Metal & Colorbond roof replacement cost in Sydney 2026
In Sydney, a metal re-roof in Colorbond runs $95–$210/m² installed — about $10,000–$20,000 for a like-for-like replacement on a typical home, or $20,000–$35,000 to convert from tile. Coastal suburbs need marine-grade steel, which lifts the rate but is the difference between a 12-year roof and a 30-year one.

Quick answer — metal reroof costs in Sydney 2026
Metal roofing is quoted per square metre installed. Here's the 2026 Sydney picture for a typical home:
| Job | Sydney cost | Notes |
|---|---|---|
| Colorbond (Ultra) installed | $95–$210/m² | Materials + labour; profile and grade move the rate |
| Like-for-like Colorbond reroof | $10,000–$20,000 | Sound battens and structure; 2–3 days on a typical home |
| Tile-to-Colorbond conversion | $20,000–$35,000 | Adds tile removal/disposal and possible batten work |
| Marine-grade upgrade (Ultra/Coastline) | +$25–$45/m² | Needed in coastal and harbour salt zones |
Why so many Sydney roofs go metal
Colorbond is roughly 70% lighter than tile, which eases the load on an ageing timber roof structure — a real advantage on Federation and Edwardian homes. It installs fast (two to three days on a standard home), carries a 25-year BlueScope warranty when fitted by a licensed roofer, suits bushfire-prone and coastal sites with the right grade, and gives the clean modern lines a lot of Sydney renovators want.

Colorbond vs Zincalume vs standing seam
Colorbond is pre-painted steel in a full colour range — the default choice for most Sydney homes. Zincalume is the unpainted silver version: cheaper, durable, but limited on looks. Standing seam (concealed-fix architectural roofing) gives a premium, clean-lined finish and costs more per square metre. Profile matters too — corrugated, Trimdek and Klip-Lok all price slightly differently.
Salt air: get the right grade
Standard Colorbond near the surf or in harbourside salt zones can void its warranty within about 12 years. Suburbs like Bondi, Bronte, Manly, the eastern beaches and harbour-edge homes need marine-grade Colorbond Ultra or Coastline, which adds roughly $25–$45/m² but extends warranty coverage past 30 years. It's not an upsell on the coast — it's the difference between one reroof and two.
What drives the price
- Like-for-like vs conversion — converting from tile adds removal and disposal ($30–$50/m²) and sometimes new battens.
- Roof size, pitch & access — two-storey and steep roofs need more scaffolding and labour.
- Steel grade & profile — marine-grade and architectural profiles cost more.
- Gutters, fascia & sarking — usually replaced while the roof is open.
- Asbestos — if the old roof is asbestos, licensed removal changes the job entirely (see asbestos roof removal).
