What is a Colorbond downpipe & general FAQ?
A Colorbond downpipe is a rainwater pipe made from genuine COLORBOND® steel that carries water from the roof gutter down to the stormwater system or another drainage point. While many people associate COLORBOND® steel with roofing and fencing, it also offers a range of products for gutters, fascia and downpipes as part of a complete exterior drainage system.
What is the purpose of a downpipe?
The job of a downpipe is to direct rainwater away from the roofline and control where that water ends up. Without an effective downpipe system, water can overflow from gutters and end up around walls, footings, paving, and garden beds, increasing the risk of stormwater damage and erosion. That is why gutters and downpipes are usually treated as one connected system rather than separate products.
Is a downpipe part of guttering?
A downpipe is not the gutter itself, but it is part of the home’s guttering or roof drainage system. Gutters collect the rainwater running off the roof, while downpipes move that water safely down away from the building.
What are Colorbond downpipes made of?
Genuine COLORBOND® steel downpipes are made from prepainted steel produced by BlueScope. They utilize a layered system that includes a steel base, metallic coating, conversion layer, corrosion-inhibiting primer, and a baked-on exterior paint finish designed for outdoor durability. The product is also made to relevant Australian Standards.
How long do Colorbond downpipes last?
The lifespan of a Colorbond downpipe depends on where it is installed, how well it is maintained, and whether the right product has been selected for the environment. Their downpipes are backed by a warranty of up to 20 years, subject to application and eligibility criteria. In real terms, that means a properly installed downpipe can last for many years, but harsher coastal or industrial environments may require more suitable grades such as COLORBOND® Ultra steel or other specialised options.
How much does it cost to replace gutters and downpipes in Australia?
The cost of replacing gutters and downpipes in Australia varies depending on the size of the home, the number of storeys, accessibility, profile choice, and whether old materials need to be removed first. As a general guide, gutter replacement roughly costs between $55 to $95 per metre and downpipe replacement at around $180 to $420 each, with total project costs increasing where access is difficult or the job includes extra roof plumbing work.
Conclusion
One of the biggest advantages of Colorbond downpipes is that they can be matched with the roof, gutter, fascia, garage door, or wall colours for a more consistent finish. They are also lightweight, durable, and designed for Australian conditions, which is why they remain a popular choice for both new builds and renovation projects. If you are choosing new gutters and downpipes, it makes sense to think about performance, colour coordination, environment, and long-term durability together, so the whole drainage system works well and looks right.
