A commitment to future generations

A Gerard roof is an environmentally friendly choice. It’s lighter than concrete or clay roofing, so transportation is more energy-efficient, it requires less framing support, which saves resources and it’s made from steel, which is endlessly recyclable.


Gerard's stance is backed with solid green credentials

Gerard was the first roofing company in New Zealand to be accredited with ISO 14001 Environmental Management certification and is now the first to carry the internationally recognised Declare label.

For customers and specifiers, Gerard’s Declare status automatically boosts points for Homestar and Greenstar applications.

Transporting a pressed steel roof requires less energy

Concrete and clay tiles can be bulky and heavy. One houselot would require one average-size truck for transport. The same truck could carry enough Gerard pressed steel roofing for about 10 homes, using less energy (and therefore less carbon) to transport.

A Gerard roof requires less framing timber

A pressed steel roof requires much less framing support than concrete tile. On average, a comparable pressed steel roof can save as much as $2000 worth of framing materials and $1000 in labour costs; with the attendant environmental benefits associated with the saving.

Steel tile can be recycled again and again

Steel is 100% recyclable and arguably the most eco-friendly material in the world. It can be recycled infinitely, without losing any of its qualities. So when a Gerard roof reaches the end of its useful life, it doesn’t need to end up in landfill, it can be re-worked into another steel product.

Facts about recycling steel

Due to its magnetic properties, steel is easy to separate from waste streams, enabling high recovery rates.

Even the by-products arising from steel production are all reused. For example, the slag is employed as a high-value mineral material for highway construction, as ballast, and for the manufacture of cement.

Environmental responsibility goes beyond just products

Gerard Roofs is actively working towards reducing the environmental footprint of the company, its manufacturing methods and its products.

During Gerard's two Sustainability Fortnights, our people planted 2767 trees.

At Gerard, 'sustainability' means a pledge of ongoing improvement

Sustainability by definition is inherently broad. Generally, however, there is a commonly understood idea of sustainability – the capacity for continuance into the long term. Sustainability is a process, a journey without an end; continuous improvement is the end in itself.
