What this calculator estimates

This calculator gives you a line-by-line installed 2026 Australian price for a tiled roof — whether you are choosing concrete, terracotta, natural slate, or synthetic composite. The structure mirrors how ARC-member and Master Builders Association roofers quote real jobs:

  • Tile material — concrete, terracotta, natural slate, or synthetic composite (supply and fix)
  • Strip-out — removing the existing covering down to the rafters
  • Sarking — anticondensation foil-laminate membrane (AS 4200.1)
  • Battens — AS 2050 treated softwood batten and counter-batten
  • Ridge — mortared, flexi-point, or dry ridge per linear ft
  • Valley flashing — Colorbond, zinc, or copper per linear ft
  • Structural reinforcement — rafter doubling for heavier tile loads
  • Council building consent, skip disposal, and weekend premium

A A$620 minimum call-out fee applies across most Australian metros — even a small tile repair requires a two-person crew with scaffolding, harness, and skip hire.

How to use it

  1. Enter roof area in m². A typical 200 m² brick-veneer house has 220 to 280 m² of roof slope area depending on pitch.
  2. Pick tile material — concrete is the budget choice, terracotta the heritage and coastal favourite, slate the premium, composite the modern hybrid.
  3. Set scope — spot repair (15% of area), partial replace (45%), or full re-tile (100%).
  4. Set storey count — single-storey 1.0x, two-storey 1.2x, three-storey 1.45x.
  5. Set access difficulty — drive-up 1.0x, rear/side 1.1x, EWP/lift needed 1.3x.
  6. Enter ridge cap, Colorbond valley, and rafter reinforcement in linear feet.
  7. Toggle strip-out, sarking, batten, council consent, skip disposal, weekend premium and any extra labour hours.

Cost drivers

Tile material and origin. Concrete tile manufactured locally by BMI Boral (Wollongong, Sydney, Brisbane plants) or CSR Monier (Plumpton, Beresfield, Rocklea plants) ships short distances and is the budget choice. Terracotta from Monier Wunderlich (Plumpton plant) or imported La Escandella ships further and carries a 30 to 50 percent material premium.

Wind region and BAL rating. Wind Region B (most of southeast Australia) is standard. Wind Region C (cyclonic — NQLD coast, NT, northern WA) requires every tile mechanically fastened with Type 17 screws or storm clips, adding A$15 to A$25 per m². BAL-19 and above (bushfire-prone) require ember-mesh on all roof penetrations and gutter guards.

Pitch and roof complexity. Most Australian tile roofs are 22.5° to 35° (about 5/12 to 9/12). Above 35°, fall protection adds 25 to 40 percent labour. Below 15° tile is unsuitable; the only option is membrane or metal.

Structural reinforcement. AS 1170.1 dead load increases over 10 percent require structural sign-off. Switching from Colorbond to concrete tile triples dead load. A consulting engineer’s report runs A$450 to A$1,200. Rafter doubling at A$75 to A$120 per linear m can add A$2,500 to A$8,000 to a typical project.

Sarking and ventilation. NCC 2022 Part 3.12.1 makes anticon sarking mandatory under tile in climate zones 1 through 5. Heavy-duty sarking for cyclonic regions is A$14 to A$20 per m². Roof space ventilation under AS 4859.1 typically requires soffit + ridge or gable vents — allow A$300 to A$800 for the ventilation package.

Strip-out and disposal. Concrete tile weighs about 55 kg/m². Skip hire for a 200 m² strip-out runs A$700 to A$1,200. Terracotta is often recovered for resale, offsetting A$8 to A$14 per m² of disposal cost.

Diagnostic step-by-step before quoting

  1. Have a structural engineer evaluate the framing — at A$450 to A$1,200 the report confirms whether reinforcement is needed.
  2. Check council overlays — heritage, bushfire (BAL), flood, and wind region overlays dictate tile type and fastening.
  3. Inspect the existing roof space — sarking condition, batten condition, rafter condition, and ceiling staining tell you scope.
  4. Get three ARC-member or MBA-registered bids that itemize tile, sarking, batten, ridge, valley, structural, scaffold, council consent, and skip as separate line items.
  5. Confirm warranty terms — Monier and Boral concrete tile warranty is 50 years material, Monier Wunderlich terracotta is 50 to 75 years. Installer workmanship under ARC is 7 years minimum.

