Our quarries in Vermont have, for over a century, produced an exceptionally fine quality stone for roofing slate. High quality stone is just the beginning, however. 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.
