Specifying with Gerard

Specification today is more challenging than is has ever been. There are supply chain pressures pushing out lead times, councils putting extra pressure on architects to be accountable for their products and no easy way to substitute products. That's why specifying the right product becomes so important. We understand that when you are up against a deadline, you want to talk to an expert, someone who knows what they are talking about and can help you get your projects across the line. Relationships are important to us and if you're looking at roofing materials, have a chat with us and see how we can help.

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 sun

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

Gerard’s steel panel roofing systems have been proven to withstand cyclic wind loadings and are suitable for projects with Wind Class C2. Testing conducted to AS 4040.3 by NZMRM, Auckland, New Zealand.
