Colorbond corrugated sheets are pre-painted steel roofing sheets rolled into a wave profile, and they suit most Australian homes, sheds and extensions. Pricing depends on thickness, colour, sheet length and how hard the roof is to reach, so you should expect a per-metre rate rather than a flat figure (indicative — get itemised quotes).
Below you’ll find how the profile works, how Colorbond roofing price per metre is built up, the compare-and-choose points and the install rules. Our custom orb corrugated guide covers the most common profile in more depth.
Key points
- A Colorbond corrugated roof is light, durable and fast to install, which keeps labour lower than heavier roofing types.
- The price of Colorbond roofing is built from sheet, flashings, insulation, fixings, labour and access, not the sheet alone.
- Match the profile, thickness and colour to your wind region, coastal exposure and the look of the house.
- Roof work is high-risk, so book a licensed roofer rather than walking on sheeting or lifting sheets yourself.
What are Colorbond corrugated sheets?
Corrugated sheets are rolled with a repeating wave that adds stiffness, so thin steel can span between purlins without bending.
| Term | What it means | Why it matters |
|---|---|---|
| Colorbond steel | Pre-painted steel from BlueScope with a baked-on colour finish | The factory finish is why Colorbond needs no repaint when it is washed and cared for |
| Corrugated profile | Repeating wave across the sheet, as in custom orb | It sets the look and affects how many sheets you need for the roof |
| Cover width | The width a sheet covers once the side laps are allowed for | Cover width, not sheet width, drives your quantity; see our Colorbond sheet width guide |
| Base metal thickness | The thickness of the steel before painting | Thicker steel resists denting and handles foot traffic better |
| Purlins and battens | Framing that supports the sheets | Fixing spacing is set by the manufacturer for each profile and wind region |
Colorbond corrugated roof profiles compared
The wave is the classic look, but other profiles share the same steel. This table compares the common choices.
| Profile | Look | Best for |
|---|---|---|
| Custom orb corrugated | Traditional round wave | Cottages, Federation homes, sheds and renovations; see our custom orb guide |
| Trimdek | Flat pans with raised ribs | Modern homes, low pitches and long runs; see our Trimdek guide |
| Standard corrugated | Shallower wave | Garages, carports and fencing |
| Insulated panels | Flat or ribbed sheet with foam core | Patios and additions that need heat control; see our insulated roof panels guide |
| Zincalume corrugated | Unpainted silver steel | Sheds and budget roofs; see Zincalume vs Colorbond |

Price of Colorbond roofing: what you are paying for
The price of Colorbond roofing is not one number, so ask for each line item separately.
| Item | What drives the price | Typical range |
|---|---|---|
| Sheeting only | Thickness, colour, profile and length | Mid cost per square metre (indicative — get itemised quotes) |
| Flashings, ridge and barge capping | Girth, length and number of bends | Quoted per lineal metre (indicative — get itemised quotes) |
| Battens, sarking and insulation | Type, thickness and roof area | Varies widely (indicative — get itemised quotes) |
| Labour to install | Pitch, storeys and access | Often the largest share (indicative — get itemised quotes) |
| Tear-off and disposal | Old roof type and quantity | Adds to the quote (indicative — get itemised quotes) |
| Scaffold and edge protection | Height and roof shape | Required on many jobs (indicative — get itemised quotes) |
Colorbond roofing price per metre and cost drivers
When you compare the Colorbond roofing price per metre between quotes, check that each includes the same scope.
- Supply only versus installed: a low supply rate looks cheap until you add flashings, fixings, labour and delivery, so compare installed totals.
- Roof shape: hips, valleys and dormers add cutting time and flashing, and a simple gable costs less per square metre than a cut-up roof.
- Pitch and height: steeper roofs and second storeys need safety systems that add cost to every quote.
- Colour and thickness: some colours and heavier gauges cost more, so ask for alternatives if you are working to a budget.
- Insulation and sarking: adding these during a reroof is much cheaper than retrofitting them later.
- Council and heritage: some Sydney areas control roof colours and profiles, so check before you order materials.
Colorbond corrugated roof: pros and cons
| Pros | Cons |
|---|---|
| Light weight puts little load on the roof frame | Rain noise on bare sheets without insulation or sarking |
| Wide range of colours, including heat-reflective lighter shades | Cut edges and scratches need care, particularly near the coast |
| Quick installation reduces labour time | Can dent under heavy hail or foot traffic |
| Low maintenance when washed regularly | Needs correct flashings and sealing at every penetration |
| Suits reroofs over existing battens when the frame is sound | Condensation can form under the sheets without sarking |
Installing a Colorbond corrugated roof safely
- Book a licensed roofer for any work at height, since roof sheeting is slippery and unsafe to walk on without edge protection.
- Check the existing roof for asbestos before any tear-off, because older fibre-cement sheets and eaves can contain it and must not be cut or scrubbed.
- Confirm your wind region and exposure so the sheet thickness, fixing pattern and purlin spacing match the manufacturer’s data for your site.
- Lay sheets against the prevailing weather so the side laps face away from the wind and rain.
- Use the manufacturer’s fixings and flashings in the right material, because mismatched metals corrode and may void the warranty.
- Walk only on the pans or over supports and never cut near a loaded edge, and clear swarf from the roof the same day so it does not rust and stain.
Common Colorbond corrugated sheets mistakes to avoid
- Comparing quotes without the same scope: one price may exclude flashings, scaffold or disposal and look cheaper than it is.
- Ignoring coastal exposure: salt spray attacks cut edges and underside surfaces, so wash the roof and choose the right grade near the sea.
- Using the wrong fixings: screws in the wrong material rust and leave streaks down your new sheets within a couple of seasons.
- Skipping insulation and sarking: a bare metal roof is loud in rain and can drip with condensation.
- Cutting with an angle grinder: hot swarf and abrasive discs damage the coating, so use nibblers or shears instead.
- Letting leaves sit on the roof: debris holds moisture, so keep valleys and gutters clean to protect the coating.
Colorbond corrugated sheets FAQs
How much does a Colorbond corrugated roof cost per metre?
Costs depend on thickness, colour, profile, roof shape and access, so a single rate rarely applies. Sheet-only pricing is far lower than an installed rate with flashings and labour. Ask for itemised quotes that show each cost line so you can compare properly.
What is the price of Colorbond roofing for a typical house?
The price of Colorbond roofing varies with roof size, pitch and extras such as insulation, gutters and scaffold. A simple gable costs less per square metre than a complex roof. Use an on-site measure and a written quote for a reliable total.
Is a Colorbond corrugated roof good for Sydney?
Yes. It is light, durable and available in lighter colours that reflect more heat. Near the coast, choose the right grade and wash the roof regularly to remove salt. Always confirm the profile suits your wind region with your roofer.
Can I install Colorbond corrugated sheets myself?
Not safely for most homes. Roof work involves falls, fragile or slippery sheeting and often asbestos on older roofs. A licensed roofer handles fixing, flashings and sealing correctly, and gives you a workmanship warranty that DIY work cannot.
