Colorbond® is one of the most popular roofing options in Australia thanks to its strength, low maintenance, and modern design. But when planning a roof replacement, the main consideration is cost. Knowing the price per m² installed helps homeowners set a realistic budget and compare quotes fairly.
In this article, we break down the typical cost of installing a Colorbond® roof, from material prices to labour rates, along with the factors that influence the final figure.
What Is the Typical Installed Cost per m²?
When budgeting for a Colorbond® roof, most contractors will quote based on the cost per square metre installed, which includes both the materials and the labour.
For most homes, the mid-tier range sits between $44 and $55 per m². This range is common across many Australian roofing companies and reflects the average rate for standard installations.
A broader full range of $53 to $97 per m² installed is also frequently reported. This accounts for variations in roof complexity, site access, and the grade of Colorbond® chosen. For example, standard corrugated sheets will cost less to install than Ultra-grade products designed for coastal or high-humidity areas.
In some cases, government data and industry-wide cost guides place the upper end of Colorbond® installation at around $120 per m². This higher figure is usually linked to challenging installations, multi-storey properties, or projects that include extras like new insulation, sarking, or guttering.
By understanding these ranges, homeowners can better compare quotes and avoid confusion when assessing whether a contractor’s price falls within normal industry standards.
Average Cost of Colorbond® Sheets per m²
Colorbond® roofing sheets come in different profiles and grades, and the cost per m² depends on the type selected. Here’s a comparison of common options:
| Sheet Type | Typical Cost per m² | Best Use Case |
| Corrugated | $13 – $18 | Affordable choice for standard residential roofs |
| Powder-coated | ~$22 | Homes needing added colour options and improved finish |
| Double-sided | ~$24 | Patios, carports, or projects where the underside is visible |
| Colorbond® Ultra | $36 – $38 | Coastal or high-humidity regions needing corrosion resistance |
| Specialty profiles (e.g., standing seam, custom orb) | $40 – $60+ | Premium architectural designs or modern finishes |
| Broader premium range | $20 – $200 | High-end or customised profiles with thicker gauges and specialty coatings |
These figures cover sheet-only costs. Once labour, old roof removal, and extras like insulation are added, the installed price per m² will be much higher.
Corrugated sheets are the cheapest option, but in coastal or high-rainfall areas, paying more for Colorbond® Ultra is often necessary to prevent corrosion. While the upfront cost is higher, it usually saves money on maintenance and repairs long term.
A standard Colorbond® roof can last 40–50 years, with premium grades offering even greater durability in harsh conditions. Contractor quotes vary because one may include basic sheets while another prices in Ultra-grade steel. Knowing the difference helps you compare quotes more accurately.
Example Total Costs for Different Home Sizes
The total cost of a Colorbond® roof depends largely on the overall size of the home. Below are average installed price ranges based on roof area:
| Roof Size | Typical Price Range (Installed) |
| 100–150 m² (Small) | $5,300 – $14,550 |
| 150–200 m² (Medium) | $7,950 – $19,400 |
| 200–300 m² (Large) | $10,600 – $29,100 |
| 300–400 m² (XL) | $15,900 – $38,800 |
Some roofing companies present costs in rounded figures. A small home roof replacement often falls between $15,000 and $25,000, while an extra-large roof can range from $50,000 to $60,000 or more.
These variations reflect factors such as labour rates, roof design, site access, and whether premium Colorbond® grades are included. This is why it’s important to request multiple itemised quotes to clearly see what each contractor has included in their price.
Factors That Drive the Installed Price
Several factors can push the final price up or down, including labour rates, roof size, and the type of material grade you select. These same factors also influence the total cost to replace roof with Colorbond®, which is why quotes can vary so widely between homes.
Here’s what makes the biggest difference:
Labour Rates
Most installers charge $40–60 per m² or $50–80 per hour. A simple roof is quicker and cheaper, while a steep or complex roof takes longer and requires extra safety gear, adding to labour costs.
Regional Differences
Labour is generally cheaper in Queensland ($40–45 per m²) compared to New South Wales ($55–60 per m²). Costs vary by state due to demand and cost of living.
Roof Design and Access
More gables, skylights, or valleys mean more cutting and fitting, which increases installation time. Homes with poor truck or crane access may also need scaffolding, which adds to the price.
Removal and Disposal
Taking off an old tile roof is more labour-intensive than removing metal. If asbestos is present, licensed removal and special disposal fees can increase costs significantly.
Project Type and Grade
A new build is usually cheaper than replacing an existing roof, since there’s no removal work involved. Choosing premium products like Colorbond® Ultra will raise the price, but they provide longer protection in coastal or high-humidity areas.
Smart Tips to Reduce Roofing Costs
Replacing a roof with Colorbond® is a big investment, but there are simple ways to manage the budget and avoid paying more than you should. Here are five proven strategies:
- Use a mid-tier estimate. Work with $55–70 per m² as a realistic benchmark for installed costs. This keeps expectations grounded without overestimating or underestimating your budget.
- Request itemised quotes. Ask contractors to break down the price of materials, labour, and removal. This transparency makes it easier to compare quotes and spot hidden charges.
- Get multiple quotes. Always compare at least three roofing companies. Prices can vary by thousands, and seeing several quotes helps you understand what’s fair for your roof size and design.
- Match the grade to your needs. Standard Colorbond® is enough for most inland homes. Premium options like Colorbond® Ultra should be reserved for coastal or high-humidity areas where extra protection is necessary.
- Plan your timing. Roofing demand is highest in summer and after storms. Scheduling your project during quieter months can mean faster service and, in some cases, better pricing.
