Roof Replacements · Commercial & Residential
Roof replacement in Sydney — tile, Colorbond & metal.
When a roof is past restoring, we strip and rebuild it properly. Colorbond, tile or metal — for homes and commercial buildings across Greater Sydney.
Overview
What this service covers.
If your roof has had repeated repairs, sagging timbers, widespread rust or end-of-life tiles, replacement is the honest call. We project-manage the whole job — strip-out, new sarking, new battens or purlins where needed, then the new roof in your chosen material.
- Tile-to-tile replacement (terracotta, concrete)
- Tile-to-Colorbond conversion
- Existing Colorbond / metal roof replacement
- New sarking & battens, valley irons, flashings, ridge capping
- Gutter replacement bundled in (recommended at the same time)
- Commercial re-roofs — strata buildings, warehouses, offices

Bondi
Postcode 2026Bondi rooftops cop one of Sydney's harshest weather mixes — salt air off the Tasman, sustained UV, and sudden southerly busters.
Roofing in BondiChatswood
Postcode 2067Chatswood's mix of mid-century brick homes, 1990s townhouses and recent high-density apartments needs different roofing answers across the same postcode.
Roofing in ChatswoodCronulla
Postcode 2230Cronulla's beachfront exposure makes marine-spec roofing the default — the same salt-corrosion logic as Bondi runs the full length of the Shire coast.
Roofing in CronullaHornsby
Postcode 2077Hornsby and the upper North Shore sit under heavy tree canopy — gutter loading and leaf-guard work dominate the call-outs.
Roofing in HornsbyLiverpool
Postcode 2170Liverpool and the broader South West has a fast-growing mix of established post-war housing, 80s–90s estates and new-build estates — and a steady stream of builder-spec warranty work.
Roofing in LiverpoolManly
Postcode 2095Manly's peninsula geography means salt air across most of the suburb — and a housing stock that runs from heritage Federation through to designer architectural builds.
Roofing in ManlyMosman
Postcode 2088Mosman's housing stock skews high-value heritage — Federation, Edwardian and Inter-War with tile and slate roofing that needs specialist knowledge.
Roofing in MosmanParramatta
Postcode 2150Parramatta is one of Sydney's densest commercial centres — our work skews to commercial buildings, strata and large multi-residential.
Roofing in ParramattaPenrith
Postcode 2750Penrith and the foothills carry the hottest summers in metro Sydney — material choice matters more here than almost anywhere else.
Roofing in PenrithSutherland
Postcode 2232Sutherland proper — inland Shire — has a different material logic to coastal Cronulla. Tile dominates and tree canopy drives gutter work.

Still have a question?How much does a new roof cost in Sydney?
A new Colorbond roof on a typical 3-bedroom Sydney home costs between AUD 9,000 and 20,000 depending on size, profile, pitch and whether the existing roof is removed. Tile-to-tile $12,000–22,000. Tile-to-Colorbond $14,000–25,000. Confirmed in a free written quote.
How long does a replacement take?
Most residential replacements take 3–7 working days from strip to clean-up, weather depending. We schedule strip-out in fine weather windows and tarp overnight.
What warranty do I get?
A written 10-year workmanship warranty from us, plus the manufacturer warranty on materials (BlueScope Colorbond up to 36 years, tile manufacturers 50+ years).
Do you handle commercial re-roofs?
Yes — strata buildings, warehouses, schools, and commercial offices. Different sales cycle (architects, project managers, strata committees) but the same trades and standards.
