New Zealand buildings use a wide range of roofing materials and systems, each suited to different building designs, environments, and performance requirements.
Understanding the basic differences can help homeowners ask informed questions, compare proposals, and have clearer conversations with their roofing contractor.
The information below provides a general overview only. For more detailed guidance, refer to the RANZ Re-Roofing Guide or speak with a qualified roofing professional.
An introduction to roofing materials.
Metal Roofing
Metal roofing is one of the most common roofing materials used in New Zealand.
It is lightweight, durable, and suitable for both residential and commercial buildings. Metal roofing is available in a range of profiles and colours, and can be installed on new builds and reroofing projects.
Membrane Roofing
Membrane roofing systems are typically used on low-slope or flat roofs. Commonly found on commercial buildings and modern residential designs, they require specialist design and installation to ensure correct drainage, waterproofing, and performance.
Tile Roofing
Tile roofing includes metal, concrete and clay tiles.
Tile roofs can be heavier than other roofing options and rely on the supporting structure to be designed accordingly. They are common in older housing stock and some new residential developments.
Slate and Shingle Roofing
Slate and shingle roofing systems are less common in New Zealand but are sometimes used on heritage buildings, high-end residential homes, or architectural projects. These systems may use natural slate, fibre-cement slates, or timber shingles.
Roofing systems overview.
Roofing systems describe how a roof is put together and how it manages insulation, ventilation, moisture, and temperature within the building. While the roofing material forms the visible outer layer, the system beneath it plays a critical role in how the roof performs over time.
The right roofing system can help improve comfort inside the building, reduce condensation risk, and support long-term durability.
The wrong system, or one that is poorly designed or installed, can lead to issues that are difficult and costly to remedy.
Different buildings require different approaches. Factors such as roof design, building use, climate, and existing construction all influence which system is appropriate. For this reason, roofing systems should always be considered as part of an overall design, rather than as a one-size-fits-all solution.

This page provides a high-level overview of common roofing materials and roofing systems used in New Zealand. While it is designed to help homeowners understand the basics, every building and roofing project is different.
Roof design, materials, insulation, ventilation, and installation methods all interact, and decisions made early in the process can have long-term implications for performance, durability, and maintenance. For this reason, it is important to seek project-specific advice from a qualified roofing professional before proceeding with any roofing work.
For more detailed, practical guidance, the RANZ Re-Roofing Guide is available as a free consumer resource. Developed by industry professionals, the guide provides clear explanations, best-practice information, and helpful context to support informed decision-making throughout the reroofing process.
