Stone coated roofing sheets combine the durability of industrial metal roofing with the visual charm of traditional roofing materials. If you want a roof that can handle whatever challenges Mother Nature throws at it, without compromising on style, then stone-coated roofing sheets are the perfect choice.
In this blog, we’ll explore the following:
- An overview of metal roofing and its advantages.
- How stone-coated roofing sheets differ from industrial metal roofing.
- The manufacturing process of stone-coated roofing sheets.
What is Metal Roofing?
Metal roofing refers to a range of roofing materials made primarily from metal. These products offer durability, strength, and resistance to the elements, making them a popular choice for both residential and commercial properties.
The most common types of metal roofing products include:

Metal roofing offers numerous benefits due to its long lifespan, durability, low maintenance requirements, and high return on investment (ROI), including:
- A metal roof lasts 2 to 3 times longer than traditional roofing materials like asphalt, tile, and wood.
- Metal roofs are highly energy-efficient, potentially reducing cooling costs by up to 25%.
- A metal roof can lower homeowner’s insurance premiums by up to 35% (check with your local insurance provider for available discounts).
- A modern metal roof can increase home value by as much as 6%.
- Homeowners who renovate with metal roofing often recoup a significant portion of the roof’s initial cost. On average, homeowners can recover 85.9%, with homes in the Eastern states recouping up to 95.5%.
The high ROI of metal roofing is largely due to its exceptional durability, offering impressive features such as:
- The highest rating for hail impact resistance.
- The ability to withstand hurricane-force winds.
- The top rating for fire protection.
Metal roofing has been a dominant choice in the industrial sector for over a century. Warehouses, factories, and other industrial buildings have long relied on the unparalleled durability that metal roofing provides.
However, traditional metal roofing materials such as aluminum, copper, corrugated, and standing seam roofs often fall short when it comes to the aesthetic appeal and design flexibility needed for residential properties. This is particularly true for designs that include complex or classical architectural elements like cupolas, gables, towers, multiple valleys, and intricate facades, where large panel metal roofs may not fit the bill.
Stone-coated metal roofing solves this problem by combining the durability of industrial metal with the design versatility required for residential homes. Homeowners can enjoy the benefits of metal roofing without compromising on style. Here’s how.
How is Stone-Coated Metal Roofing Different from Metal Roofing?
Stone-coated metal roofing is crafted from steel sheets, which are then coated with stone granules.
The steel sheets provide the ideal foundation because they can be easily shaped into a wide range of forms. The stone-coating process allows for a broad selection of vibrant colors and textures, enabling the roofing to resemble traditional materials such as asphalt shingles, clay tiles, and wood shakes. This feature grants stone-coated metal roofing products, like RoofGlory Metal Roofing, exceptional design flexibility to suit any aesthetic.
The stone granules in these roofing products do more than just enhance design flexibility. They also offer unique additional advantages, such as:
- Enhanced Energy Efficiency: The infrared pigments in the stone coating boost the natural solar reflectance of the metal roof, improving energy efficiency. The U.S. Department of Energy has conducted studies to verify the thermal performance of RoofGlory’s stone-coated products.
- Noise Reduction: RoofGlory stone-coated metal roofing is naturally quiet in the rain, thanks to the sound-absorbing cushion created by the stone granules. There’s no need for extra soundproofing materials.
Let’s dive deeper into how the stone granules in stone-coated metal roofing are made.
The Stone-Coated Metal Roofing Manufacturing Process
RoofGlory’s stone-coated roofing products use roofing granules made from natural stone. The stone is mined from quarries, crushed, and screened to various sizes. These granules are applied and embedded in an acrylic base coat, forming a layer that provides maximum coverage for the roof panel surface.
Several factors are important when choosing the appropriate stone, including:
- Hardness
- Opacity to solar ultraviolet light
- Chemical and physical inertness to resist acid rain and leaching
- Durability against freeze/thaw and wet/dry cycles
- Minimal oxidation and rusting (low iron content)
- Low porosity
- Suitability for coating
- Particle shape
The stone granules achieve their vibrant colors through a process in which the stone particles are coated with a mixture of pigments, similar to paint. This mixture is baked onto the stones at high temperatures, resulting in a ceramic-like coating. The final color and appearance of the granules are determined by the pigments used.
Multiple color readings, using a spectrophotometer, are taken during the manufacturing process to ensure consistent color. Color fixation tests ensure that the pigmentation adheres properly, ensuring long-lasting color stability under intense solar UV exposure.
RoofGlory uses advanced computerized blending and application machinery to ensure high-quality stone coating in every roofing panel.
