For decades, the Indian roofscape was dominated by two extremes: heavy, fragile clay tiles or industrial-looking, noisy metal sheets. However, as modern Indian architecture evolves towards “Sustainable Luxury,” a new gold standard has emerged: Stone-Coated Metal Roofing.
At Darted, with over 17 years of expertise in fabrication and exterior solutions, we’ve seen how the right roof can transform a house into a high-performance sanctuary. In this guide, we’ll explore why stone-coated steel is the smartest investment for Indian homeowners and developers in 2026.
What exactly is Stone-Coated Metal Roofing?
Unlike standard corrugated sheets, stone-coated roofing is a sophisticated multi-layered system. It starts with a high-grade structural steel core, which is then coated with an AZ-150 Galvalume alloy (Aluminum-Zinc).
The “magic” happens on the surface: natural stone granules are embedded in an acrylic polymer bit, followed by a final clear glaze. The result? A roof that has the aesthetic depth of traditional stone or shingles but the unbreakable strength of steel.
Why it’s Built for the Indian Climate
A. Beating the Heat (Thermal Insulation) In regions like Rajasthan, where temperatures soar above 45°C, standard metal roofs turn houses into ovens. Stone-coated tiles reflect a significant portion of UV rays. Furthermore, the installation creates a “dead-air” space between the tile and the roof deck, acting as a natural thermal barrier that keeps interiors up to 5-8°C cooler.
B. The “Silent” Metal Roof One of the biggest complaints about metal roofing is the noise during monsoons. The thick layer of stone granules on Darted tiles acts as a natural sound dampener, breaking the impact of raindrops and ensuring your home remains peaceful even during a heavy downpour.
C. Lightweight Strength A traditional clay tile roof can weigh up to 45kg per square meter. A Darted stone-coated roof weighs only about 6-7kg per square meter. This massive reduction in weight means you can save significantly on the cost of the underlying structural steel or timber frame.
Comparison: Stone-Coated vs. Traditional Materials
| Feature | Stone-Coated Metal | Clay/Concrete Tiles | Standard GI Sheets |
| Lifespan | 50+ Years | 15-20 Years (Fragile) | 10-15 Years (Rusts) |
| Weight | Very Light (6kg/sqm) | Very Heavy (45kg/sqm) | Light |
| Heat Reflection | Excellent | Moderate | Poor |
| Noise Control | Excellent (Dampened) | Good | Very Poor |
| Aesthetics | Premium/Architectural | Traditional | Industrial |
