Company

AHI Roofing was created nearly 50 years ago when Lou Fisher, a genuine New Zealand innovator, produced the world's first steel tile. Now one of New Zealand's most successful roofing manufacturers, AHI Roofing utilises leading edge technology to produce the extensive Gerard Roofs range of profiles, colours and finishes.

Gerard Roofs are now exported to over 70 countries, covering and protecting over a million homes and buildings around the world. Whether in the salt-laden air of the Pacific, the searing heat of the Sahara desert or the arctic storms of Greenland, our dedication to quality and innovation, combined with the proven strength and durability of our roofs, give Gerard Roofs the deserved reputation of world leaders in steel roof tile technology.

Installation of our products is always carried out by Gerard Certified Roofers - experienced professionals trained to provide homeowners, designers and builders with unrivalled advice and service.

There are over 90 Gerard Certified Roofer Companies nationwide, many have re-roofing and roof restoration specialist operations as well as new roof options.

Gerard Roofs are the versatile range of steel tiles asked for by name and demanded by trade professionals and discerning homeowners around the world. AHI Roofing manufactures and markets Gerard Roofs.
