Metal roofing in New Zealand costs $70 to $130 per square metre installed for standard Colorsteel long-run profiles. Corrugate profile is the most affordable at $70 to $90 per square metre. Tray profile costs $80 to $110 per square metre. Standing seam (the premium option) costs $100 to $150 per square metre. These prices include the roofing iron, underlayment, flashings, fixings, and installation. A complete metal roof for a standard three-bedroom home costs $12,000 to $25,000.

Colorsteel by New Zealand Steel is the dominant metal roofing brand in NZ. Key products include Colorsteel Endura (standard, for most urban and rural areas, 15 year warranty), Colorsteel Maxx (enhanced corrosion resistance, for areas within 500 metres to 1 kilometre of the coast, 15 year warranty), and Colorsteel Dridex (anti-condensation backing, reduces dripping in uninsulated roofs). Zincalume is an unpainted zinc-aluminium coated steel option. Choose your corrosion zone rating based on distance from the coast and local conditions.

Common metal roof profiles in New Zealand include corrugate (the classic NZ roof profile, economical and suitable for low to steep pitches), tray or trapezoidal (clean modern look, good water carrying capacity), and standing seam (premium concealed-fix profile, no exposed screws, popular on architectural homes). The minimum roof pitch for metal roofing varies by profile — corrugate requires a minimum 8-degree pitch, while tray profiles can go as low as 3 degrees. Your roofer will advise on the best profile for your roof design.

If your Kapiti Coast property is near the coast, corrosion zone ratings are critical for metal roofing selection. Zone C (100 to 250 metres from breaking surf) and Zone D (less than 100 metres) require marine-grade products with enhanced corrosion protection. Colorsteel Maxx is rated for these environments. Standard Colorsteel Endura is suitable for Zone B (250 metres to 1 kilometre). Using the wrong product in a coastal environment will void your warranty and lead to premature corrosion.
