Roof tiles are made from locally available raw materials like terracotta, clay, concrete, metal and plastic and they are designed to keep out the rain. Roof tiling is popular for many reasons, first, they have thermal acoustic insulation which reduces both heat and noise transfer and with the hot Australian climate, this makes it one of the preferred choices for most households.
Another reason why roof tiling is popular is that they are durable, Welsh slate for example is known to last for 100 years or even more in drier parts of Australia. The recent entrants to the market like solar roof tiles are environmentally friendly and cost-saving in the long run because they not only serve as roofing but also a source of electricity, which makes it appealing to people who want to conserve the environment by going off-grid and reducing the demand of fossil fuels.
Roof tiles also come in different shapes and sizes, which gives the buyer a wide range of options to choose from.
What is Roof Tiling?
NSW Fair Trading defines roof tiling as the fixing of roof tiles to the exterior surface of the roof and fascia structures. This work includes installation of bedding, pointing tiles, battens, sarking, anti-ponding board and associated flashing. It also includes installation of ventilators, skylights and the like but does not involve structural alteration of roof members or components to tiled roofs.
In Australia, all roof tiling work over $5,000 in labour and materials must be done by a licensed individual, according to NSW Fair Trading. ‘Roof tile’ does not include roofing shingles, slates, shakes or imitations of these, this falls under a different process called roof slating.

What’s the difference between Roof Tiling vs. Colorbond Roofing
Roof tiles have been around for thousands of years and are made from locally available raw materials like terracotta, clay, concrete, metal and plastic. Colorbond on the other hand is relatively new, it is made of steel and is available in a wide variety of colors. Both are equally popular in Australia for various reasons, but there are significant differences between each that are worth noting.
Durability: Roof tiles are known to last for over 50 years if regularly maintained, repaired and restored. They are known to withstand hail, strong winds and fire and usually come with a 50-year warranty. Colorbond on the other hand is light and strong. It is termite resistant, fire resistant, and can endure extreme wind. They also don’t corrode, chip, peel or crack and come with a 30-45-year warranty.
Style: There are various types of roof tiles to choose from i.e. terracotta, concrete, slate and solar, they also come in a wide range of colors giving you a wide variety to choose from. Colorbond on the other hand comes with over 20 different colors to choose from.
Weight: Roof tiles are generally heavy and as such it can keep out noise, its thermal mass also helps to regulate temperatures inside the house and provide thermal insulation. Colorbond is a highly thermal efficient material and can insulate the house from extreme temperatures. However, because it is made of steel, which is light, it does not keep out noise and it can be noisy especially in storms and hail.
Maintenance: Though tiles are known to be durable, they can become brittle in certain weather conditions and can suffer damage if walked on or struck by falling trees making the maintenance process difficult and costly. Colorbond on the other hand is easy to maintain because it is very resistant to cracks and walking on a Colorbond roof can be safer as you are less likely to cause damage.
