Roof tiling can be a major home improvement, but how much does roof tiling cost? Costs of roof tiles vary and so do installation costs. Together, one roof can cost far less than another roof of the same size because the pitch and complexity of a roof design will affect the cost as will the cost of roof tiles.
The roof pitch can make a difference to the number of tiles needed to cover a roof. A steeper pitch takes up a larger area than a gentle pitch and if there are several different pitches, it could cost more.
For example, a home of 100 square metres will need approximately 112m2 of roof tiles. If it has a steeper pitch or a more complex shape, it will require more tiles. The best way to determine how many square metres of tiles you need is to look at a drawing of your house and measure the roof area. If you don't have drawings of your house, a roofing contractor can accurately tell you how many square metres of tiles you need based on their previous experience.
Concrete roof tiles are the least expensive type of roof tiles, but today's concrete roof tiles can be beautiful and long lasting. In general, concrete roof tiles cost between $40 and $60 per square metre. A house that is 100 metres square will have a roof of approximately 112 square metres, so the total cost will be between $4480 and $6720 for the tiling only. As mentioned above, a steeper pitch or complex shape will require more tiles.
Terracotta roof tiles are more expensive than concrete roof tiles. On average, they cost $80 to $110 per square metre. Using the 112 square metre cost, they might cost between $8960 and $12,320 or almost double the cost of concrete roofing tiles.
Slate is one of the most expensive roofing tiles you can buy. It can cost between $200 and $500 per square metre. The difference in price has to do with the quality of the slate. A 112 square metre roof in slate can cost between $22,400 and $56,000 and may be unaffordable for most homeowners.
Slate roofing does have the advantage of being long lasting. Slate roofs have been known to last for centuries and slate comes in a variety of colours and can make a spectacular roofing material. It's not for every home, though and installation costs will also be higher.
Solar roofing tiles are now available in Australia. Our article, The Future of the Solar Panel is Cheaper and Integrated into Your Roof explains how solar tiles work and mentions three companies that sell solar tiles. Three companies that sell solar roofing tiles are:
You don't have to cover an entire roof with solar roof tiles. They are best used where the sun strikes the roof and can produce electricity. Solar roof tiles can be expensive, but only about 375 tiles are needed to produce 5 kilowatts of power. Over time, solar roof tiles can pay for themselves because of the savings on electricity.

Solar roof tiles can look like slate, terracotta or come in colours. Prices vary, but solar roofing tiles can cost anywhere from $8,000 to $18,000 depending on the brand and the style. Some solar roofing tiles cost $230 per square metre and prices are coming down as more competition pushes prices down. Solar roofing tiles come with long warranties, from 25 years to infinity in the case of Tesla roof tiles. Some are made from toughened glass and can be impervious to breakage. They do need to be washed down occasionally, though, to retain their ability to absorb the sun's rays.
Should you choose metal or roof tiles? Roof tiles have several advantages over metal roofs:
Metal roofing is relatively easy to maintain, but may lack the beauty of roof tiling because metal roofing comes in flat profiles, while roof tiles can be curved or flat.
Roof tiles are more expensive to lay than metal roofing. On average, the cost of laying roof tiles is between $80 and $100 per square metre. Metal roofing costs between $50 and $60 per square metre. On a 112 square metre the difference can be:
On average, the cost of installing roofing tiles is between $80 and $120 per square metre. Metal roofing costs between $50 and $70 per square metre. Between the cost of roofing tiles and installation, roofing tiles can be more expensive than metal roofing, but may be perfect for your roof. They often come with long warranties and can be integrated with solar roofing tiles.
When choosing a roofing installer, price will be just one consideration. Also ask if the roofer is licensed and insured. They should also be able to give you references and be able to give you a written quote. If all things are equal, you can choose a lower quote, but only if you have inspected their previous work.
If you are replacing a roof, the costs will be higher because the roofers will have to remove the old roof first. If you are replacing a metal roof with a tile roof, the costs may be higher because they will have to reinforce the roof and make the roof able to be tiled. How Much Does Roof Replacement Cost? covers the costs of roof replacement. The cost will depend on several factors:
When choosing a roofing replacement specialist ask the same questions you ask a roof installer. Also ask for examples of their previous work and insist on an itemised quote so you know exactly what you are paying for. They may also charge for removing old roofing materials and taking them to the tip. Expect to get a firm quote after a roof replacement service inspects your roof.
Replacing the roof may cost between:
These costs will include replacing an old roof. The price differences reflect the complexity of the job. A lower price will be a relatively straight forward job, while a higher price may mean structural work is needed or a roof has a steep pitch or complex design.
Whether you're purchasing a new roof for a new home or replacing a roof, roof tiling is worth considering. It can be a beautiful addition to a home and can increase its value. Concrete tiling is the least expensive option, but also consider terracotta, slate and solar roof tiles. A combination of tiles including solar roof tiles can save you money in the long run and may be a good home improvement investment.
