Colorbond Roofing: Five Benefits and Why it is a Worthwhile Investment
The stability of a home is reinforced by its roof, as this not only contributes to the aesthetic of a home but is also crucial for protection against nature's harshest conditions. While there are many materials available in the market today currently used in homes across Australia, homeowners and commercial establishments should look no further than Colorbond®, the corrugated steel-coated roofing material revolutionised by pioneer Australian steel producer BlueScope Steel. Using Colorbond comes with benefits, and roofers can attest to the growing popularity of Colorbond among new homes and roof replacements. This article features the benefits of using Colorbond and why it is a worthwhile investment.

Easy to maintain
Metal roofs like Colorbond do not demand much maintenance and require lesser upkeep than other materials. Furthermore, as Colorbond utilises an advanced heat-reflective painting technology, its colourfastness makes it look good as new for longer periods of time. As a result, they do not need to be refurbished and repainted often, making it a cost-effective choice. At the very least, rainwater from nature can keep a Colorbond roof clean and debris-free. In cases when manual cleaning is preferred, it can simply be cleaned with pure soap or with a mild non-abrasive kitchen detergent. It also helps to schedule annual inspections from a trusted roofer professional to detect issues early on and, in turn, save money in the long run.
Durable against harsh conditions and corrosion
Colorbond's revolutionary five-layer protection system makes it fireproof, incombustible, and corrosion-resistant compared to other metal roofs. The unique five-layer system is made of:
- Zincalume® steel base.
- A metallic coating layer by BlueScope.
- A pre-treatment layer for adhesion.
- A primer inhibiting corrosion and cracking.
- A heat-reflective coloured topcoat of super polyester pre-painted roof coating.
It is built to counter harsh weather conditions such as strong winds, acid rain, torrential downpours, bush fires, and even lightning.
Apart from harsh weather, Colorbond roofing wards off termites, mould, mildew, and rot from thriving and infiltrating indoors. Compared to tiled roofs, metal is a less conducive environment for the abovementioned species to thrive, lessening structural damage of homes and making roofs last for up to twenty-five (25) years.
High Density Flexibility
Colorbond roofing suits tons of architectural designs, meaning they can be curved, shaped, and be made into straightened sheets to conform to the aesthetic of homes and buildings—be it contemporary, traditional, or heritage. As a result, they can accommodate all sorts of roof pitches or even homes without pitches. Moreover, they come with twenty-two (22) colours to choose from, effectively making it the leading brand offering the most extensive colour variety.
Colorbond boasts being 1/10th the weight of conventional roofing tiles; this lightweight yet sturdy quality is valued by roofers. It makes installation processes faster and more versatile than other corrosive metal roofs and tiled roofs.
Colorbond's ceiling insulation alone effectively minimises rain noise. However, as Colorbond is designed flexible, there is also the option to install a separate noise installation blanket of your choice beneath the Colorbond roof with no problem.
Easy rainwater harvesting
Unlike other roof materials that significantly absorb rainwater, Colorbond's corrugated metal design is sealed from moisture with a coloured topcoat of super polyester pre-painted roof coating with reflective properties. In other words, water and snow easily slide off the surface while protecting the roof surface from mildew, rot, and dampness as its watertight qualities. Colorbond makes rainwater harvesting easier and more manageable with its corrugated roof design. Homeowners might also be interested in integrating a rainwater tank system for a seamless rainwater collection experience. Inquiring with a rainwater tank installation contractor is highly recommended.
Sustainable
Colorbond is energy-efficient. Colorbond utilises the Thermatech® technology for 21 of its colours. The Thermatech technology lowers solar absorbance, which lowers electricity bills associated with ventilation. Meanwhile, solar reflection by Green Star Communities is supported by 5 of the 22 colours Colorbond offers. Colorbond is recyclable. As steel is among the world's most recycled raw materials, purchasing Colorbond contributes to a reduced carbon footprint to an environmentally sustainable lifestyle. In fact, Colorbond has a 36-year warranty on roofs inclusive of maintenance, making full roof renovations less frequent and even unnecessary.
