A new roof is often a once-in-a-generation purchase. This guide helps you compare the important details before signing — so the cheapest quote and the best quote stop being the same guess.

Make sure each roofer is pricing the same roof area, access, disposal, flashings, underlay, fixings, and edge details. Identical written scopes are what turn three quotes into a real comparison instead of three different jobs at three different prices.
Compare durability, coating tier, colour, profile, maintenance requirements, and supplier warranty rather than price alone. The right coating for your distance from the coast matters more than the brand on the brochure.
Residential building work above the legal threshold requires a written contract. Check payment stages match progress on site, variations need written approval, and warranty terms for both materials and workmanship are spelled out before you sign.
Ask how the job is staged, how the roof stays weatherproof between work days, and what happens to the programme when rain hits. A realistic timeline with weather allowance beats an optimistic one that slips.
Restricted building work must be carried out or supervised by a Licensed Building Practitioner. Confirm who holds the licence, who is actually on the roof, and that public liability insurance is current — before work starts, not after.
Ask what photos, warranties, maintenance notes, and quality checks will be provided before final payment. The close-out pack protects your warranty position for decades — treat it as part of the product you are buying.
Full Tree helps scope, compare, and coordinate coated metal roofing enquiries for COLORSTEEL® and ColorCote® projects. We are not a council, certifier, or legal adviser, so consent, contract, and compliance decisions should be confirmed with the relevant professionals.
Full Tree is headquartered in Auckland, where most of our projects are based, and we now support coated steel roofing projects across New Zealand — including Waikato, Bay of Plenty, Wellington, and South Island regions such as Canterbury and Otago. Tell us your location when you enquire and we'll confirm coverage for your project.
Possibly. Some low-risk or like-for-like work may be exempt, but all building work in New Zealand must still comply with the Building Code. If the job affects structure, weathertightness, fire performance, drainage, or an existing consented element, check with your local council before work begins.
Restricted building work on homes and small-to-medium apartments must be carried out or supervised by the right Licensed Building Practitioner. Roofing, structure, external moisture management, and consented weathertightness details are areas where LBP involvement may matter.
Ask for a written scope covering roof area, access, profile, coating system, underlay, fixings, flashings, penetrations, gutters, waste removal, payment stages, warranty documents, exclusions, and how variations will be approved. Residential building work over the legal threshold requires a written contract, and a written agreement is sensible for smaller jobs too.
Residential building work in New Zealand has statutory implied warranties under the Building Act, separate from any manufacturer material warranty. Product warranties for COLORSTEEL® or ColorCote® systems usually also depend on correct installation, suitable specification, and ongoing maintenance.
Raise the issue in writing, include dated photos, keep the contract and variation records, and give the contractor a fair chance to inspect and respond. If a dispute remains unresolved, options may include the contract process, mediation, the Disputes Tribunal, or a Building Act determination for certain Building Code or consent-related matters.
