How much does a roof replacement cost in Brisbane?
A full roof replacement in Brisbane costs $10,000–$25,000 for a single-storey home and $15,000–$40,000 for a two-storey, with most standard homes landing near $16,000. Measured by area, expect $80–$180/m² for Colorbond and $100–$220/m² for tiles, supplied and installed. GST included — verified July 2026.

Roof replacement cost by home size in Brisbane
Total replacement cost tracks roof area and storey height more than anything else. A second storey adds scaffolding, slower material handling and a longer job, which is why the two-storey band starts where the single-storey band is already well underway.
| Home type | Low | Typical | High |
|---|---|---|---|
| Full roof replacement (single-storey) | $10,000 | $16,000 | $25,000 |
| Full roof replacement (two-storey) | $15,000 | $25,000 | $40,000 |

Cost per square metre: Colorbond vs tiles
Most Brisbane quotes are built up from a rate per square metre of roof area, then adjusted for access and the condition of what is underneath. Colorbond is the cheaper rate of the two and the lighter material; tiles cost more per metre and put more load on the frame.
| Re-roof type | Low | Typical | High |
|---|---|---|---|
| Re-roofing — Colorbond (per m²) | $80 | $120 | $180 |
| Re-roofing — tiles (per m²) | $100 | $150 | $220 |
On a 150 m² roof — a common single-storey Brisbane footprint — that works out to roughly $18,000 in Colorbond at the typical rate, against about $22,500 in tiles. Both sit inside the single-storey replacement band above, which is the sanity check worth doing on any quote you receive: rate per square metre times your roof area should land near the total.

Tile-to-Colorbond conversions
Converting a tiled roof to Colorbond is one of the most common roofing projects in Brisbane, and it prices differently to a like-for-like re-roof. You are paying to strip and dispose of the old tiles, check and often replace battens, and re-sheet — so a conversion typically runs around 30% above a straight replacement in the same material.
The trade-off is weight and weather. Tiles are heavier, and a conversion takes significant load off the frame; Colorbond sheds Brisbane’s summer downpours quickly and handles storm season well. The catch is that the saving does not show up on day one — it shows up in the decades of low maintenance that follow.
What drives the price in Brisbane
Two homes with identical floor plans can be quoted thousands apart. These are the factors that move the number most:
- Roof area and pitch — area sets the base cost; a steep pitch slows the job and adds safety requirements.
- Access — high-set Queenslanders, tight side setbacks and limited street frontage all add time and equipment before a single sheet goes on.
- Removal and disposal — stripping an existing roof and carting it away is real cost, and it is the single biggest gap between a re-roof quote and a conversion quote.
- What is underneath — rotten or undersized battens, sagging structure or failed sarking are found once the old roof is off. Good quotes state what happens if this turns up.
- Material grade — exposure matters near the bay and in storm-prone pockets, and the specification changes accordingly.
- Character and heritage overlays — parts of Brisbane restrict changes to a roof’s appearance from the street, which can rule out a straight material swap.
Repair, restore, or replace?
Replacement is the most expensive answer to a roof problem, and it is not always the right one. The rough decision line:
- Repair — a minor leak runs $250–$800, and replacing cracked tiles $300–$1,000. Worth it where the structure is sound and the problem is localised.
- Restore — a clean, re-bed and re-point, then a coat: roof painting on a single-storey home runs $2,500–$6,000. This buys years, not decades, and only where the underlying roof is still serviceable.
- Replace — once repairs are recurring, battens are going, or more than a small share of the roof is failing, replacement stops being the expensive option and starts being the cheaper one.
If you are unsure which side of the line you are on, a roof inspection and report costs $200–$500 and gives you something to quote against.
Budget for the ancillaries
Replacement is the moment when everything attached to the roof is accessible and cheap to do — and expensive to come back for later. The usual add-ons:
| Item | Low | Typical | High |
|---|---|---|---|
| Gutter replacement (per m) | $40 | $70 | $110 |
| Downpipe replacement (per m) | $35 | $60 | $90 |
| Ridge capping repair | $400 | $750 | $1,200 |
| Skylight installation | $1,500 | $2,500 | $4,000 |
