Our stone is worked only by Greenstone trained craftsmen. Our production facilities are constantly updated and expanded. This has lead Greenstone Slate® to become a principal producer of colored slate roofing. We deliver consistently high quality product, with excellence in service and installation support, and competitive, direct pricing—for the highest value possible in a slate roof.

A distinctive slate with an overall grayish background and mottled with various shades of darker gray/black giving it excellent character. Its textures contribute to its character and will display some weathering.
