Roofing in Nelson

Yes — replacing one slope or section is common after localised storm damage and costs far less than a full reroof. The trade-offs are colour mismatch with weathered existing material and tying new work into old underlayment. It makes most sense when the rest of the roof has meaningful life left.

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.

Tear-off and disposal, underlayment spec, flashing replacement (not reuse), ridge and valley details, a unit price for replacing rotten decking discovered mid-job, scaffolding or edge protection, and cleanup with a magnetic nail sweep. A quote missing the deck-repair unit price is the classic setup for large mid-job extras.

Typically 10-30%, or enough to cover ordered materials, with the balance staged against progress and completion. Never pay in full upfront, and be wary of anyone who can start 'tomorrow' if you pay cash today — good roofers have lead times.

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.

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.
