Re-Roofing Specialists in Auckland

A full re-roof in New Zealand costs $15,000 to $35,000 for a standard three-bedroom home. Colorsteel or Zincalume long-run roofing costs $80 to $120 per square metre installed. Concrete tile roof replacement costs $90 to $140 per square metre. Metal tile (such as Metrotile or Decra) costs $85 to $130 per square metre. These prices include removal and disposal of old roofing, new underlayment, flashings, and ridging. The total cost depends on roof size, pitch, complexity, and accessibility.

Signs your Auckland home needs a re-roof include persistent leaks despite repairs, widespread rust on metal roofing, cracked, broken, or missing concrete tiles, sagging roof lines (indicating structural issues beneath), the roof being over 40 to 50 years old, and interior water stains or mould. A professional roofer can inspect your roof and advise whether repairs or a full replacement is more cost-effective. As a general rule, if repair costs exceed 30 percent of replacement cost, re-roofing makes more sense.

The most popular re-roofing material in New Zealand is Colorsteel long-run metal roofing by New Zealand Steel. It comes in a wide range of colours and profiles (corrugate, tray, and standing seam) and is backed by a 15 to 30 year warranty depending on the product and location. Concrete tiles are durable but heavy — check that your roof structure can support them. Metal tiles (Metrotile, Decra, Gerard) offer a tile look with lighter weight. For coastal areas within 500 metres of the sea, use a marine-grade product rated for your corrosion zone.

A like-for-like re-roof (replacing with the same material) is generally exempt from building consent under Schedule 1 of the Building Act 2004. However, if you are changing roofing material (for example, tiles to metal), altering the roof structure, or changing the roof pitch, a building consent is likely required. Always check with your local council. Re-roofing work must comply with NZS 3604 and the E2 weathertightness provisions of the Building Code. Use a licensed roofer for all re-roofing work.
