Frequently Asked Questions

What is a box gutter?

A box gutter is typically “boxed” into the centre or edge of the roof and is designed to collect and direct water through the downpipe system, keeping your building watertight and structurally protected.

What fall should I have on a COLORBOND® box gutter?

A minimum fall of 1:200 is recommended to ensure efficient drainage and prevent overflow or pooling issues.

Where is the colour on a COLORBOND® box gutter?

The COLORBOND® finish is folded on the inside of the gutter. This maintains the clean visual roofline and protects the gutter's interior from corrosion.
