GERARD PRESSED PRESSED STEEL ROOFING OVERVIEW
A load off your mind in earthquake areas.
With their combination of lightweight and superior strength, Gerard pressed steel roofing can place significantly less stress on structures weakened by earthquake or fire. For example, a 10 tonne concrete or clay tile roof area could weigh as little as one tonne with Gerard smooth pressed steel roofing, or 1.7 tonne with Gerard textured pressed steel roofing. Either way, it's a very reassuring difference when the earth starts to move. If you live in an earthquake-prone area. Lightweight and strong, the Gerard Roofs were well-tested in the recent Canterbury earthquakes. Major earthquakes in Los Angeles and Japan have show the combination of heavy tiles on inadequate framing almost always results in serious structural damage.
Holds strong in high winds
New Zealand building regulations require roofing to withstand a wind loading of 1.8kPA. With no additional fastenings or special materials, Gerard's pressed steel roofing system has been proven to withstand wind loading of more than 6kPA, which is equivalent to a wind speed of 350kph (stronger that the wind force at the centre of a category 5 hurricane) Other roofing systems require specialised fastenings and or materials for high wind zones.
Even if your home is built at the edge of the sea, your Gerard roof won't require any special materials, additional coatings or extra fastenings to ensure ongoing performance. Testing shows that zinc-aluminium coated steel roofing materials, such as Gerard pressed steel, have up to eight time the corrosion resistance of other steel roofing products.
UV PROTECTION maintenance INSTALLATION
When any material is continuously exposed to the sun, some colour fading is inevitable. However, Gerards UV protection technology and special light-fast pigments provide superior resistance against fading and discolouration.
The only maintenance that a Gerard pressed steel roof requires is a clean with an appropriate roof wash every three to five years, to help prevent the growth of algae, moss and lichen.
Gerard roofs can only be installed by Gerard Certified Roofers, experienced professionals who are trained to install correctly every time.
Gerard pressed steel roofing exceed the world's most stringent fire test standards. They are also securely interlocked, which prevents hot embers from neighbouring fires blowing up into the roof space. They are lightweight, so they are less likely to fall on anyone while a house burns. They are weakened by fire, a home with a concrete tile roof will crumple much quicker due to the extra weight.
