Are you considering upgrading your roof to something that’s durable, attractive, and can stand the test of time? Then you’ve likely come across stone coated roofing tiles. These roofing materials combine the robustness of metal with the aesthetics of traditional tiles, offering a mix of style and functionality that’s hard to beat.
But what exactly are stone coated roofing tiles? How do they work, and why should you consider them over other roofing materials? In this detailed guide, we’ll dive deep into everything you need to know about stone coated roofing tiles—from the different types available, how they’re made, their benefits, and even how to maintain them.
What Are Stone Coated Roofing Tiles?
Stone coated roofing tiles are metal roofing panels coated with stone chips. The metal base—often made from steel—provides durability, while the stone coating offers aesthetic appeal and protection against the elements. Unlike traditional roofing materials like asphalt shingles or clay tiles, stone coated tiles offer both the lightweight characteristics of metal roofing and the charming look of more conventional materials.
Why Are They Popular?
In recent years, stone coated roofing tiles have become increasingly popular due to their balance of form and function. They offer:
- Durability: These tiles can last for decades, resisting weathering, impact, and even fire.
- Aesthetic Flexibility: You can achieve almost any look, whether you want a Mediterranean-style home or something more modern.
- Low Maintenance: Once installed, they require little upkeep compared to other types of roofing.
Now, let’s dive into the specifics, starting with the materials and types of stone coated roofing tiles.
A Popular Alternative to Stone Coated Roofing Tiles
Before diving into the details of stone coated roofing tiles, it’s worth briefly discussing corrugated iron sheets, another popular roofing option. Corrugated iron is favored in areas where budget-friendly, durable roofing is a priority. They are made from galvanized steel or aluminum and have a ridged appearance, which adds to their structural strength. But, when compared to stone coated tiles, corrugated iron sheets often fall short in terms of aesthetics and soundproofing. While durable, they lack the refined, high-end look of stone coated tiles and are more prone to noise during rainstorms.
Corrugated Iron Sheets vs. Stone Coated Roofing Tiles:
- Durability: Both are highly durable, but stone coated tiles offer better longevity due to the added protection from the stone coating.
- Noise Reduction: Corrugated iron sheets can be noisy in rain, while stone coated tiles have a sound-dampening effect thanks to the stone granules.
- Appearance: Stone coated tiles offer a more refined, traditional look, whereas corrugated iron sheets have an industrial appearance.
- Price: Corrugated iron sheets are often cheaper upfront but may require more maintenance over time.

How Stone Coated Roofing Tiles Are Made
Stone coated roofing tiles go through a meticulous manufacturing process to ensure both durability and aesthetic appeal. Here’s a breakdown of how these tiles are typically made:
- Metal Base Creation: The process starts with creating the metal base, usually made from galvanized steel or aluminum. The metal is pressed into the desired shape, such as shingle or tile profiles.
- Coating Application: After forming the metal, a coating of acrylic or other adhesive material is applied.
- Stone Chip Layer: Next, the stone chips (typically made from natural materials like granite) are applied to the adhesive-coated metal. These chips are what give the tiles their signature appearance and extra durability.
- Baking and Curing: The tiles are then baked to harden the coating and ensure that the stone chips are firmly attached.
- Final Sealing: Finally, the tiles are sealed with a protective layer to further prevent weathering and corrosion.
This process results in a roofing material that combines the strength of metal with the aesthetic versatility of stone.
Key Components of Stone Coated Roofing Tiles
| Component | Function |
|---|---|
| Steel Base | Provides the strength and structure of the tile. |
| Acrylic Coating | Protects the steel base and provides an adhesive layer for the stone chips. |
| Stone Chips | Adds durability, weather resistance, and aesthetic appeal to the tile. |
| Protective Sealant | Offers an additional layer of protection from UV rays, rain, and other weather conditions. |
| Baked Finish | Hardens and strengthens the entire tile for maximum durability. |
Working Process of Installing Stone Coated Roofing Tiles
The installation process of stone coated roofing tiles involves several steps to ensure proper fit and durability. Let’s walk through the steps:
- Surface Preparation: Before installation begins, the roof’s surface must be properly prepared. This involves removing old roofing materials and inspecting the roof decking for damage.
- Underlayment Installation: A waterproof underlayment is applied to protect the roof from water damage.
- Laying the Tiles: The tiles are installed in overlapping rows, starting at the bottom of the roof and working upward.
- Securing the Tiles: Special nails or screws are used to secure the tiles to the roof decking, ensuring they can withstand wind and other harsh weather conditions.
- Trimming and Sealing: The final step is to trim any excess tile material and seal the edges to prevent water infiltration.
Key Installation Tools and Techniques
| Tool | Function |
|---|---|
| Tile Cutter | Used to cut tiles to fit the edges and corners of the roof. |
| Roofing Nails/Screws | Fastens the tiles securely to the roof decking. |

Frequently Asked Questions (FAQ)
1) Do stone coated roofing tiles perform well in high-wind and hail zones?
- Yes. Many products are tested to UL 2218 Class 4 (hail impact) and can meet ASTM D3161/UL 580/UL 1897 wind uplift ratings. Verify the specific product’s test reports for your local code.
2) What’s the typical installed cost per square (100 sq ft) in 2025?
- In North America, $650–$1,050 per square installed depending on profile, underlayment, roof complexity, and region. Materials alone are often $300–$550 per square.
3) How do stone coated metal tiles compare to asphalt shingles on lifecycle cost?
- Although upfront costs are higher, 50-year service life, lower maintenance, potential energy savings, and insurance discounts in hail/wind regions often deliver a lower 30–50 year total cost of ownership.
4) Can stone coated roofing tiles be installed over existing shingles?
- Often yes, with a proper inspection, deck integrity confirmation, and ventilation plan. Some jurisdictions require tear-off—check local codes and manufacturer guidelines.
5) Are the stone chips prone to shedding or fading?
- Quality systems use UV-stable ceramic-coated granules and acrylic binders with oven-curing. Minimal granule loss is normal early on; long-term color stability depends on brand, climate, and maintenance.