Frequently asked questions

How much does a tile roof cost in 2026 in Australia?
Most Australian homeowners pay A$95 to A$280 per m² installed for a tiled roof in 2026, all-in with strip-out, anticondensation sarking, AS 2050 treated battens, mortared or flexi-point ridge, and Colorbond valley. A 200 m² typical brick-veneer house in Sydney, Melbourne, or Brisbane with Monier or Bristile concrete tile lands around A$22,000 to A$32,000. Terracotta tile (Monier Wunderlich, La Escandella) runs A$32,000 to A$48,000 in the same size, and natural slate is A$48,000 to A$80,000. Source: 2026 ARC Member Survey; Master Builders Australia Roofing Cost Index 2026; hipages Q1 2026 quoted jobs across NSW, VIC, QLD, WA, and SA.
Concrete versus terracotta tile — which is better in Australia?
Concrete tile (Monier Wunderlich Madison, Bristile Prestige, BMI Boral Roofing) is consistently 35 to 50 percent cheaper installed than terracotta tile in 2026 Australian pricing. Concrete tile costs A$95 to A$140 per m² installed; terracotta A$160 to A$240 per m² installed. Lifespan favours terracotta (75 to 100 years) over concrete (50 to 75 years). In coastal salt-spray zones (within 5 km of the coast), terracotta and glazed clay tile resist surface degradation far better than concrete — long-term lifecycle costs often favour terracotta in coastal areas of NSW, QLD, and WA.
What pitch is needed for tile in Australia?
AS 2050:2018 sets the minimum pitch for concrete and terracotta tile at 15° (about 2.5/12). Below 15°, tiles require anticondensation sarking with a self-adhered cap sheet at the eaves and valleys, plus mechanical fastening of every tile (typically with Type 17 timber screws or storm-clip fasteners). Above 35° pitch and in cyclonic zones (Wind Region C and D — coastal NQLD, NT, and northern WA), every tile must be mechanically fastened to comply with AS 1170.2 wind load requirements. Source: AS 2050:2018; AS 1170.2:2021; AS 4055:2021.
Do I need a structural engineer for re-tiling in Australia?
Yes if changing covering type that increases dead load by more than 10 percent under AS 1170.1. Concrete tile is about 55 kg per m² installed; terracotta about 48 kg per m². Switching from Colorbond (about 5 kg/m²) to concrete tile triples the dead load and requires structural sign-off. A consulting engineer's report runs A$450 to A$1,200. Rafter sistering or doubling at A$75 to A$120 per linear m is typical when needed. Council building consent will require structural calculations on file before approving any covering change. Source: AS 1170.1:2002 (R2016); NCC 2022 Volume Two Part 3.5.
What is sarking and is it required under tile?
Sarking is a reflective foil-laminate anticondensation membrane (anticon) installed beneath the battens and tiles, providing thermal reflection, water resistance, and condensation control. AS/NZS 4859.1:2018 specifies the reflective and emissivity requirements; AS 4200.1:2017 specifies the membrane class. The NCC 2022 Part 3.12.1 makes sarking mandatory under all new tile roofs in climate zones 1 through 5 (most of Australia). Allow A$8 to A$12 per m² for medium-duty anticon sarking by Bradford Thermoseal, CSR Bradford, or Knauf. Heavy-duty cyclone-rated sarking (Wind Region C/D) is A$14 to A$20 per m². Source: AS/NZS 4859.1:2018; AS 4200.1:2017; NCC 2022 Vol Two Part 3.12.1.
Bushfire BAL rating — does it affect tile choice?
Yes. AS 3959:2018 requires bushfire-attack-level (BAL) compliance for any reroof in a designated bushfire-prone area. Concrete and terracotta tile are inherently non-combustible and meet up to BAL-FZ (Flame Zone, the highest rating) without restrictions. Synthetic composite tiles must be specifically rated to AS 3959 — some are not suitable above BAL-29. Above BAL-19 you also need ember-mesh covers on roof penetrations and gutter ember guards. Allow A$300 to A$800 for the ember-mesh and gutter guard package. Source: AS 3959:2018.
Do I need a council building permit for re-tiling?
Like-for-like re-tiling (concrete-to-concrete, terracotta-to-terracotta) is typically exempt development and does not require a permit. Changing tile type or going from metal to tile or vice-versa typically requires either a Complying Development Certificate (CDC) or Development Application (DA) depending on the council and overlay (heritage, bushfire, flood). Allow A$400 to A$1,200 for CDC fees plus a registered building practitioner to sign off the structural and weatherproofing aspects.
How does Boral compare to Monier for concrete tile?
Boral (now BMI Boral Roofing after the 2021 sale) and Monier (now CSR Monier) are the two largest concrete tile manufacturers in Australia, with comparable quality and price points. Boral ranges include the popular Cambridge, Macquarie, and Striata profiles. Monier ranges include the Madison, Horizon, and Atura profiles. Pick by colour and profile availability in your area — most major metros have both in stock. Bristile (now Brikmakers Roofing) is the third major brand and is regionally strong in WA and SA.
