What is the best type of guttering for Australian homes?
The best type of guttering for Australian homes depends on your location, roof design, and environmental conditions. In most cases, Colorbond® steel is considered one of the top choices due to its durability, corrosion resistance, and suitability for harsh weather. In coastal areas, materials that resist salt corrosion—like pre-painted steel or aluminium—are ideal.

Box gutters are commonly used in modern architectural designs, while quad or half-round gutters are often seen on traditional homes. It’s important to also consider the size and shape of the gutter, as this impacts how much water it can handle during heavy rainfall. Consulting with a supplier or trade professional can help determine the right fit for your home.
How much rainwater can I collect from my roof?
The amount of rainwater you can collect depends on the size of your roof and the average rainfall in your area. As a general rule, for every 1mm of rainfall, you can collect about 1 litre of water per square metre of roof area. For example, a 100m² roof in an area that receives 1,000mm of rain annually could theoretically collect up to 100,000 litres of water per year.

However, actual collection may be lower due to system losses from evaporation, leaks, or overflow. Using appropriate guttering, downpipes, and a properly installed rainwater tank system can maximise collection and help manage water sustainably.
What’s the difference between downpipes and gutters?
Gutters and downpipes are both essential components of a rainwater drainage system, but they serve different functions. Gutters are the horizontal channels installed along the edge of your roof to catch and direct rainwater as it runs off.

Downpipes are the vertical pipes connected to gutters that carry the collected water down to the ground, where it can be directed to a stormwater drain, rainwater tank, or garden.

Without properly sized and installed downpipes, gutters can overflow during heavy rain, causing water damage to your roof, walls, and foundations. Together, these two components protect your property by managing water flow effectively.
