Australian Roofing Guide 2026: Tiles Costs, Types, and How to Choose
In Australia, roofing is not just about choosing materials. It’s about understanding how different systems impact pricing, installation, and long-term performance.
For roofers, understanding how roofing works in their area is critical. Material selection, costs, labor, climate conditions, and customer expectations can vary significantly depending on the region.
Most residential roofs are built using either metal or tiles, with concrete and terracotta tiles being the most common options. Each material requires a different approach when it comes to measuring, estimating, and installation.
This guide breaks down what you need to know to choose the right material and quote tile roof jobs accurately.

Roofing Materials in Australia, Why Tiles Dominate
Roofing materials in Australia are heavily influenced by climate, durability requirements, and long-term performance.
From hot, dry regions to coastal areas and alpine environments, roofers need materials that can handle extreme heat, UV exposure, moisture, and temperature changes. This is why material selection in Australia looks very different compared to other markets.
The three most common roofing options are:
- Metal roofing
- Concrete roof tiles
- Terracotta roof tiles
The choice between metal and tile roofing often comes down to a trade-off between installation speed, insulation performance, and long-term durability.
Asphalt shingles exist, but they are rarely used in residential construction. Most homeowners and builders prefer materials that perform better under harsh weather conditions and long-term exposure.
For contractors, this means most jobs will involve either tile roofs or metal systems, each requiring a different approach to measuring, estimating, and installation.
Metal Roofs
Metal roofing is widely used across Australia, especially in modern builds and large-scale projects.
Materials like Colorbond and Zincalume by BlueScope Steel are industry standards, known for their durability and performance in harsh conditions.
Metal roofs are lightweight, require minimal maintenance, and are typically installed as sheet systems over battens or purlins. In some cases, they can be installed directly over the structure, although this is less common in residential projects.
They perform well in harsh environments, including heavy rain and strong winds, and offer good resistance impact, corrosion, and UV exposure when properly coated. However, compared to tile systems, metal roofs provide lower natural insulation and can transfer heat if additional insulation layers are not included. They are also more susceptible to dents under impact.
With proper coating and maintenance, metal roofs typically last between 40 and 70 years. In terms of cost, materials usually range between $50 and $120 per m², depending on the system and finish.
Overall, metal roofing remains a popular choice in Australia due to its combination of durability, low maintenance, and reliable performance in extreme weather conditions.
Concrete Roof Tiles
Concrete tiles are one of the most common roofing materials in Australia due to their balance between cost and durability.
Compared to metal roofing, concrete tiles are heavier and require a tile system that allows each piece to be installed individually on battens. While this adds complexity to the installation, it also contributes to their overall performance and longevity.
Concrete roof tiles are not only an affordable option, but they also provide better natural insulation than metal roofing. This makes them well suited for hot climates, as they help reduce heat transfer into the building. They also perform well in extreme weather conditions when properly installed.
With proper maintenance, concrete roof tiles typically last between 30 and 50 years.
Manufacturers like Monier and Boral Roofing offer a wide range of profiles and finishes used across residential projects. The average cost, without considering installation, is around $40-$70 per m² , excluding installation.

Terracotta Roof Tiles
Terracotta tiles are a premium roofing option, known for their higher cost and distinctive aesthetic, often used in architectural and high-end homes. The name comes from the Italian term meaning “baked earth,” reflecting the clay-based material that gives these tiles their durability and long-lasting finish.
Terracotta tiles offer excellent thermal insulation, helping regulate indoor temperatures in hot climates. They are also highly resistant to UV exposure and perform well in coastal environments, making them a reliable option for harsh conditions.
In terms of durability, terracotta roofs can last between 50 and over 100 years with proper installation and maintenance, while maintaining their color over time with minimal fading. However, they do have low impact resistance, in areas that experience hailstorms like Queensland, New South Wales and parts of Victoria this can be a problem.
While impact resistance is lower, damaged tiles can typically be replaced individually without affecting the entire roof.
As a premium material, terracotta tiles come at a higher cost, typically ranging between $80 and $150 per m², excluding installation. It is also important to consider that these tiles are more fragile during installation, which can make them more complex to handle compared to other materials.
Brands like Bristile Roofing specialize in clay-based tiles designed for long-term durability and consistent color.
How to Measure and Quote Tile Roof Jobs
Tile roofs require more precision than many contractors expect. Small miscalculations can lead to material shortages, reduced margins, or costly delays.
- Start with accurate measurements: It is important to measure the total roof area rather than just the building footprint, and to account for pitch in order to calculate the true surface area. Even small errors at this stage can lead to incorrect estimates and impact the profitability of the job.
- Factor in waste: Tiles require overlap, and additional materials are often needed to account for cuts and breakage during installation. Underestimating waste can quickly lead to shortages and unexpected costs.
- Estimate materials correctly: Material estimation varies depending on the tile profile and roof design. Tile coverage per m² can change, so it’s important to include ridge caps, battens, and other roof components in your calculations.
- Do not underestimate steep roofs: Steeper roofs increase complexity, affect waste factors, and can make installation more time-consuming, all of which should be reflected in the quote.
- Where contractors lose time: Manual measurements, recalculation estimates because of errors, and multiple site visits make you waste valuable time you could spend getting more clients.
Many contractors lose time in this process due to manual measurements, repeated calculations, and multiple site visits caused by estimation errors.
Using digital tools like iRoofing allows contractors to measure roofs, generate estimates, and build quotes directly from their phone, reducing errors and saving time on every job.
Key Takeaways for Roofing Contractors
- Tile and metal roofing dominate in Australia, with concrete and terracotta tiles being the most common for residential projects
- Concrete tiles offer the best balance of cost and durability, typically lasting 30 to 50 years with good insulation performance
- Terracotta tiles provide the longest lifespan, often lasting 50 to 100+ years, with superior insulation and resistance to harsh conditions
- Metal roofing is faster to install and performs well in extreme weather, but requires proper insulation to manage heat transfer
- Roof pitch, waste, and tile profile directly impact material estimates, making accurate measurements critical for profitability
- Small estimation errors can lead to material shortages or reduced margins, especially on complex or steep roofs
- Using digital tools like iRoofing helps contractors measure, estimate, and quote faster, reducing errors and saving time on every job
