Natural stone slate roofing has been used for centuries and some slate roofs are, in fact, over a century old. Slate roofs are typically installed with all copper flashing materials and are built to last the life of the structure without requiring replacement. Stone slate roofing has a higher upfront cost, but for long-term value for its architectural beauty and longevity are second to none. A variety of sizes, thicknesses and colors are available to meet your design needs. Slate roofs can make your roofing project stand out, especially when used in conjunction with copper dormers and copper accent roofs.
