Advantages of steel roofing

Colour range

One of the standout features of steel roofing is its diverse colour range. Unlike some roofing materials, steel offers homeowners a broad palette to choose from, allowing for a customised look that seamlessly blends with the overall aesthetic of their homes.

COLORBOND* steel offers a wide range of standard colours as well as options for custom colours for unique projects. With 22 standard colours, the COLORBOND steel palette offers a wide range of colours to meet diverse needs.

Thermal efficiency

Steel roofs cool rapidly after dark in the summer, contributing not only to energy efficiency but also to a more comfortable living environment. This thermal efficiency is a practical advantage, especially in regions with scorching daytime temperatures.

Design flexibility

The design flexibility of steel roofing sets it apart from other materials. Its ability to accommodate various pitches and curves makes it a preferred choice for architects and homeowners looking to achieve unique and creative designs.

“Customisation is key when it comes to the aesthetic appeal of steel roofing; homeowners can achieve a personalised look through careful selection of colour and profile options,” says Walsh. “Colours are largely guided by the COLORBOND steel range.”

100% recyclable

For environmentally-conscious homeowners, the sustainability factor is crucial. “Steel roofing, being 100% recyclable, aligns with eco-friendly practices, reducing the environmental impact associated with construction materials,” says Walsh. 

Lower weight

Compared to traditional tiles, steel roofing boasts a lower weight, offering practical benefits for various architectural designs. The reduced weight simplifies the overall construction process and can lead to cost savings. Both concrete and terracotta tiles weigh 50-60kg /m2 (depending on the make/type); in comparison steel is a minuscule 5kg.

Enhanced security

Steel roofing provides an added layer of security. “It’s more secure – you can lift a tile to get access to the roof-space and home but lifting steel is more complicated.”

Advanced weatherproofing

Superior weatherproofing is a hallmark of steel roofing. It offers long-term protection against the elements, ensuring durability and minimising the need for frequent maintenance or repairs.

Types of steel roofing options

When considering steel roofing options, homeowners can choose from various types, each catering to specific needs and preferences:

Corrugated

Known for its traditional aesthetic, corrugated steel roofing is a cost-effective option suitable for a wide range of applications.

Steel Clad 762

Steeline Steel Clad is a modern, stylish, high-strength, lightweight roof and wall cladding material. Made from high-tensile steel, the profile has been engineered to give the highest strength and rigidity possible, whilst using the least material.

Steeline Steel Span 700

It has an efficiently designed trapezoidal profile, which provides great strength, rigidity and water carrying capacity, making it light and able to span long distances.. The trade-off  is a slightly reduced coverage, ie 700mm instead of 762mm – about 8% less coverage.

Lokdek with concealed fixings

For those seeking a clean and streamlined look, Lokdek with concealed fixings offers a polished and contemporary design.

Architectural/standing seam

This option provides a modern and sleek appearance with raised seams, combining aesthetics with durability for a sophisticated finish.

Low-pitched for water carrying

Even in regions with heavy rainfall, correctly profiled, low-pitched steel roofs ensure efficient water drainage, giving better flexibility than other roofing types.

Durability & maintenance

Steel roofing is renowned for its durability, with popular choices like COLORBOND steel offering up to a 30-year warranty. “Steel roofing is virtually maintenance-free,” says Walsh, “as it’s washed by the rain.”

Environmental impact 

For those prioritising environmental sustainability, steel roofing has some advantages.

“Making steel is currently carbon intensive, but once made it has a very long life. It’s often reusable and 100% recyclable.”

Insulation & energy efficiency

Insulation plays a pivotal role in optimising energy efficiency for homes with steel roofing. Homeowners can achieve a 7-star energy rating by selecting appropriate insulation products designed specifically for use with steel roofs and cladding.

Extreme weather challenges

Steel roofing proves its resilience in regions prone to extreme weather conditions:

High winds

“Fasteners come into play in cyclonic areas. Steel is preferable to most other roofing materials because it can be fastened very well,” says Walsh.  

Marine environments

For coastal homes, corrosion-resistant steel products are available, ensuring longevity and durability in marine environments.

Snow Loads

“It’s great in alpine environments, with high pitched roofs allowing snow to slide off the roof. It’s also strong to hold snow that has fallen.”

Cost considerations

While the initial cost may vary, steel roofing offers competitive pricing. The overall expense depends on the options chosen by the architect and the time required for installation. Homeowners should consider the long-term benefits, which often outweigh the upfront costs.

Warranties & guarantees

COLORBOND steel, a popular choice for steel roofing, provides warranties of up to 30 years (for up to 45 degrees), offering homeowners peace of mind and long-term protection for their investment.

As the roofing industry continues to evolve, steel remains a reliable and forward-thinking choice for those looking to enhance both the form and function of their homes.
