Zinc Roofing & Cladding Contractors

Zinc has an 80 + year life expectancy with manufacturers offering material guarantees on their products.
Zinc is self-protecting as it forms its own protective layer called patina. (When zinc is exposed to the moisture and carbon dioxide that is present in our atmosphere, a protective layer of zinc carbonate forms on its surface, prohibiting the corrosion process.)
Zinc is suitable for use in coastal environments.
Zinc is low maintenance and lightweight thus requiring a more minimal support structure.
If you are looking for an environmentally friendly metal material, zinc is both recyclable and sustainable.
Untreated zinc has an A1 non-combustible rating with treated or coated zincs having an A2 rating.
Zinc is a fungistat, which means it prohibits the reproduction of mould, mildew and fungus. This can greatly reduce the risk of moss or even black mould from forming on the exterior of a building in areas that are in contact with the zinc metal.
Zinc is a malleable metal so can be formed into complex and curved shapes, hence why it is popular with architects.
Zinc works well with both contemporary and traditional designs and is a popular choice for both commercial and residential projects.

If a zinc roof or zinc wall construction is not designed or installed to allow for ventilation or a robust vapour control layer, then corrosion can occur to the underside of the zinc.
Zinc can become brittle when installing at temperatures below 10°C. It is essential to ensure that the material is warmed using a hot air gun.
As with all hard metals ‘oil canning’ or surface deflection may be visible. This can be exaggerated by the intensity or direction of light and is subjective in the eyes of the designer. This distortion can be minimised in pre-fabrication and by Varla’s good workmanship and care when handling and installing the zinc.
