Our Advanced Coating Technology for the stone coated roofing is one of the reasons Wichtech Gerard® Roofs always look consistently good and retain their looks for a lifetime. It’s one thing to make a stone coated roofing tile that looks like Gerard®, but it’s quite another to make one that still looks like Gerard® a year after installation.
At Gerard® we apply a thick layer of our patented basecoat to our Alu-Zinc steel and to stick our Natural Stone Chips to the steel. We apply a thick layer so that the stone chip sinks deep into it, ensuring a super-tight hold. We then repeat the process of applying the stone coating using smaller chips to fill any gaps. This ensures a 100% covering, especially when the tile is bent during installation (down into a valley or up against a wall or chimney). Our basecoat has been developed over decades of continual improvement to do one job – stick stone chips to alu-zinc steel, and it does it for a lifetime.
When chip loss occurs, it exposes the steel to the elements and it begins to corrode and rust. This can happen prior to installation, during transport, handling and during the installation process itself. This means that there is a high risk that a fake stone coated Gerard® roof will be rusting from day one of installation, if not before. Unfortunately, the only way to rectify this problem is to replace the roof. And the cost of doing this is more than choosing Genuine Gerard® stone coated roofing in the first place.
