Stone coated metal roofing is a steel roof tile covered with stone granules. It weighs far less than concrete or clay tile. It can last for decades when the specification is right.
This guide is for importers, distributors and roofing contractors. It explains what the product is, how it compares with other roofing, what drives cost, and how to check a supplier before you order.
What Is Stone Coated Metal Roofing?
Stone coated metal roofing: A roof panel made from coated steel, topped with stone granules bonded by acrylic resin.
The panel is built in layers. Each layer has one job.
- Steel base: carries the load and gives the panel its shape.
- Protective metal coating: slows corrosion of the steel.
- Acrylic resin: bonds the stone granules to the panel.
- Stone granules: give color, texture and surface protection.
- Acrylic overglaze: seals the granule layer.
Weight is the main reason buyers choose it. Industry sources put stone coated metal roofing at about 150 pounds per square. A square is 100 square feet. That is roughly 7 kg per square meter.
Asphalt and concrete products can weigh 350 to 1,100 pounds per square. A lighter roof puts less load on the structure. It also makes handling and shipping easier.
Main Profiles and Where They Fit
Stone coated tiles copy the look of traditional roofing. You choose the profile first, then the color and granule finish.
| Profile | Look | Typical use |
|---|---|---|
| Shingle Tile | Asphalt shingle appearance | Residential re-roofing |
| Shake Tile | Wood shake texture | Villas, cabins, mountain homes |
| Roman Tile | Classic rounded tile look | Mediterranean-style homes |
| Milano Tile | European-style tile profile | Villas and townhouses |
| Bond Tile | Low-profile flat tile look | Modern and mixed-style projects |
Each profile has its own size, weight and installation method. Always request the technical sheet before you compare prices.
Stone Coated Metal Roofing vs. Asphalt, Concrete and Standing Seam
Short answer: Stone coated metal is lighter than concrete tile. It lasts longer than asphalt shingles. It offers more looks than standing seam metal.
| Stone coated metal | Asphalt shingle | Concrete tile | Standing seam metal | |
|---|---|---|---|---|
| Weight | About 150 lb/square | 350–1,100 lb/square (shared range with concrete) | 350–1,100 lb/square (shared range with asphalt) | Light |
| Look | Tile, shingle, shake | Shingle only | Tile | Clean vertical lines |
| Typical life | 30–50 years, per industry guides | 15–30 years | Long, but heavy | Long |
| Main trade-off | Higher upfront cost than asphalt | Shorter life | Structural load | Fewer style choices |
The main difference between stone coated and standing seam is appearance. Stone coated panels are stamped into tile shapes. Standing seam panels are long, flat metal sheets.
Q: Is stone coated metal roofing noisy in rain? A: Usually not. The granule texture helps reduce rain noise. Installation method and underlayment also matter.
Where your market uses heavy concrete tile, weight savings can reduce structural work. Where it uses asphalt, the longer life is the main argument.
What Drives the Cost of Stone Coated Metal Roofing?
Short answer: Specification drives price. Two panels can look the same and cost very different amounts.
Public price figures vary a lot. Consumer guides in the US quote installed prices of about $7 to $15 per square foot. Other guides quote $8 to $20 or more. These figures include labor, tear-off and local margins. They are not factory prices.
As a buyer, you need the panel price on clear terms. Ask for the specification first. Then compare quotes.
Specs That Change the Price
| Factor | Why it matters |
|---|---|
| Steel thickness | Thicker steel costs more and resists denting better |
| Metal coating type and weight | Affects corrosion resistance |
| Granule quality and coverage | Affects color stability and surface wear |
| Profile | Complex profiles need more tooling and material |
| Color | Custom colors may need minimum order quantities |
| Packaging | Affects damage rate and container loading |
| Accessories | Ridge caps, flashing and fasteners add to the order |
Q: Why do two suppliers quote very different prices? A: Their specifications usually differ. Compare thickness, coating, granules and packaging before you compare price.
A quote without a specification cannot be compared. We confirm thickness, coating, profile and packing before we send a price. This avoids disputes after the order.
How to Choose a Stone Coated Metal Roofing Supplier
Short answer: Choose the supplier who can prove its claims. Ask for documents, samples and a factory check.
Supplier Checklist
- Certifications: ask for CE, ISO 9001 or ASTM reports.
- Warranty: get the term and conditions in writing.
- Capacity: ask for monthly output in square meters.
- Lead time: ask for days, not “soon”.
- Samples: test color and finish before mass production.
- Third-party testing: request independent lab reports.
- Factory audit: arrange a video tour or on-site inspection.
- Packing: confirm pallets, crates and container loading plan.
A good supplier answers these questions with documents. A supplier who avoids them is a risk.
JCROOF manufactures stone coated metal roof tiles in five main profiles. We support small sample orders, document checks and video factory tours before bulk production.

Common Issues and How to Prevent Them
Stone coated roofing is not free of problems. Most come from specification or installation, not the concept.
| Issue | Likely cause | What to check |
|---|---|---|
| Granule loss | Weak bonding or low-grade resin | Granule adhesion test report |
| Corrosion at cut edges | Poor metal coating or bad detailing | Coating type, edge sealing guidance |
| Dents from hail | Thin steel in hail-prone areas | Steel thickness for your region |
| Algae or moss | Humid, shaded roofs | Cleaning plan, local conditions |
| Rain noise | Poor underlayment or bare decking | Installation method |
Large hail can damage any roof. If your market has frequent hail, ask for the thickness and any impact test results.
Frequently Asked Questions
Q: How long does stone coated metal roofing last? A: Many guides state 30 to 50 years with correct installation and maintenance. Your actual warranty term matters more than a general range.
Q: Can I order a small sample first? A: Yes. A sample lets you check color, granule finish and panel quality. Confirm the profile and finish before bulk production.
Q: Can it go over an old roof? A: Sometimes. Some systems can go over one layer of existing roofing. Local building codes and the condition of the deck decide this.
Q: What documents should I ask for? A: Ask for certification reports, test reports, the technical data sheet and the warranty terms.
Q: What is the lead time for a container order? A: It depends on the profile, color and order size.
