If you own a home with a tiled roof or you are planning a new build, understanding roof tiles is important. Not all tiles are the same. They come in different materials, profiles, and price points, and the right choice depends on your home’s style, your local climate, and your budget.
This guide explains the main types of roof tiles, how they perform in Australian conditions, how long they last, and what to watch out for as they age.
What Exactly Are Roof Tiles?
Roof tiles are individual units of material laid in overlapping rows across a roof structure to shed water and protect the home below. They have been used for centuries and remain one of the most popular roofing choices across Australia. Tiles are generally held in place by gravity and the overlap between units, along with mechanical fixing in areas prone to high winds.
In Australia, the most widely used types are concrete tiles and terracotta (clay) tiles, though other materials are also available.
What Types of Roof Tiles Are Available in Australia?
What Are Concrete Roof Tiles?
Concrete tiles are the most common type of roof tile installed on Australian homes over the past 50 years. They are made from sand, cement, and water, and are available in a wide range of profiles and colours. Key characteristics include:
- Generally more affordable than terracotta
- Available in flat, low-profile, and high-profile shapes
- Can be painted or have a colour coating applied
- Heavier than some other materials, requiring a strong roof structure
- Can absorb moisture over time, which increases weight and may promote moss growth
- Typically last 40 to 50 years with proper maintenance
The colour coating on concrete tiles tends to fade over time and may need repainting as the roof ages.
What Are Terracotta or Clay Roof Tiles?
Terracotta tiles are made from natural clay that is shaped and fired at high temperatures. They have been used for centuries and are widely regarded as a premium roofing material. Key characteristics include:
- Excellent durability, often lasting 50 years or more
- Naturally resistant to fading, as the colour comes from the clay itself
- Heavier than concrete tiles and require a properly engineered roof structure
- More expensive than concrete tiles to supply and install
- Very resistant to fire
- Perform well in hot climates due to natural thermal properties
Terracotta tiles are a good long-term investment for homeowners who want a premium product that holds its appearance over time.
What Are Slate Roof Tiles?
Slate is a natural stone that has been used as a roofing material for hundreds of years. It is extremely durable and can last well over 100 years when maintained properly. However, it is rare in Australian residential applications due to its high cost and weight. It is more commonly found on heritage or prestige properties.
What Are Synthetic or Composite Roof Tiles?
Synthetic roof tiles are made from man-made materials such as rubber, plastic, or polymer composites. They are designed to mimic the appearance of natural slate or wood shake while being lighter and more affordable. They are not widely common in Australia but are available for specific applications.
What Are the Advantages of Tiled Roofs?
- Aesthetic appeal: Tiles give homes a classic, traditional appearance that many homeowners prefer
- Thermal mass: Tiles naturally absorb and slowly release heat, helping to regulate indoor temperatures
- Sound insulation: Tiled roofs tend to be quieter in heavy rain compared to metal roofing
- Longevity: Quality tiles, properly maintained, can last 40 to 100 years depending on the type
- Fire resistance: Both concrete and terracotta tiles have good fire-resistance ratings
What Are the Disadvantages of Tiled Roofs?
- Weight: Tiles are significantly heavier than metal roofing, requiring a stronger roof frame
- Fragility: Individual tiles can crack or break from impact and are difficult to walk on safely
- Maintenance: Ridge capping can loosen over time, and moss or lichen can build up in humid climates
- Leakage points: Cracked or missing tiles are a common source of leaks
- Fading: Concrete tiles in particular can lose their colour coating over the years
- Cost of replacement: Replacing tiles on a full roof can be more labour-intensive and expensive than metal re-roofing
How Long Do Roof Tiles Last?
The lifespan of roof tiles depends on the material, the quality of installation, local weather conditions, and how well the roof has been maintained. As a general guide:
- Concrete tiles: 40 to 50 years
- Terracotta tiles: 50 years or more, sometimes up to 100 years
- Slate tiles: 100 years or more
That said, other components of a tiled roof, such as the bedding and pointing on ridge caps, the sarking beneath the tiles, and the battens, have shorter lifespans and typically need attention every 15 to 20 years.
When Should You Consider Replacing Tiles with Metal Roofing?
Many homeowners with aging tiled roofs choose to convert to metal roofing when it comes time for a replacement. This is sometimes called a tile to metal conversion. Reasons people make this switch include:
- Metal roofing is lighter, which reduces load on the roof frame
- Colorbond and Zincalume have strong corrosion resistance, especially in coastal areas
- Metal roofing systems require less ongoing maintenance
- Modern Colorbond roofing comes with long manufacturer warranties
- Metal roofing systems are less prone to individual component failures such as cracked tiles
