What is a Stone Coated Roof made of?

As mentioned, stone-coated metal roofing has multiple layers of coating. It is made with a high-strength steel material as its base and is then coated with multiple layers of protective materials, each one serving a different purpose:

  • Clear Acrylic Overglaze: provides waterproofing for the internal layers and base while improving bonding strength and color brightness.
  • Colored Stone Layer: protects from ultraviolet rays, reduces rain noise, and improves roof aesthetics.
  • Base Coat: strengthens the internal structure of the roof tile by ensuring strong adhesion of top and bottom layers.
  • Protective Coat: protects the zinc aluminum coating and enhances the paint’s bonding with the steel.
  • Zinc Aluminum Coating: protects the steel base from heat reflectivity and corrosion. Applied on the top and bottom of the steel base, thus adding another layer.
  • Protective Coat: protects the zinc aluminum coating and enhances the paint’s adhesion.

How is Stone-Coated Roof Made?

The foundation of a durable stone-coated roof tile is a high-strength steel. The process begins with stamping each metal sheet to form the different tile designs.

Each sheet then goes through different sections where it is sprayed with a layer of protective coating. The first layer sprayed on both the top and bottom is the zinc aluminum coating. Followed by the protective coat for the bottom of the tile.

On top of the tile, which will be exposed to the seasons, the protective coat, base coat, colored stone layer, and clear acrylic overglaze follow.

After the layers have been set and dried, the roof tiles are ready for installation.
