When you think of a typical Queenslander, apart from the massive stilts and open-plan design, one of the most recognisable qualities is the corrugated iron roof.
Since the 1840s when Australia was first developing, corrugated iron has been considered one of the best materials to use for roofing. Because of it’s lightweight, sturdy properties, it is the ideal material to use in terms of easy transportation and construction as well as protection.
Although it is a relatively strong, fire proof and weather-resistant material, if exposed to water (particularly salt) rusting is inevitable. This is why it is extremely important to coat the steel in a layer of paint in order for it to remain protected.
Even today this roofing remains to be one of the most popular choices in materials for a range of reasons. Its flexibility, strength and thin sizing allows for quick repairs, relatively cheap installation and durability with little maintenance.
Apart from the practical side of things, there is also the aesthetics. The typically 3 inch curves rolling into one another create a very symmetrical feel, breaking up the angles of the rest of the house and creating a harmonious contrast.
Since iron is quite a durable material itself, compared to wood it is very easy to prepare for installation. Instead of needing to purchase an expensive sealant, a few layers of paint will generally be enough to prevent any damage.
One aspect of corrugated iron that can pose a genuine issue is the fact that the wavelengths of most sounds are echoed loudly into the tube of the corrugated iron. This means that any noise close to or coming into contact with the roof is going to release a high pitched “ping”. This can be a genuine issue for Queenslanders as falling tree branches and wildlife are a part of our every day lives.
On the other hand, the echo can be the perfect culprit to amplify raindrops into a soothing lullaby and because of the shape of the typically 3 inch tubing and smoothness of the iron, the water runs straight down and off the roof, making cleaning very manageable. Also because it is a very thin material it allows the house to stay cool in the warm summers, making it the ideal choice for a house in Queensland.

The iron sheets themselves are relatively cheap and can be purchased with a coat of Colorbond or made galvanised to order. They range from around 5 to 45 dollars per sheet depending on the size of the sheet and what coating you have selected.
Compared with other common roofing materials such as clay, slate, concrete, wood, Spanish and asphalt, corrugated iron is often said to be one of the most durable and certainly one of the most cost-effective.
So whether it’s the classic sound of rain on the tin roof, or the practical desires of someone looking for a sturdy home, or anyone who doesn’t want to waste their precious pennies, it is no surprise that corrugated iron is one of the most popular choices in Queensland.
