Stone-Coated Steel roofing material is a relatively newer roofing material that is made of a steel core, coated with a layer of Zinc-aluminum alloy, which then gets covered with an acrylic resin bonded stone chip layer. Two of the brands that we suggest for homeowners are Decra and WestLake Royal Roofing. Stone-coated steel products give the homeowner the ability to have an aesthetic similar to that of a shingle roof, while also capturing the durability of a metal roofing system. Although stone-coated steel is a great residential roof option, we believe there are comparable roofing systems, such as composite, that have an edge when it comes to longevity, durability, and aesthetics.
