How much does reroofing cost?

The biggest factor that will affect how much reroofing costs is the roofing material you choose. The cheapest roofing material is concrete tiles, followed by steel and then clay/stone tiles with Colorbond roofing price at the top end of the scale.

Roofing is priced per square metre. Expect to pay in the range of:

• $8 to $10 per square metre for sarking
• $40 to $60 per square metre for concrete tiled roofing
• $50 to $70 per square metre for steel roofing
• $80 to $110 per square metre for terracotta tiled roofing
• $200 to $500 per square metre for traditional slate tiled roof

Quotes for reroofing cost will be based on the size of your roof and the complexity of the roof design. For example, a simple gable roof will be less expensive per square metre than multiple gables.

The most common types of roofing

Roofing can be made out of many materials and they each come with different costs and benefits. common types of roofing materials are:

Metal roofing

Metal or steel roofing includes treated zinc-aluminium (also known as Colorbond) and untreated zinc-aluminium. Metal roofing is very flexible, durable and should come with a warranty of at least 25 years.

Compared to tiles, metal roofing is more affordable to install and easier to maintain. The cost of supply and installation can vary widely, but generally expect to pay around $50 to $70 per square metre for high-quality metal roofing.

Colorbond is one of the most popular roofing materials in Australia as it can be very cost-effective. Replacing a roof with Colorbond can cost:

• Concrete tiles - $20, 000
• Asbestos cement roof - $15,000 - $20,000
• Metal roof - $6,000 - $10,000

Tiled roofing

Tiled roofing– typically terracotta, clay, concrete or slate – is frost-resistant and comes in a variety of finishes. Tiles are also non-combustible, making them a good choice in bushfire-prone areas. Tiles generally cost more than Colorbond roofing and will require sarking to be installed, the insulation layer between the roof and wall. 

Most tiles in Australia are designed to resist the heat and frost of our climate making them a great option. One of the major advantages they have is that individual tiles can be replaced rather than whole sections as with a Colorbond or other metal roof. 

Concrete and asphalt tiles 

They are affordable tile options and they are very durable, many come with a guarantee of lasting for at least 50 years. They come in different styles and colours to match your home and designs. 

For a 200 Square meter roof, expect to pay around $8,000 - $12,000 for concrete or asphalt tiles.

Terracotta tiles

They are a more expensive option to install but many Australians find the look they give to be worth it. They are also one of the most durable roofing materials and will last longer than most other roofing. 

For a 200 Square meter roof, expect to pay around $16,000 - $22,000 for terracotta tiles.

Slate tiles

They can be expensive as well but some offer lifespans of 75 years. Their incredible durability is a major part of their cost but if cared for well, they can even last for centuries. 

For a 200 Square meter roof, expect to pay around $40,000 - $100,000 for slate tiles.

The cost of tile roofs varies, but as a rule of thumb, tile roofs cost between $80 to $110 per square metre, supplied and laid. If you are worried about paying too much, another way to think about the cost of replacing a roof is that it should add up to 2% - 4% of the value of your home.

What affects reroofing cost?

If you have to replace your roofing, it's important to have an idea of the reroofing cost. The 4 main factors that will determine your new roof cost are:

• The roofing material you choose
• The size of your roof, in square metres
• The pitch or angle of your roof
• What does your roofing contractor charge for labour

Roof replacement cost will be more expensive if you have a steep roof pitch, an asbestos cement roof or your site is difficult to access.

Reroofing cost is lowest for simple roofs with single or double pitches, easy access and average-sized roofs.

How much does roof replacement cost?

In addition to the new roof cost, you'll also need to account for removal and disposal of the existing roofing material to get an idea of your overall roof replacement cost. 

To strip and replace roofing (for an average-sized 3-bedroom family home), expect to pay in the region of:

• $6,000 to $10,000 to replace an existing metal skillion roof with Colorbond
• $20,000 to replace existing tiles with Colorbond
• $15,000 to $20,000 to replace an existing asbestos cement roof with Colorbond

For other materials expect to pay: 

• $8,000 - $12,000 for 200 square meters of concrete or asphalt tiles 
• $16,000 - $22,000 for 200 square meters of terracotta tiles
• $40,000 - $100,000 for 200 square meters of slate tiles

Hiring a roofer

Due to the safety implications and specialist skills required, reroofing is not recommended as a DIY project. Only a qualified roofing contractor has the equipment and skill needed to do the job right.

Most states and territories in Australia require roofers to be licensed. Depending on where you live, they could hold a dedicated roofing licence such as roof tiling, roof slating (NSW), roof cladding (Queensland) or a building licence (Victoria). Ask your roofing contractor about their licence before you hire them.

Other questions to ask roofers include:

• Are you insured to work in my home?
• Can you provide a written quote?
• How long is the warranty on your materials?
• Do you have references I can follow up on?

Getting quotes for roofing

Find out how much your project will cost by getting quotes from local roofers. This will give you a sense of what market rates currently are. No matter the size of your roofing job, always request a fully itemised quote for reroofing cost including the cost of all materials used.

Also, think about whether or not you want your guttering and downpipes to be replaced at the same time your new roofing is laid. If so, ask for these to be included in your quotes. Any roofing quote should include removal and disposal of the existing roof materials, replacement materials (including sarking insulation) and final tidy-up. You may also want your roofing repaired or restored.

• $5,560 to $8,340 for concrete tiles 

• $6,950 to $9,730 for metal roofing

• $27,800 to $69,500 for slate roof tiles
