TWO ADVANTAGE OF STONE COATED METAL ROOF TILES MORE CUSTOMER CONCERN POINTS

#1 Best for Noise Reduction

Sangobuild® stone coated roofing tiles do more than just look good. Even though they are durable for generations, there’s one question that’s always asked: “are they noisy when it rains?”.

The answer may surprise you. Although Sangobuild® tiles are made of alu-zinc steel, they are much quieter than other types of metal roof such as long run. Our high-quality stone chip coating is responsible for this for two reasons.

Firstly, the non-metallic stone coating doesn’t refract the rain like a metal surface does. Secondly, the irregular shapes of our stone chips disperse raindrops, diluting their noise effect.

The graph to the left demonstrates that a Sangobuild® roof is almost 10 decibels quieter than a long run roof and around 5 decibels quieter than corrugated galvanised steel sheets. So even if you’re considering a mono-pitched roof or a hidden roof, it’s well worth considering these figures.

Of course, there are all the other benefits of Sangobuild® to also consider!

While concrete tiles are a little quieter still, there’s the breakage issue to consider with these, along with the usual problems with organic growth.

#2 Colour That Doesn’t Change

One of the major differences between Sangobuild® and other “stone coated roof tiles” is the quality of our stone coating.

While other manufacturers scour the world looking for the cheapest stone chip, Sangobuild® uses only the toughest volcanic stone from quarries in New Zealand. This stone chip is proven to perform in any weather condition and is part of our famous 50 year warranty. So, what makes Sangobuild® stone chip different?

From a home owners point of view it’s all about the colour. Once installed on a roof, the stone chip is exposed daily to UV from the sun. This usually bleaches non-Sangobuild® stone coated tiles and the colour soon fades. We’ve seen this happen from as little as three months after installation, but it usually occurs after a year or two. Try going back to the place you bought your roof from to complain!
