A Unique Product Range With New Zealander’s In Mind

Calder Stewart Roofing offer a wide range of products specifically designed for New Zealand’s rugged environment. Coming from the deep south our products have being tested & developed in some of the wettest & windiest parts of the country.

Our products have endured harsh alpine conditions, extreme temperatures and a destructive native parrot known as the Kea. All of this has being a key part of the learning process in developing a full range of products designed to meet the needs of all New Zealanders, whether that be at home, on the farm, the ski lodge or the or a plush architectural retreat.
