Roof Replacement Cost in Adelaide (2026 Guide)

A full roof replacement on an average Adelaide home of 150 to 200 square metres generally costs $15,000 to $35,000. The final figure depends on the material, the roof's complexity, and whether scaffolding is needed.

Colorbond is usually quoted at $60 to $100 per square metre installed. Tile re-roofing runs higher, often $80 to $110 per square metre, and costs roughly 10 to 15 percent more than the equivalent Colorbond job.

The most common replacement in Adelaide is a tile-to-Colorbond conversion. Colorbond is lighter, which can simplify the roof structure, and it needs less maintenance than tile over its life.

Get at least three quotes and check each one lists removal and disposal of the old roof, new insulation or sarking, and the gutters and flashing. A cheap quote that leaves those out is not comparing like for like.
