What a new roof costs by home size
$15,000 – $25,000
Standard 3-bedroom home, tile-to-Colorbond conversion, easy access, standard pitch. The most common Adelaide replacement.
$25,000 – $35,000
More roof area, complex rooflines, hips and valleys, or a higher pitch needing more labour and edge protection.
$35,000 – $45,000+
Two-storey access, full scaffold, premium terracotta tile-for-tile, or heritage detailing and structural upgrades.
A range is useful. Your actual number is better.

Colorbond vs tile vs terracotta
Supply-and-install of the roof material only. Add removal of the old roof, scaffold and any structural work to reach the full per-m² figure (often $90 to $150/m² all-in).
Colorbond steel
$50 – $90 / m²
Lightest, fastest to install, full BlueScope warranty. Best value for most replacements.
Concrete tile
$40 – $80 / m²
Heavier, traditional look. Cheaper per tile but slower and heavier to install.
Terracotta tile
$80 – $120+ / m²
Premium, long-life, heritage look. The most expensive option to replace like-for-like.
What drives a roof replacement quote up or down
- Roof area — measured in square metres, the single biggest factor
- Material — Colorbond, concrete tile or terracotta
- Pitch and complexity — hips, valleys, dormers and steep pitch add labour
- Access — two-storey or tight sites need scaffold or edge protection
- Removal and disposal of the existing roof material
- Sarking and batten upgrades once the old roof is off
- Insulation blanket and roof ventilation (we include these)
- New flashings, valleys, gutters and downpipes
Every Pro Roof and Gutter replacement includes a free 50mm insulation blanket, a spinning vent, and all new flashings — items some cheaper quotes leave out.
Cheap quote red flags
- · No line for removal and disposal of the old roof
- · “Colorbond-style” or generic colour-coated steel, not genuine BlueScope
- · Old battens and sarking reused instead of upgraded
- · No insulation blanket included
- · No manufacturer warranty registered to you in writing
- · A per-m² price with no site visit

Frequently asked questions
Most full roof replacements in Adelaide land between $15,000 and $30,000 for a standard single-storey home, and $30,000 to $45,000+ for larger, two-storey or tile-for-tile jobs. The biggest variables are roof area, the material you choose (Colorbond is generally cheaper to install than new terracotta), pitch, access, and how much sarking, batten or structural work is needed once the old roof comes off.
As a rough guide for a like-for-like supply-and-install: Colorbond steel runs about $50 to $90 per square metre, concrete tile about $40 to $80, and terracotta tile $80 to $120+. Those figures don't include removal of the old roof, scaffolding, sarking upgrades or structural repairs, which is why a real quote after a site visit is always more accurate than a per-metre estimate.
Usually yes. A tile-to-Colorbond conversion is often cheaper than a tile-for-tile replacement because Colorbond is lighter, faster to install, and you're not paying for premium terracotta. You also get a lighter roof load, a manufacturer warranty, and the option of a free insulation blanket. The trade-off is the look — some heritage homes suit tile better.
If the roof is structurally sound and just tired-looking, restoring it is far better value than a full replacement, and our roof restoration cost guide has the current Adelaide ranges. Replacement is the right call when the roof is past saving: sagging timbers, repeated leaks in different spots, asbestos substrate, or tiles so brittle that a coating won't hold. A free on-site quote tells you which side of that line you're on.
Yes. A new Colorbond or tile roof is one of the few renovations that improves both the look and the insurability of a home. Valuers and buyers both treat a roof with remaining life and a transferable warranty as a genuine asset, and it removes the single biggest 'unknown cost' a buyer worries about.
Be careful with any quote well under the ranges above. Cheap quotes often skip the sarking upgrade, reuse old battens, leave out the insulation blanket, use generic colour-coated steel instead of genuine BlueScope Colorbond, or quietly exclude removal and disposal of the old roof. Always get the scope in writing and check it's genuine Colorbond with the manufacturer warranty.
