It used to be that there were only a couple of types of metal roofing - corrugated metal, which has certainly improved over time but aesthetically has always been limited in options, or the much more costly copper cladding.
The latest product - stone coated metal roofing. Stone coated steel roofing is combined with the look of tile, shake or shingle or other types to give a strong, durable roof along with fantastic good looks. Whatever the style of your home or property, you will likely be able to find a metal roofing product to match your needs.

5 Reasons You Should Switch to a Stone-Coated Metal Roof
When you look at replacing your roof, you most probably consider traditional materials like shingles or tiles before anything else. Most of us don't even think about metal as a roofing material, though it has significant advantages over other materials.
1. Energy Efficient
2. Durable and long lasting
3. Low Maintenance
4. Long Lifespan
5. Wide Range of Styles
Project and Customer Praise
In general, there're 3 main parts of raw material contents:
1.Stone Chips ( Beautiful look, effective heat / UV resistant, noise reduction, anti-slip and etc features)
2.Galvalume Steel Plate ( Eco-friendly and recyable material, strong, light-weight, anti-corrosion, waterproof)
3.Acrylic Glue ( Premium sealing performance, strong adhesion, anti-algae)
1.Stone Chips - Why SANGOBUILD stone coated Roof Not FADED, not what you Think!
The other chip is sintered stone chips; it is the most advanced technology of the chips for stone coated roofing sheets. Sintering is the process of compacting and forming a solid mass of material by heat or pressure without melting it to the point of liquefaction. Sintered stone gives a guarantee of beyond 20 years on color retention. We also offer CL Rocks from French; We offer a guarantee of at least 20 years no fading, no color change.
2.Galvalume Steel - Strong the stone coated steel roofing sheets
Coating composition is 55% aluminum in weight ratio (80% surface volume ratio), 43.4% zinc, and 1.6% silicon. All Sangobuild® roof products are manufactured from alu-zinc steel which has shown in tests to last 6-9 times longer than ordinary galvanized steel roofing products. This is achieved by protecting the steel core with zinc, which is itself protected by an aluminium barrier. (It's not PPGI Galvalnized, but PPGL Galvalume, which is more durable with extreme weather condititons resistances)
3.Acrylic Glue
You may use the best stone chips in the world but if your adhesive is weak, you stand no chance. Your stone chips will definitely flake off.
Sangobuild's acrylic coat can remain a class apart from all competition. If the acrylic coat is too thin, it won't adhere as well.
The key property required of any roof coating material is durability. Durability implies resistance to the effects of UV degradation from the sun.
