If you’re preparing to revamp your home, understanding the cost of a new roof is critical to ensure you’re financially prepared. Since it’s a major investment, knowing how much a new roof costs can prevent project delays and unnecessary expenses in the long run.Â
Based on our research, you’re likely to shell out $25 to $520 per square metre in Australia. However, the final cost still depends on several factors, from materials and labour to your home’s size and location. We’ll walk you through these important considerations to guide your decision.
New roofing cost breakdown by roofing type
Factors such as roofing material and design play a role in determining how much should a new roof cost, with choices like metal roofing or shingles and flat or pitched roofing.
Let's explore the different types of roofing systems available in Australia, including their characteristics, durability, maintenance needs, aesthetic appeal, and roofing cost per m2.
Note: We used 200 square metre as the standard roof size in our price tables to show how much you’d likely spend for an average-sized roof in Australia.
Metal roofing
Type of metal roofing |
Average cost per square metre |
Average cost for a 200-square-metre roof |
---|---|---|
Colorbond |
$45 to $100 |
$9,000 to $20,000 |
Corrugated steel |
$30 to $170 |
$6,000 to $34,000 |
Aluminium Zinc (Zincalume) |
$40 to $80 |
$8,000 to $16,000 |
Copper |
$180 to $400 |
$36,000 to $80,000 |
If you're looking for a sleek and durable roofing option, a metal roof might be the perfect fit. The average cost of a new metal roof is anywhere from $30 to $400 per square metre or $6,000 to $80,000 for a standard 200-square-metre roof. Materials like Colorbond steel are especially popular in Australian homes due to their ability to withstand harsh weather conditions.Â
Metal roofs are also lightweight, fire-resistant, and require minimal maintenance. Plus, with various styles and colours available, you don’t have to sacrifice aesthetics for strength. They’re also reasonably priced. A new steel roof costs around $30 to $170 per square metre.
Budgeting tip: Don’t forget about sarking, a reflective foil installed under a metal roof to improve insulation and protect against water and dust ingress. It’s typically priced at $4 to $10 per square metre, but one 60x135-metre roll costs $185 to $300.
Tiled roofing
Tiled roof material |
Average cost per square metre |
Average cost for a 200-square-metre roof |
---|---|---|
Concrete tiles |
$45 to $80 |
$9,000 to 16,000 |
Terracotta tiles |
$75 to 140 |
$15,000 to 28,000 |
Copper tiles |
$180 to 190 |
$36,000 to 38,000 |
Solar roofing tiles |
$250 to $350 |
$50,000 to 70,000 |
Slate tiles |
$250 to $520 |
$50,000 to 104,000 |
Tiled roofing is a popular choice for bushfire-prone areas since tiles are non-combustible. They're also durable and can last a lifetime if maintained properly. New roof tiles cost $45 to $520 per square metre. So, expect to pay $9,000 to $104,000 for a standard 200-square-metre roof.
Concrete tiles are affordable and widely used in residential homes. They provide good insulation and are available in various colours and styles. Terracotta tiles, made from natural clay, are known for their earthy tones and ability to withstand harsh weather conditions.
Copper tiles are a premium option that develops a patina over time. Solar tiles, on the other hand, generate electricity, besides protecting your home. The initial costs might be high, but you’ll enjoy long-term savings on energy bills with this type.
Meanwhile, slate tiles are high-end natural stone tiles that offer a timeless and sophisticated look. They’re incredibly durable and resistant to fire and weather. However, their weight requires strong structural support and professional installation by slate roofers.
Flat roofing
Flat roofing is commonly used for extensions, garages, verandah roofing, and patios Materials typically used include bitumen, fibreglass (glass-reinforced plastic or GRP), and rubber membranes. A new flat roof costs anywhere from $22,000 to $40,000 for a standard 200-square-metre roof. On average, flat roofs cost $110 to $200 per square metre.
Bitumen is cost-effective but may degrade over time. Fibreglass or GRP offers a seamless, waterproof finish that’s long-lasting and low-maintenance. Meanwhile, rubber membranes are durable and easy to install.Â
Asphalt roofing
Another common type of roofing is the asphalt shingle. It is a roof system made primarily out of asphalt components. A new shingled roof costs anywhere from $25 to $100 per square metre or $5,000 to $20,000 for a standard 200-square-metre roof.
Its lifespan can last up to 30 years with regular maintenance. While they might not have the same longevity as metal or slate options, they offer decent protection against elements and come in various shades for customisation as well.
What are the factors affecting roofing costs?
New roof costs aren’t just about the tiles or metal sheets you choose. There are several other factors that can influence the final price tag. From where you live to the size and complexity of your roof, here are what to consider before starting your roofing project.

Where you live in Australia can significantly impact your roofing costs. In bustling cities like Sydney and Melbourne, roofing projects tend to be pricier due to higher labour rates and material costs driven by elevated living expenses. For example, in Sydney, average roofing costs range from $150 to $210 per square metre.
On the flip side, cities like Adelaide offer more affordable options, with costs ranging from $100 to $160 per square metre. Brisbane and Perth also have lower labour costs, with typical roofing prices between $120 and $185 per square metre.Â
Climate conditions in your region can also affect costs. Coastal cities like Sydney and Brisbane require roof materials that can withstand harsh weather conditions such as salt corrosion, high humidity, and strong winds. This often means investing in more durable materials like Colorbond steel. Likewise, Melbourne and Perth may require additional insulation to handle temperature fluctuations.
