KRS Stone Coated Metal Roof Tile / steel roofing tile is made from a corrosion resistant metal and coated with stone chips that are attached to the steel with an acrylic adhesive layer. Their goal has been for a more durable roof that still retains the aesthetic advantages of a more traditional roofing material such as clay tile or wood shakes.
Stone chip coated metal tiles typically are attached with the use of corrosion resistant screws after they have interlocked with all the adjoining tiles they abut and overlap. Foot traffic should be held to a minimum so as not to wear away the protective stone surfaces or dislodge the interlocking laps that allow them to withstand the effects of storms.
Another reason why these steel shingles are coated with stone is so that they are not loud during rain storms. This coating also directly protects the steels from suffering from wear and tear. If you live in an area that is no stranger to heavy thunderstorms
