Why We Use It

Extreme Corrosion Resistance

Built with a zinc, aluminium, and magnesium alloy coating that delivers exceptional protection in New Zealand’s toughest coastal environments. MagnaFlow is made to perform where salt, sea air, and moisture destroy ordinary roofing systems.

Long-Term Colour Stability

The advanced ColorCote paint technology resists fading, chalking, and gloss loss — even under New Zealand’s high UV conditions — keeping your roof looking sharp for years.

Superior Coastal Performance

Designed specifically for extra-high corrosion zones, MagnaFlow is the go-to solution for homes in Levin, Foxton, Waitārere Beach, and the wider Kāpiti Coast. It’s engineered to handle what the sea throws at it.

Weather Protection

The tough coating system forms a watertight barrier against the elements, helping your roof shed rain efficiently while protecting against surface wear and long-term damage.