Accessibility is another factor to consider. In densely populated urban areas, restricted access and tight spaces can increase labour costs because the job becomes more complex and time-consuming. Plus, each city has specific building codes and regulations.Â
Roof size and areaÂ
The size of your roof plays a huge role in determining the overall cost. A larger roof means you’ll need more materials and more labour, which naturally increases expenses. The cost of a new roof per square metre can vary based on the material you choose, so knowing your roof’s dimensions is needed to budget accurately.
But don’t forget, some fixed costs like scaffolding and permits remain the same regardless of size. So even if your roof is small, these expenses may seem costly when factored overall.Â
To get a clear estimate, measure your roof’s total area and consider the type of roof materials you plan to use. This will allow you to calculate the approximate cost per square metre and avoid any surprises down the line.
Roof slope and complexity
The steepness and design of your roof can significantly affect roof replacement costs as well. Steeper roofs are harder to work on and require extra safety measures and more labour time. Flat or gently sloped roofs are generally cheaper to install but might need special waterproofing materials that add to the expense.
Complex roof designs also drive up costs. Roofs with intricate layouts—like curved, butterfly, A-frame, and saltbox—need more materials and labour. Each additional feature, such as dormers, chimneys, or valleys, requires precise cuts and flashing to prevent leaks, which takes more time and skill.
For example, replacing a simple gable roof is less expensive than tackling a complex hip roof with multiple angles and features. So, if your roof has a steep pitch or complicated design elements, be prepared for higher expenses.
Additional costs
Additional cost factors |
Average costs |
---|---|
Sarking |
$4 to $10 per square metre |
Labour costs |
$6,000 to $22,000 |
When calculating the total price of your new roof, don’t overlook extra expenses that can add up. For instance, sarking, as mentioned above, costs about $4 to $10 per square metre. Labour costs are another factor. Depending on the size and complexity of your roof, the total new roof replacement costs, including labour, can range from $6,000 to $22,000.Â
Structural repairs might also be necessary. If there’s rotten timber that needs replacing, or if you’re switching to heavier materials like terracotta or slate, you may need to strengthen your roof’s structure. And don’t forget about ventilation systems. Installing a dry fixed roofing system can help reduce energy costs and prolong your roof’s lifespan.Â
Fascia and soffits are also part of the package. If you're considering installing gutter guards or need gutter repairs, that could add to the expense, too.
Urgency and seasonal demand
Timing is also everything when it comes to roofing costs. In Australia, autumn is often the ideal time for roofing work. The weather is stable, projects are easier to complete without delays, and demand is lower—which can lead to better prices.
Winter might offer lower prices due to reduced demand, but the cold and wet conditions can make roofing more challenging. Contractors may need special equipment or face higher risks. That’s why repairs during winter, especially in areas prone to extreme weather, can also be more expensive.
Summer can be more costly, particularly in regions with high temperatures or frequent storms. Extreme heat makes roofing work tougher, and storms can complicate projects. If you need urgent repairs after a storm, expect to pay more due to the immediate need for contractor services.

Investing in a high-quality roof isn’t just about immediate protection. It’s a smart move that can save you money over time. Quality materials like metal, clay, or long-span roofing are more durable and resistant to weather damage, meaning you'll spend less on roof repairs down the line. With proper care, modern roofs can even last 50 years or more.
A solid roof also prevents major issues like leaks that could lead to costly structural damage, mould, or compromised integrity of your home. By avoiding these problems, you sidestep expensive repairs and enjoy peace of mind knowing your home is well-protected.
Energy efficiency is another big plus. Modern roofing materials often come with energy-efficient coatings or reflective surfaces that improve insulation. This keeps your home cooler in the summer and warmer in the winter, further reducing heating and cooling costs over time.
Remember maintenance tasks like gutter cleaning, repair, or gutter guard installation. A high-quality roof reduces the frequency of these chores, saving you time and money. Regular cleaning of your existing roof also becomes less of a hassle when it resists moss and debris buildup.
Lastly, a new, top-notch roof boosts your property’s value and curb appeal. If you decide to sell, potential buyers will appreciate not having to worry about immediate roofing repairs, which could lead to higher offers and a quicker sale.
What to check before hiring a roofing contractor
Before you sign on the dotted line, it's crucial to know you're hiring the right professional for the job. Here are some key things to consider when choosing roofing contractors.
Verify credentials and reputation
Make sure the contractor has the correct licences, certifications, and approvals to perform roofing work. Check if they're members of professional organisations like the Metal Roofing and Cladding Association of Australia (MRCAA) for quality assurance. Also, look out for their roofing qualifications or building licence. For certain roofing materials, like slate or clay tiles, contractors may need specific certifications or training from the manufacturer to guarantee proper installation.
Don't hesitate to ask for references from previous clients or check online reviews and ratings. A solid reputation in the roofing industry speaks volumes about the quality of work you can expect.Â
Make sure you have written contracts and itineraries
Have a detailed contract that outlines the scope of the project, including start and finish dates, materials to be used, and safety procedures. The payment structure should be clear and agreed upon before work begins. Avoid large upfront payments without understanding what they're covering.
It's wise to request quotes from multiple contractors, but be cautious of offers that seem too good to be true. Extremely low bids may compromise on quality. Make sure that the cost includes waste removal, cleaning, and all phases of the project.
Ensure compliance with building regulations
Confirm that the contractor complies with local building regulations. But remember that as the homeowner, you’re responsible for ensuring any required planning permissions are obtained as well. This is especially the case for significant refurbishments or changes.
