What metal should you choose for your metal roofing installation?

So you’ve decided on metal roofing installation for your home – a wise decision, if you ask us.

That’s the first major resolution out of the way.

Of course, when it comes to something as important as your roof, there will be many other decisions you’ll have to make.

Chief among them, what type of metal you should choose for your roof.

That may include:

  • The base metal itself
  • Coatings applied
  • Specific alloy/blend

Each of these can have a dramatic impact on how long your roof lasts, as well as how much effort is needed to take care of it.

There are many options out there – so many that it can make your head spin!

That’s what we’re here! Join us on this through your metal roofing options, as we explain which choice is best for your home.

New metal roofing 101: what are the types of metal available?

A metal roof is not a single roofing product – rather, it’s a blanket term that covers an entire range of different metal roofing products.

When it comes to your roof, you’ll have a range of different options, including…


While not really a popular choice now, for a long time copper was the go-to metal roof installation – in fact, for a long time it was basically the only option!

Perhaps the oldest option around, copper is incredibly long-lived. Some of the world’s oldest metal roofs made use of this material – not to mention, it looks great.

The problem: copper is also one of the most expensive options.

Increasingly, copper is joining silver and gold and becoming a rare metal thanks to skyrocketing demand – that’s why copper theft is suddenly starting to make headlines

Another downside of copper is how it changes colour – a side-effect of its durability and long-life.

Simply put, a copper roof won’t stay that beautiful copper brown colour.

Over time, it develops a green patina – that is, a protective layer that protects it from rust and other conditions.

Don’t believe us? Just look at the Statue of Liberty – over the years, she changed from her original copper to today’s blue-green!


While often used to create a rust-proof layer, some roofs are made exclusively of zinc.

Sure, you might not see zinc being used often for metal roofing installation in Melbourne – however, it’s an extremely popular choice in Europe, with almost 90% of Paris roofs made of the metal!

90% – if that isn’t a vote of confidence, we don’t know what is!

Of course, there’s a reason zinc hasn’t taken off down under.

In particular, some experts claim that the underside layer of zinc roofing is especially vulnerable to corrosion (and by extension, leaks).

Not to mention, zinc is a soft metal – it has a Mohs hardness score of 2.5 (barely better than gold, a metal notorious for its softness!)

This makes it much easier to damage.

That might not be a problem in Paris with its consistent climate – for a city as unpredictable as Melbourne hover, this poses a real problem, and makes zinc less-than-ideal as a standalone.


Aluminum is one of the most commonly-used metals in the world.

You’ll find it in soft drink cans, aviation, cooking utensils… and occasionally in metal roofing installations!

When it comes to roofing in particular, aluminium is often recommended for its:

  • Resistance to harsh weather
  • Light weight
  • Abundance
  • Corrosion resistance

Of course, aluminium isn’t perfect. It’s prone to discoloration and fading – not an image you want associate with your house.

Not only that, but it’s also one of the weaker metals, with a Mohs hardness rating of 2.5-3 (for reference, steel sits at around a 5).

Again, if you want your metal roofing installation to go the distance, aluminium’s relative weakness may not make it the best option!


When it comes to metal roofing installation in Melbourne, steel rules the roost, and for good reason.

In our experience, steel offers the best all-round value. It’s tough, durable, resists dents and strong, all in a single package. 

Of course, not all steel is made equal.

There are many manufacturers of steel panels for metal roofing out there – if you ask us however, there’s one that stands out in particular (and which we endeavour to use for as many roof installation jobs as possible!).

COLORBOND metal roofing is a brand of steel created by BlueScope Steel.

What sets it apart from straight up steel roofing is its unique formulation.
