Roofing in Upper Hutt

Two separate ones: a manufacturer warranty on materials (often 20-50 years, sometimes conditional on certified installation) and the contractor's own workmanship warranty (5-10 years is respectable). Get both in writing and understand what voids them — foot traffic, unventilated attics and pressure washing are common exclusions.

Missing, cracked or slipped tiles/shingles; granules collecting in gutters; daylight visible in the attic; damp patches or staining on top-floor ceilings; sagging roof lines; and moss holding moisture against the surface. Catching these early usually means a repair instead of a replacement.

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.

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.

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.
