and Corrosion 

      Before this, colorbond roofing would have gone through the process of chalking. It would have lost most of its sheen. 

      Fading can sometimes go hand-in-hand with rust, especially if the protective coating is damaged.

      • Loss of Gloss 

      A once-glossy finish can become dull and matte as the surface wears away. If this is difficult to tell by sight, simply find a way to touch the surface and you’ll feel the loss of sheen. 

      Prevention of fading and Maintenance

      Luckily, there are ways to slow down the fading process and keep your Colorbond looking fresh. Here’s how: 

      • Regular Cleaning 

      A little maintenance goes a long way. Clean your Colorbond surfaces with soapy water and a soft brush to remove dirt and pollutants that can cause fading. Using a soft brush helps to prevent abrasion of the top covering which gives colorbond its beautiful appearance. 

      • Protective Coatings

      Some Colorbond products come with additional protective coatings that help resist fading. But you can also apply your own UV-protective sealants to prolong its life. As they always say, the more the merrier. 

      • Avoid Harsh Chemicals 

      Stay away from abrasive cleaners or harsh chemicals. These can strip away the paint and cause premature fading. Also, using this kind of solution when washing leads to patches of sheen loss. This causes colorbond to look unsightly. 

      • Inspect for Damage 

      Regularly checking your Colorbond for any signs of damage, like scratches or rust helps to make it last too. Addressing these early signs of deterioration can prevent further deterioration.

      Repair and Replacement Options

      If your Colorbond is starting to look worse for wear, don’t panic—there are plenty of options for repair and replacement. If you have no idea what to do, reach out to us and we’ll help you with your colorbond roofing. For now, here some of the things you can do for yourself: 

      • Touch-Up Painting 

      You can paint colorbond roofing. Just be sure to match the color as closely as possible.

      • Panel Replacement

      If fading is widespread, you might want to consider replacing some panels. While doing this could potentially be more costly, it can give your home a fresh, updated look.

      • Upgrading

      If your Colorbond is older, you could consider upgrading to a newer, more fade-resistant materials that are designed to last longer in Australia’s harsh climate.

      Final Notes 

      Colorbond is a fantastic material, and with proper care, it can last for years. Fading is a natural process, especially in Australia’s extreme weather conditions, but with regular maintenance, cleaning, and inspections, you can slow down the effects and keep your Colorbond looking its best.
