Made from the highest quality materials

Made from only the best steel and the highest quality stone, our ISO9001 manufacturing facilities, uphold the highest standards from product sourcing, through manufacturing to delivery of materials and beyond.

The steel is coated with a zinc-aluminium alloy, combining the corrosion protection of aluminium with the sacrificial protection of zinc to create an alloy that's ideal for roofing and with a serviceable life that far exceeds galvanised products and other roofing materials.

Our tiles are painted once they have been pressed and formed. This ensures that the paint doesn't fracture or crack during the forming process. Our tiles go through an extensive Quality Assurance process and our coating technology makes for the extremely long serviceable life.

30 Year Weather Performance Warranty

Our extensive warranty provides you peace of mind, knowing that your home is protected for decades to come.

The cost or removing your existing roof too expensive?

Sometimes the cost of removing an existing roof is expensive, especially if that roof contains asbestos. With our innovative Concealed Fastening range, it some cases it possible to lay a roof straight over your existing one, saving time and money.

Performance benefits

  • Save money and stay safer

    With less weight above you in an earthquake or fire there is less pressure on the structure keeping your roof up. Not only do you save on structural costs, but a Gerard roof keeps you safe.

  • Good for you. Good for the environment

    Gerard was the first roofing manufacturer in New Zealand to attain ISO 14001 certification and steel is an infinitely recyclable resource. So the roof you put on today will continue to be utilised for generations to come.

  • Highest possible impact resistance rating

    Gerard roofs are engineered to the highest standards to resist the impact of hail and have received the highest possible impact resistance rating.

  • Lightweight

    Gerard roofs are both lightweight and easy to install. One of our roofs can weigh up to 10 x less than a concrete roof.

  • Best in class fire rating

    Gerard's roof panels are securely interlocked so embers can't find their way into your roof space, making them amongst the most fire-safe roofs available. They're even approved for Australia's highest bush fire zone (BAL-FZ)

  • Great in the cold

    Impervious to snow, frost or ice. Their strength-to-weight ratio means with proper design, they can easily withstand heavy snow loadings.

  • Stand up to the harsh NZ sun

    Our textured and smooth profiles have been engineered to stand up the New Zealand's harsh UV light to ensure the coating of your roof stands the test of time.

  • Stands up to the wind

    Gerard roofs have been proven to withstand wind loadings equivalent to wind speeds of 350kph (stronger the wind force at the centre of a Category 3 tropical cyclone). Testing conducted by James Cook University, Townsville, Australia
