Cost of Roof Replacement in Adelaide — Full 2026 Pricing Breakdown

The big-picture number

For a typical Adelaide single-storey home with 130–170sqm of roof, expect $15,000–$28,000 for a Colorbond re-roof and $19,000–$32,000 for a terracotta tile re-roof. Double-storey costs significantly more per square metre because of access — scaffolding adds $2,000–$5,000 alone.

Cost by material

Colorbond Trimdek (the volume choice): $80–$120 per sqm installed, including strip and disposal. Custom Orb (heritage corrugated): adds $5–$15 per sqm. Spandek (architectural concealed-fix): $130–$190 per sqm. Concrete tile: $100–$140 per sqm. Terracotta tile: $120–$170 per sqm. The premium materials cost more not just for the material itself but for the slower install (concealed-fix profiles take longer).

Cost drivers beyond material

Roof access is the biggest hidden cost. A steep two-storey Federation house in the inner east costs more per square metre than a low-pitch ranch in Modbury. Asbestos sarking discovered during the strip is the most common surprise — adds $80–$150 per sqm in licensed removal. Structural battens that need replacement add $25–$45 per sqm. Heritage planning rules (council-mandated material match) can lock you into the more expensive option.

What’s included in a quality quote

Strip and disposal of existing roof. New sarking. New or salvaged battens. Manufacturer-recommended fasteners for the roofing product. New ridge cap bedding (flexipoint over cement). Valley iron replacement where required. Gutter integration if existing gutters stay. Final clean and waste removal. Written workmanship terms plus the manufacturer’s product warranty (BlueScope warranties on COLORBOND® steel run up to 36 years for some products and sites).

What’s not included (watch for these)

Asbestos removal (separate, licensed cost). Structural rebuild of rotted rafters. Solar panel removal and re-install (typically $850–$1,800). Skylight replacement if existing units are at end-of-life. Council fees if your property is on heritage overlay. Planning consent if the colour change is regulated.

How to compare quotes fairly

Look at the per-square-metre installed cost rather than the headline number. A quote in the $24,000–$26,000 band on a 200sqm roof ($120–$130/sqm) and a quote in the $27,000–$29,000 band on a 180sqm roof ($150–$160/sqm) are wildly different. Confirm the manufacturer warranty registration is included. Confirm the asbestos provision — what happens if asbestos is found mid-strip? Some quotes increase significantly mid-job; others have a written variation clause that locks the rate.
