Key takeaways
- Most roofing jobs in New Zealand land between NZ$300–NZ$45,000 — known locally as roofer.
- Like-for-like roof replacement is generally exempt from building consent under Schedule 1 of the Building Act, but structural alterations are restricted building work requiring a Licensed Building Practitioner. WorkSafe height rules make scaffolding or edge protection a standard cost on most jobs.

What affects the price
- Job size and scope — bigger or more complex jobs move you up the ranges above.
- Access and condition — hard-to-reach areas, older properties or neglected maintenance add labour time.
- Materials and quality level — where materials are involved, the grade you choose often matters more than labour.
- Urgency — same-day or out-of-hours work usually carries a premium.
- Where you live — large metros in New Zealand typically run above the national range; smaller towns below it.
How to save
- Get at least three quotes and compare like-for-like scopes, not just totals.
- Be flexible on timing — off-peak slots are often cheaper.
- Bundle related tasks into one visit to spread call-out costs.
- Agree the scope in writing up front to avoid change-order surprises.
How to hire a roofing pro in New Zealand
- Like-for-like reroofing is generally exempt building work, but structural changes are restricted building work needing a Licensed Building Practitioner (LBP)
- Check Roofing Association of New Zealand (RANZ) membership and local references
- Expect scaffolding/edge protection in the quote — WorkSafe requires it on most roof jobs and it can add $1,500-$3,000+
- Confirm the quote covers new underlay, flashings and disposal, and states whether GST is included
- Book for spring-summer; coastal wind zones may need higher-spec fixings
- Get manufacturer and workmanship warranties in writing
Red flags
- No edge protection priced on a full reroof
- Structural work proposed without an LBP
- Quotes silent on GST
- Reusing rusted flashings on a new long-run roof
- Full payment upfront

Frequently asked questions
Is moss on a roof actually a problem?
Yes, over time — moss holds moisture against the surface, lifts tile and shingle edges, and accelerates frost damage. Have it removed by soft washing or manual scraping, never high-pressure washing, which strips granules and forces water under the covering. Zinc or copper strips slow regrowth.
Should I repair my roof or replace it?
Repair when damage is localised — a few slipped tiles, one flashing leak — and the roof is under about two-thirds of its expected life. Replace when leaks recur in different places, more than roughly 30% of the covering is failing, or repair quotes start approaching a third of replacement cost. A good roofer will show you photos from the roof to justify either answer.
Can a new roof be installed over the old one?
Sometimes — an overlay saves tear-off cost but hides deck problems, adds weight, and often shortens the new roof's life and warranty. Many codes and manufacturers limit roofs to two layers. Tear-off costs more upfront and is usually the better long-term decision; get both options priced.
Why do roofing quotes vary so much?
Access and safety costs (scaffolding, edge protection), roof pitch and height, tear-off vs overlay, material grade, and how honestly hidden deck repair is priced. A low bid that excludes safety equipment and deck contingency isn't cheaper — it's just billed later.
Should gutters be replaced at the same time as the roof?
Often worth it: the access equipment is already up, edge details integrate cleanly, and combined pricing beats two separate jobs. If your gutters are under ten years old and sound, keep them — but have the roofer protect them during tear-off and note their condition in writing.
How much does reroofing cost in New Zealand?
Long-run steel — the most common covering — typically runs NZD $90-$190 per m² installed, putting a small home at $12,000-$28,000 and larger houses at $20,000-$45,000 including scaffolding. Concrete tile and membrane roofs price similarly to slightly higher.
Do I need building consent to reroof in NZ?
Usually not — replacing the covering like-for-like is exempt work. Consent is needed if you change the roof structure, alter the profile substantially, or switch to a much heavier material. Your roofer or council can confirm in minutes.
