Not Just Decoration - The Real Benefits of Stone Chips

If you've ever looked at a stone coated metal roof, you probably noticed the surface first. The rich texture, the natural color variations, the way it mimics clay tiles or slate without the weight. It's easy to assume the stone layer is just there to look pretty.

But that's not the full story. The truth is, those tiny stone chips do way more than decorate. They actually make the roof stronger. Much stronger.

Let's walk through the real benefits - not the marketing fluff, but the stuff that matters when you're choosing a roof for the next 40 or 50 years.

1. UV Protection

Strong sunlight breaks down adhesives and fades colors over time. The stone coating on a Sangobuild roof blocks UV rays before they reach the steel underneath. Sangobuild uses natural stone chips fired at 800°C - the color is locked in. No fading after 30 years of sun.

2. Weather Resistance

Stone chips take the beating from hail, wind-blown debris, and heavy rain. They also help the roof hold steady in high winds. And stone doesn't burn. Combined with the steel core, Sangobuild roofs earn a Class A fire rating - the highest possible.

Sangobuild uses a poured adhesive method, not spray. That means every stone chip stays bonded. No bare spots. No granule loss

3. Noise Reduction

Bare metal roofs are loud in the rain. Stone coated metal roofs are not. The rough, granular surface breaks up raindrop impact and absorbs sound. Sangobuild's stone coated metal roofing is actually quieter than many galvanized roof sheets and asphalt shingle roofs.

4. Beautiful Appearance - With Substance

The natural stone chips create a rich, earthy look that fits any architectural style. But the beauty isn't shallow. Because the color is fused into the stone at high temperature, it won't peel or fade. And the uniform bonding means no patchy sections. What you see five years in is what you'll see 30 years in. That's rare in roofing.

Stone Chips Make the Roof Stronger

How? By protecting the steel. Sangobuild uses alu-zinc steel (55% aluminum, 43.4% zinc, 1.6% silicon). The stone coating shields it from UV, moisture, and impact. That steel lasts six to nine times longer than ordinary galvanized steel.

One more thing - weight. Stone coated metal tiles weigh only 5–8 kg per square meter. Clay or concrete tiles weigh up to 50 kg. Lighter means easier installation and less structural reinforcement.

Bottom Line

Stone chips are not decoration. They block UV, resist weather, quiet the rain, and look good doing it. Sangobuild builds them the right way - French natural stone, high-temperature sintering, poured adhesive, and alu-zinc steel.

That's a roof that works. For decades.
