Stone-Coated vs. Smooth Metal Roofing Panels: Which is Better for Your Home in Ontario?

When it comes to choosing a premium roofing solution in Ontario, homeowners often face one key decision: Stone-coated metal roofing panels vs. smooth metal panels. At Gerard Canada, we offer both types—each with its own strengths. But which one is the better fit for your home? Let’s explore the differences and advantages of each to help you make an informed decision.

What Are Stone-Coated Metal Panels?

Stone-coated metal roofing panels are made from high-grade steel and coated with natural stone granules. These granules are bonded to the panel with a durable acrylic film, offering an elegant, textured finish that mimics the look of traditional roofing materials like asphalt shingles, slate, or tile—but with the performance and longevity of metal.

What Are Smooth Metal Panels?

Our smooth metal panels are crafted from the same high-quality steel and built using the same panel sizes and stamped profiles as our stone-coated versions. However, instead of the stone granules, they feature a sleek, baked-on finish for a more modern, minimalist appearance. These panels still deliver all the structural benefits and come with the same 50-year transferable warranty as our stone-coated options.

Key Differences Between Stone-Coated and Smooth Metal Panels

1. Aesthetics & Curb Appeal

• Stone-Coated Panels: Offer a textured, traditional look that blends beautifully with heritage-style and classic homes. Great for those who want the look of shingles or slate but with metal strength.

• Smooth Panels: Provide a clean, contemporary look. Ideal for modern homes or homeowners seeking a low-profile, minimalist design.

2. Surface Finish

• Stone-Coated Panels: The granulated surface helps diffuse sunlight, reduce glare, and hide dirt and imperfections more easily.

• Smooth Panels: Easier to clean but may show dirt, scratches, and debris more noticeably due to their flat surface.

3. Energy Efficiency

Both panel types are energy-efficient and reflect solar heat, helping to reduce cooling costs in the summer. The stone-coated surface offers added insulation, while smooth panels reflect UV rays efficiently.

4. Durability & Performance

• Both styles are engineered to handle extreme Canadian weather—wind, snow, hail, and heavy rain.

• Both come with a 50-year transferable product warranty and a 12-year workmanship warranty, providing long-term peace of mind and increased resale value.

5. Weight & Installation

• Both panels are lightweight and actually lighter than most shingle systems. They do not require strapping and can often be installed over existing roofs, depending on condition.

• Installation time is similar, and both systems benefit from the expertise of our experienced crews.

6. Cost Comparison

• Stone-coated panels are slightly more expensive due to the added materials and processing involved in applying the stone granules.

• Smooth panels offer a more budget-friendly option while still providing the same structural integrity and warranty coverage.

Which Roofing Panel Should You Choose?

If you’re looking for a classic, textured look with the charm of natural materials, stone-coated metal roofing is the way to go. If you prefer a sleek, modern finish and want the same strength and protection at a slightly lower cost, our smooth metal panels are a fantastic option.

Either way, you’re getting one of the best metal roofing systems in Canada—with unmatched warranties and long-term value.
