How much does it cost to replace a roof?

March 12, 2023


Replacing a roof is a major investment that requires careful planning and budgeting. In Australia, the cost of replacing a roof can vary greatly depending on a number of factors, including the size of the roof, the type of roofing material used, and the complexity of the installation process.

In this blog post, we'll take a closer look at roof replacement costs in Australia, and what factors you need to consider when budgeting for this major home renovation project.


Should you replace your roof?

It seems like an obvious question, but modern technology means the answer isn't as straightforward as it once was. Older roof materials were prone to degradation over time and some simply couldn't be repaired. Asbestos cement roof tiles were popular but couldn't be replaced once they became weathered or broken because asbestos roof tiles aren't being manufactured anymore and replacing them was simply too dangerous anyway. Modern concrete tiled roofs and metal roofs can be repaired and roof restoration and painting are big industries now. Roof repairs and roof restoration are worth considering, especially given that by comparison, roof replacement is the expensive option.

That said, sometimes repairs just aren't enough. In the case of extensive water damage, joists, roof frame and structural beams may need to be replaced. You really won't have any choice but to find a professional roofer to give you some roofing options and to help you with your roofing job. Roofing specialists should be able to tell you whether your roof can be repaired or if it is in such poor condition that it needs to be replaced entirely.

If your roof has been damaged in a storm or by a falling tree, your insurance company might be involved, in which case you'll need to discuss your options with them as well. They will be keen to keep the cost of roof replacement to a minimum and you should push back against any attempt to use the cheapest roofing materials.


Factors that affect the cost of replacing a roof in Australia

There are a number of factors that can have an impact on the cost of replacing a roof including size, material and complexity of your roofing project. Let's break some of those cost factors down:

  • Roof size: The size of your roof is one of the most important factors that affects the cost of replacing it. The larger the roof, the more materials and labour will be required to complete the project. As a result, a larger roof will generally cost more to replace than a smaller one.
  • Existing roof removal: The removal of your current roof is an important first step. In some cases your quote will include removal of current roof tiles, roof cladding, and other materials before new roof installation begins. Asbestos roof removal is more complex and will require specialist handling and disposal. It's important to know what your current roof is made of and whether this will complicate roof removal.
  • Roofing material: The type of roofing material you choose will also have a significant impact on the cost of replacing your roof. There are a wide variety of roofing materials available in Australia, including asphalt shingles, metal roofing, clay tiles, and concrete tiles. Each of these materials has its own unique set of benefits and drawbacks, and the cost of each material will vary depending on factors such as quality, durability, and availability.
  • Complexity of installation: The complexity of the installation process is another important factor that can affect the cost of replacing your roof. If your roof has a complex design or is difficult to access, this will require more time and labour to complete the project, which will increase the overall cost.
  • Additional features: Additional features such as skylights, chimneys, and roof vents can also add to the cost of replacing your roof. These features require additional materials and labour to install, and can significantly increase the overall cost of the project. If you have solar panels or plan to install solar panels once your roof has been replaced, you should discuss this with your roofing contractor.


The average cost of replacing a roof in Australia

So, what can you expect to pay to replace your roof in Australia? According to BorisDoes experts, the average cost of a roof replacement in Australia ranges from $80 to $150 per square metre. However, the actual cost will depend on the factors listed above, as well as the location of your home and the roofing professional you choose to work with.

For example, if you have a large roof that requires a complex installation process and high-quality materials, you can expect to pay significantly more than the average cost per square metre. Similarly, if you live in a remote location or a high-cost area such as Sydney or Melbourne, the cost of your roof replacement may be higher than in other parts of the country.


Tips for budgeting for a roof replacement

If you're considering replacing your roof, it's important to budget carefully and plan ahead to ensure that you can afford the cost of the project. Here are some tips to help you budget for a roof replacement in Australia:

  • Get multiple quotes: To get an accurate idea of the cost of your roof replacement, it's important to get quotes from multiple contractors. This will give you a better idea of the average cost in your area, as well as the range of prices you can expect to pay. Here on BorisDoes you can get multiple quotes from professional roofers, as well as roof repairers, restorers and painters.
  • Consider financing options: If you don't have the cash on hand to pay for a roof replacement, there are a number of financing options available to help you spread out the cost over time. This can include personal loans, home equity loans, or financing options offered by roofing contractors.
  • Plan ahead: If you're planning to replace your roof in the near future, it's important to start budgeting and saving as early as possible. This will give you time to set aside the necessary funds and ensure that you can afford the cost of the project when the time comes.
  • Choose high-quality materials: When it comes to replacing a roof in Australia, choosing high-quality materials is essential for ensuring a long-lasting and durable solution. The harsh Australian climate, with its extreme heat, strong winds, and heavy rain, can take a toll on a roof over time. That's why it's important to select materials that are both strong and resilient. Some popular choices include Colorbond steel, clay and concrete tiles, and shingles. These materials offer excellent protection against the elements and can withstand the harsh Australian weather conditions. Additionally, choosing high-quality materials can increase the value of your property and improve its overall aesthetic appeal. By investing in a quality roof replacement, you can ensure that your home is protected for years to come.



In conclusion, replacing a roof in Australia can be a costly and time-consuming process, but it is essential to ensure the safety and longevity of your home. The cost of replacing a roof varies depending on several factors, such as the size of your roof, the type of roofing material you choose, and the complexity of the installation.
