How Much Does It Cost to Install a New Roof on a House?
Getting a new roof for your home isn’t something that happens often. So when it does, it’s a big deal—not just for how your house looks, but for your wallet too. Whether your roof is leaking, falling apart, or just plain old, it’s normal to wonder: what’s the real cost to install a new roof?
Truth is, there’s no one-size-fits-all answer. It all depends on a few key things—like the size of your roof, what it’s made of, and who’s doing the job. But don’t worry, we’ll break it all down in a way that’s easy to understand, even if you’ve never replaced a roof before.
Let’s dive into what really goes into the cost to install a new roof, and what you should keep in mind before you bring in the pros.
So, What Actually Affects the Cost to Install a New Roof?
Think of your roof like a pizza—bigger size, fancier toppings, thicker crust, and extra layers? That’s gonna cost more. Same goes with roofing. The total price can swing a lot depending on things like:
- Roof size (square metres) – More space means more materials and more labour.
- Material type – Metal, tiles, shingles, slate… each has its own price tag.
- Roof pitch (steepness) – The steeper it is, the harder and riskier it is to install.
- Labour costs – Roofers don’t work for free, and experienced ones are worth it.
- Location – Prices in cities might be higher than in small towns.
- Old roof removal – Ripping off the old stuff takes time and adds to the bill.
- Structural repairs – If there’s hidden damage underneath, that’ll cost extra.
You’ll find that the cost to install a new roof usually ranges from $8,000 to $25,000+ in Australia for the average home. But if you’ve got a large or high-end house, it could go beyond that.
Different Roofing Materials and Their Costs
The material you choose plays a huge role in the total cost. Here’s a quick look at common options and what they might set you back:
Roofing Material | Average Cost per m² (Installed) | Lifespan |
Asphalt Shingles | $90 – $150 | 15–25 years |
Colorbond Steel | $85 – $160 | 30–45 years |
Terracotta Tiles | $120 – $200 | 50+ years |
Slate | $200 – $300+ | 75–100 years |
Concrete Tiles | $100 – $180 | 30–50 years |
Note: These are rough estimates and can change depending on your location and roof type.
If you want something tough that lasts through storms and hot summers, Colorbond roofing is a top choice in Australia. It costs a bit more upfront, but it’s durable, fire-resistant, and doesn’t need much upkeep.
What Does a Full Roof Replacement Include?
When you hear “roof replacement,” it’s more than just slapping on new tiles. Here’s what a full job usually includes:
- Inspection and quote
- Removing the old roofing
- Checking the structure underneath
- Replacing battens or adding insulation (if needed)
- Installing new roofing material
- Sealing, flashing, and waterproofing
- Cleanup and disposal of old materials
Each of those steps adds to the cost to install a new roof, so it’s smart to get a detailed quote from a trusted roofing company. If you’re unsure where to start, we recommend checking out Smile Roofing’s trusted services for a clear and upfront experience.

How to Save Money Without Cutting Corners
Let’s be real—replacing a roof isn’t cheap. But there are smart ways to stretch your dollar:
- Compare quotes – Don’t just go with the first one. Get at least 2–3.
- Pick long-lasting materials – Spending a bit more now can save heaps later.
- Bundle repairs – Need gutters replaced too? Doing it all at once may reduce labour costs.
- Plan during off-season – Roofers are less busy in winter, and you might score a discount.

Home Type | Roof Size (m²) | Estimated Cost Range |
Small Home | 100–150 | $8,000 – $14,000 |
Medium Home | 150–220 | $13,000 – $19,000 |
Large Home | 220–300+ | $18,000 – $28,000+ |

How Long Does It Take to Install a New Roof?
Most standard homes can get a full roof replacement done in 2 to 5 days—weather permitting. For bigger jobs or specialty materials like slate or terracotta tiles, it might take up to a week or two.
Final Thoughts: Is It Worth the Investment?
Absolutely. Your roof protects everything underneath it—your family, your furniture, your peace of mind. Skimping on it now can cost you a lot more later.
Sure, the cost to install a new roof might seem steep at first. But with the right materials and a skilled team, you’ll have decades of protection, a boost in home value, and even better street appeal.
