Downpipes Central Coast

Q: What materials do you use for downpipes?

We install Colorbond® steel and Zincalume® downpipes , both of which are durable, low-maintenance, and available in a wide range of colours to match your gutters and roof.

Downpipe Installation Central Coast

A downpipe plays a vital role in your roof drainage system, transferring water from your gutters into your stormwater drain or water tank. Choosing the right size, shape, and material is important to ensure your roof drains efficiently—especially during heavy Central Coast rain.
When selecting downpipes, we consider:

How much water each downpipe will need to carry
The amount of leaf matter likely to enter the gutter system
The overall design of your gutters and roofline

If you have a gutter guard system installed, the risk of leaf matter entering the gutters is removed—allowing us to focus purely on water flow capacity without worrying about blockages.

We install a range of durable downpipe options, including:

Colorbond® and Zincalume® steel for long-term performance and colour matching
PVC downpipes, widely used with rainwater tank systems due to their smooth internal surface and corrosion resistance

Whether you’re replacing damaged downpipes, upgrading your guttering, or installing a new roof, AWS Roofing ensures your downpipes are correctly sized, positioned, and installed for maximum efficiency.

Downpipe Sizes and Shapes

Aesthetic elements can also be considered in terms of both shape and colour, with either rectangular or round shapes fitting in with the style of each individual home. Downpipes also come in a range of colours, which can be fitted either matching the gutter system, or in a different colour, possibly matching the wall colour.

With a wide variety of sizes, colours, materials and functionality levels to choose from, AWS Roofing can recommend the right solutions for your home.
