Pricing guide / updated 2026
What does a new roof cost in Christchurch?
Straight numbers from a roofer, not a lead-generation site. What drives the price of a reroof in Canterbury, realistic ranges for 2026, and how to compare quotes without getting caught.
The honest headline numbers
Every roof is different, so treat these as realistic Canterbury ranges rather than a price list. For a typical single-storey 150 to 200 m² home:
| Item | Typical range (incl. labour) |
|---|---|
| Long-run steel roofing, installed | from ~$100 + GST per m² |
| Full house reroof (150 to 200 m²) | $18,000 to $35,000 |
| Scaffolding & edge protection | $2,000 to $5,000 |
| Asbestos roof removal (licensed) | $65 to $85 + GST per m² |
| Insulation top-up while roof is off | $1,500 to $4,000 |
| Spouting & downpipe replacement | $2,500 to $7,000 |
Ranges reflect typical Canterbury residential jobs as at 2026 and include labour. Your roof may sit outside them. That is what the free quote is for.
What moves the number
Size and pitch. Area drives material; pitch drives labour and safety setup. A steep roof is slower and needs more protection than a walkable one.
Access. Two-storey homes, tight sites, and anything a truck can't get near all add scaffold and handling time.
What's coming off. Heavy concrete tile costs more to strip and dispose of than iron; asbestos cement adds licensed removal, monitoring and certification.
What we find underneath. Rotten purlins, borer-ridden sarking and rusted valleys can't be seen until the roof is open. We include a realistic allowance and price the common discoveries up front, so surprises are the exception.
Details and penetrations. Chimneys, skylights, flues, solar mounts and box gutters each need flashing work. A roof with a dozen penetrations costs more than a clean gable of the same size.
Comparing quotes without getting caught
- Same scope? Scaffolding, disposal, underlay, flashings and GST should all be explicit in every quote you compare.
- Allowances stated? A quote with no purlin/timber allowance becomes a variation the day the roof opens.
- Who does the work? Ask whether the person quoting will be on the roof, or whether the job is sold and subcontracted.
- Licensed and insured? LBP number and public liability insurance are the minimum. Ask for both.
- References you can drive past? We give addresses of completed roofs. Paint colours and profiles look different in real light than on a swatch.

Cost questions
How much does a new roof cost in Christchurch in 2026?
For a typical 150-200 m² Canterbury home, a full long-run steel reroof usually lands between $18,000 and $35,000 including GST and scaffolding. Installed long-run steel typically starts around $100 + GST per square metre, with the final figure driven by roof size, pitch, access, the material coming off and any structural repairs.
What adds the most to a reroofing quote?
The big variables are scaffolding and edge protection (roughly $2,000 to $5,000 on most homes), asbestos removal where the old roof contains it (roughly $65 to $85 + GST per square metre), replacing rotten purlins or sarking discovered during the strip, and complexity: steep pitches, multiple levels, chimneys and penetrations all add labour.
Is it cheaper to repair or replace my roof?
If the roof structure is sound and the problem is localised (a flashing, a rusted valley, storm damage), a repair in the hundreds of dollars is usually right. When rust or leaks are widespread, repair money stops buying life and a replacement becomes the economical choice. An honest assessment of which side of that line your roof sits on is part of every Quality Roofing quote.
How do I compare roofing quotes properly?
Check that each quote covers the same scope: scaffolding, old material disposal, underlay, flashings, insulation top-up, purlin replacement allowance and GST. A low quote that excludes scaffolding or disposal is not a low quote. Also confirm the installer is a Licensed Building Practitioner and carries public liability insurance.
