Roofing Costs in New Zealand

The pricing of roofing in New Zealand is based on materials, design, and the level of complexity for the project. A small roof can begin at a cost of about $6,000.
The majority of average houses use anywhere between $12,000 and $25,000 for a complete roof replacement. High-quality jobs with high-end tiles or slate can run upwards
of $40,000.

Costs will vary with the type of roof construction that is being done. Simple ones will be cheaper, and the more complicated and steeper roofs will cost more. Above that, the more scaffolding or protective equipment needed for your job, the higher the price for the labour goes. Coastal homes can also require salt-proofing materials, which increases the overall cost.

With a roofing calculator, you can acquire an initial figure. However, the most accurate way to determine the cost is by requesting quotes from local roofers who can visit your home for a detailed assessment.

Roofing Material Choices and Their Price

New Zealand homeowners have various roofing materials at their disposal, all with their own price and lifespan.

• Concrete and Asphalt Tiles These are budget options. They cost between $55 and $80 per square metre. They are available in several different colours and can be made to appear terracotta without the expense. High-end concrete tiles are a little more expensive but still inexpensive relative to slate.


• Terracotta Tiles Terracotta is resilient and fashionable. It is more expensive at $120 to $160 per square metre. Installation is also more involved, adding to the cost of labour. Terracotta is favoured by most homeowners because it is more durable than concrete.


• Slate Roofing Slate is the most costly option. It ranges from $200 to $280 per square metre. The advantage is durability and a life expectancy of 75 years or more. Certain slate roofs can last centuries with good maintenance.


• Colorbond Roofing Colorbond steel costs between $50 and $70 for each square metre. It is light, durable, and frequently carries lengthy warranties. Special marine-grade Colorbond is suitable for houses close to the beach, where salt is a problem.

With the transition from lighter materials to heavier materials such as slate or terracotta, additional structural support might be necessary. This will increase expenses again.
