How much does roofing cost in Sydney?

Roof replacement cost in Sydney (2026)

The roof replacement cost in Sydney runs $17,250–$46,000 for a typical full re-roof, depending on roof size, material, pitch, and access. Colorbond is usually the most cost-effective option; tile and slate sit at the higher end. Here is what a full roof replacement costs across Sydney in 2026.

A roof replacement in Sydney usually takes 3–7 days for Colorbond and 5–10 days for tile, weather permitting. Two-storey homes add scaffolding ($2,000–$6,000) and asbestos removal adds $30–$60/m².

Roof replacement cost by roof size and material (Sydney 2026)

Roof size is the biggest single driver of replacement cost. Here's the supply-and-install total for common Sydney roof areas by material (labour + materials, GST incl.).

Based on Sydney rates of $130–$170/m² Colorbond, $120–$170/m² concrete tile, $150–$230/m² terracotta, $250–$400/m² slate. Roof area is typically 1.3–1.5× floor area.

What's included in a Sydney roof replacement price

A replacement quote isn't just new tiles or sheets — it covers the whole job of getting the old roof off and a new one safely on. Here's where the money goes:

• Stripping and disposing of the old roof — labour to remove the existing roof plus tip fees on the waste.
• Checking and replacing battens and sarking — timber or metal battens and the reflective/waterproof sarking layer underneath, renewed where they've perished.
• New material supply — the Colorbond sheeting or tiles themselves, the single biggest line item.
• Install and fixing — laying, screwing or bedding the new roof, the main labour component.
• Flashing, ridge capping and re-pointing — sealing valleys, penetrations and ridge lines so the new roof is watertight.
• Scaffolding and access — safe working platforms; single-storey is cheap, two-storey adds $2,000–$6,000.
• Waste disposal and final cleanup — skip hire, magnet sweep for stray screws, and site tidy.

As a rough split, expect materials ~40–50%, labour ~35–45%, and removal, disposal and scaffolding ~10–20% of the total. Two big swing factors sit on top: two-storey scaffolding (the $2,000–$6,000 above) and, on older fibro roofs, licensed asbestos removal at $30–$60/m². Choosing a lighter, faster metal roof over tile also shifts the mix — see how tile and Colorbond compare.

Repair, restore or replace the roof — where the money makes sense

If the roof is structurally sound with isolated leaks or a handful of cracked tiles, repairs or a restoration are usually the better spend. But once rust, cracked valleys or sagging battens show up across multiple sections, patching stops paying for itself — and when repair quotes start stacking into the thousands, replacement is often the smarter long-term call. A full roof replacement resets the whole system in one go: sheeting or tiles, sarking, flashings and fixings, typically with a fresh workmanship warranty behind it.

What you'll pay to replace a roof in Sydney — three common jobs

For a single-storey Sydney home, a full roof replacement runs $11,500–$28,750 in 2026, with most jobs landing around $18,400. Two-storey homes and terraces sit higher at $17,250–$46,000 (typically $28,750) once scaffolding and access are priced in. On a per-square-metre basis, expect $92–$207/sqm to replace roof sheeting with new Colorbond, or $115–$253/sqm for a tile re-roof — so a standard 150 sqm roof in Colorbond comes out near $20,700 at typical rates.

How Sydney roofing prices are quoted

Most Sydney roofing prices come through as a fixed supply-and-install figure rather than an hourly rate, built from your roof area, pitch and material. What pushes a quote to the top of the range: two-storey access, steep pitches needing extra safety rail, heritage overlays, and old asbestos sheeting that has to be removed by a licensed crew before the new roof goes on. Sydney roofing prices moved about 5% over the past year, so a quote more than a few months old is worth re-checking before you sign.
