A new roof is one of the bigger investments you will make in your home, so it is natural to want a sense of the cost before you start. The honest answer is that roof replacement cost varies a lot from home to home, because no two roofs are exactly the same. What follows is general guidance to help you plan, not a fixed quote.
Understanding the factors affecting roof cost will help you have a more informed conversation with your roofer, and understand why an on-site assessment is so important. Here is what goes into pricing a new metal roof.
The short answer: There is no single price for a new roof, because cost depends on your roof’s size, pitch and complexity, the material and colour you choose, removing the old roof, and site access. Quality Colorbond is a bigger upfront investment but is durable and low-maintenance, which can make it more cost-effective over the life of the roof. Because so many variables are involved, the only accurate figure comes from an on-site assessment and detailed quote.
What affects the cost of a new roof?
Several things influence the final price, and they add up differently for every property.
Roof size, pitch and complexity
The biggest driver is simply the size of your roof, measured in square metres. A larger roof needs more materials and labour. Pitch and complexity matter too. A steep roof, or one with lots of angles, valleys, hips and penetrations like vents and skylights, takes more time and care to do properly than a simple, low-pitch design.
Materials and colour choice
The material you choose affects both cost and performance. IM Metal Roofing works with 100% Australian-made Colorbond, which is designed to handle coastal conditions, along with Zincalume where suitable.
Colorbond and Zincalume options
Colorbond comes in a wide range of colours and profiles, while Zincalume offers a durable unpainted finish. The right choice depends on your home, your budget and the look you are after. If you are weighing up materials, our comparison guide can help.
Removing the old roof and site access
Replacing an existing roof usually involves removing and disposing of the old one first, which adds to the labour. Site access also plays a part. A single-storey home with easy access is more straightforward than a multi-storey or hard-to-reach roof. Any repairs to the structure underneath, or upgrades to gutters and downpipes done at the same time, will also factor into the overall cost.
Repair, restore or replace?
A new roof is not always the only option, and the most cost-effective path depends on your roof’s condition.
When a full replacement is the better long-term value
If your roof is simply ageing but structurally sound, a roof restoration or targeted roof repairs may be all you need. But if the roof has widespread rust, ongoing leaks or is at the end of its life, a full metal roof replacement is often the smarter long-term investment. It gives you decades of protection and avoids the cost of patching the same problems again and again. Our guide on restoring versus replacing goes deeper on this decision.

General figures online only tell you so much, and can be misleading.

FAQs
Q: Why can’t you give me a price over the phone?
A: Roof cost depends on size, pitch, complexity, materials, access and the condition of the existing roof. Without seeing the roof, any figure would be a guess. An on-site assessment lets us give you an accurate, detailed quote rather than a rough estimate.
Q: Is a metal roof more expensive than other options?
A: Metal roofing is a long-term investment. While upfront costs vary, quality Colorbond is durable, low-maintenance and well suited to coastal conditions, which can make it more cost-effective over the life of the roof. We can talk through the options for your budget.
Q: Do you remove the old roof as part of the job?
A: Yes. A full replacement typically includes removing and disposing of the existing roof before installing the new one. This is factored into your detailed quote so you know exactly what is included.
