No other roofing material has the natural beauty and durability of slate!

Slate has been acclaimed for generations as the ultimate roofing material. It is natural stone that has the remarkable ability to be manufactured into thin tiles of uniform thickness. A slate roof simply has no equal in durability and natural beauty. Slate enhances the aesthetic design of nearly any building with its variety of rich natural slate colors and slate textures. There are many benefits to a slate roof from longevity and appearance to energy conservation. Greenstone has been a leader in crafting Vermont roofing slate for well over half a century, and has shipped product nationwide for residential and institutional slate projects. We invite architects, contractors, project managers and property owners to contact us with any question you might have about slate or to get a quote.

Vermont Slate is nature’s best slate!


From color to texture to durability, Vermont slate exhibits the best characteristics of slate. Slate is a metamorphic stone and is essentially laminated rock -- which is why it has the ability to be split into slate tiles. The geological conditions in the Vermont region when its slate was formed resulted in some of the world's strongest, highest density slate. In fact, Greenstone's slate comes with a 100 year warranty* -- a warranty that no other roofing material comes close to matching (*ask us for our detailed warranty statement).

Slate outperforms all man-made roofing materials

Advanced materials technology has generated some new roofing materials over the years, but slate remains the clear leader in creating the world's longest lasting and most trouble-free roofing material. It is the standard by which all others are compared.
