Overview: 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.

The Nu-lok™ roofing system is a new method for fastening slate to a roof that significantly reduces overall roof weight by more efficiently using the slate. Its patented batten and Link Channel™ design that utilizes galvanized and stainless steel to create a grid that holds the slates securely in place. The Nu-lok™ system and slate weighs less than six pounds per square foot, which is within the design parameters of most structures.
