1. Girth
Girth is the width of flat sheet the flashing is folded from — add up every leg of the profile. A wider girth uses more steel, so it costs more per metre. Girths are priced in size steps, and a girth between steps rounds up to the next one.
How much does flashing cost?
Custom flashing is priced per lineal metre. Four things decide the rate — here's how it works, so you know what to expect before you ask.
What sets the price per metre
2. Number of folds
Every bend is machine time, so more folds cost a little more per metre. A squash (crush) fold counts as two folds.
3. Material and finish
Plain Zincalume® is the most economical. Standard Colorbond® costs a little more, and the Colorbond® Matt finish a little more again. Same price for every colour within a finish.
4. Tapers
A tapered flashing — a different girth at each end, for a roof that isn't square — carries a small extra charge per metre.
Working out your total
Your total is simply the rate per metre multiplied by the total metres you order. Every length is folded to the size you ask for, so you only pay for what you need.
- A narrow, two-fold apron flashing costs less per metre than a wide, four-fold barge capping.
- The same profile in Zincalume® costs less than in Colorbond®.
- A one-off repair piece is priced the same way as a full project order.

Flashing price questions
Is Colorbond flashing more expensive than Zincalume?
Yes, slightly. Zincalume® is the most economical finish; Colorbond® costs a little more per metre, and Matt a little more again.
Do different Colorbond colours cost more?
No. Every colour in the standard Colorbond® range is the same price. See the colour range.
Is a custom flashing dearer than a standard one?
Not because it's custom. The price comes from girth, folds and material, so a custom profile costs the same as a standard one of the same size.
What is girth?
The total width of flat sheet before folding — the sum of every leg of the profile, in millimetres. It's the main thing that sets the price.
