Costs, Price Factors and 2026 Rules
What drives the price of a new roof or new cladding, how the main materials compare, and the licensing, insurance, approval and safety rules in each state.
roof replacement cost per square metre
A roofing quote is only comparable once you know the roof area, the material, what is being removed and what your state's rules require. These guides show the arithmetic, the licence and insurance thresholds, and where to complain if things go wrong.

How a pre-painted steel roof compares with concrete and terracotta tiles in Australia on price per square metre, structure, heat, noise, bushfire, wind and maintenance.
Turn your roof area and roofing option into an illustrative low and high price range, plus fixed costs such as edge protection and waste.
Estimate an illustrative price range for replacing or adding external wall cladding on a house, by wall area and cladding type.
Check the maximum deposit a contractor can lawfully ask for under your state's cap, and how much is left for progress payments.
See the monthly repayment, total interest and total cost of borrowing for a new roof with a personal loan or similar finance.
Tick off the checks that matter from first inspection to final payment on a re-roof or re-cladding job.
| Option | How it works | Good for | Watch out for |
|---|---|---|---|
| Tile roof restoration | Clean the tiles, replace broken ones, re-bed or re-point ridge capping, then often apply a coating | Concrete or terracotta roofs with sound tiles, battens and structure | Does not fix rotten battens, failed sarking or porous tiles; coatings are cosmetic and need recoating |
| Metal re-sheet over existing metal | Remove old sheets, check and refix battens, install new sheets, flashings and ridge | Rusted or leaking steel roofs on a sound frame | Gutters, valleys and flashings are often extra; fixings must suit the wind classification |
| Tile to steel (Colorbond-style) | Remove tiles and possibly battens, add sarking or insulation blanket, install pre-painted steel sheets | Lighter roof load, fewer joints, suits low pitches and bushfire or cyclone upgrades | Tie-downs may need upgrading; a heritage overlay may require approval to change the material |
| Concrete tile re-roof | Strip and replace with new concrete tiles on new or existing battens | Keeping a tiled look at lower cost than terracotta | Heavy: the frame must carry the load; tiles can be brittle with age |
It depends on the material, what is removed and how complex the roof is. On this site we use illustrative ranges such as $90–$160 per m² for tile to steel and $25–$60 per m² for a tile restoration, plus fixed costs for edge protection and waste. Measure your roof surface area and run the re-roof cost estimator, then compare with real written quotes.
Re-roofing from tile to pre-painted steel is often cheaper than a new terracotta roof and in a similar range to new concrete tiles, but the answer depends on battens, sarking, gutters and structural work. See tile versus Colorbond for a full comparison.
Usually yes above a value threshold. For example, Queensland requires a QBCC licence for most building work over $3,300 and NSW requires a licence for residential building work over $5,000. Victoria and Western Australia have their own thresholds, and metal roofing and stormwater work in Victoria is plumbing work. See the licence threshold guide.
Often, if the job is above your state's threshold: over $20,000 in NSW, over $3,300 in Queensland for roof work, over $20,000 in Victoria for Home Warranty insurance on contracts from 1 July 2026, and over $20,000 for permit work in WA. The contractor must give you the certificate before taking payment. See home warranty insurance thresholds.
In NSW the cap is 10%. In Victoria it is 5% for contracts of $20,000 or more and 10% below that. In Queensland it is 5% for contracts of $20,000 or more. In WA it is 6.5% for contracts under the Home Building Contracts Act. Use the deposit limit check.
Home building insurance generally covers sudden storm damage, but not wear and tear, rust, gradual deterioration or poor maintenance. Insurers often pay to repair the damaged section rather than replace the whole roof. See storm damage versus wear and tear.
Removing more than 10 m² of non-friable asbestos requires a Class B licence, and any friable asbestos requires a Class A licence. A whole roof is far more than 10 m², so a licensed removalist is needed. See the asbestos roof guide.
Raise it in writing with the contractor first, then contact your state building regulator or fair trading body, for example Building Commission NSW, the Building and Plumbing Commission in Victoria or the QBCC in Queensland. See where to get help.
