Real 2026 Sydney restoration prices, what moves the number, and how to tell a fair quote from a cheap one that won't last.
In Sydney right now, roof restoration runs roughly $30 to $45 per square metre — so a small single-storey home (120–150m²) usually lands around $4,500–$7,000, a medium home (160–220m²) around $6,500–$10,000, and a large or two-storey roof $8,000–$15,000+. A cleaner, seal-and-recoat job on a sound roof can start closer to $3,000; a big roof needing a lot of re-bedding heads toward the top.
That range is wide for real reasons, not guesswork. Size is the obvious one. Pitch matters — a steep or two-storey roof is slower and needs more safety gear. Terracotta costs more to work than concrete. And the state of the ridge capping is the quiet cost driver: if every cap needs re-bedding and re-pointing, that's real labour. Two identical-sized roofs can differ by $3,000–$4,500 on condition alone.
Be wary of a quote that's a lot cheaper than the rest. Restoration is one of those jobs where the corners you can't see are the ones that get cut — thin single-coat membrane instead of primer-plus-two, rigid pointing that cracks off in a year, a pressure-clean that skips the moss treatment so it grows straight back.
We quote after the free documented inspection, so the number is based on your actual roof, not a phone estimate. And if the roof's too far gone to restore, we'll say so rather than take your money for a coat of paint over a problem.
Figures are general guidance for Sydney and vary with your roof. The only accurate number is a documented on-site quote — which is free.
