No other roof has the elegance and durability of slate!
Slate has been acclaimed for generations as the ultimate roofing material. Slate is natural stone with a remarkable property: it can be split into thin tiles of uniform thickness. This is what made slate the most desirable roofing material for more than 1000 years! A slate roof, since it is stone, simply has no equal in durability. Its natural beauty sets it apart from any other roofing material, and each slate roof has its own unique character. You can enhance the aesthetic appearance of nearly any building with the wide variety of rich natural slate colors and slate textures that can be combined in nearly endless combinations.
The Greenstone Slate Company has been a leader in crafting Vermont roofing slate for well over half a century, and has shipped slate all over the world for residential and institutional 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.

Yes, there is a way to reduce the weight of a genuine slate roof. Slate roofs are noted for being heavier than other roofs — a trade-off for the durability, longevity and aesthetic value of a natural stone roof. However, advances in the materials and methods associated with slate roof installation has made it possible to reduce the overall roof weight by simply using less slate. Lower weight makes slate a very realistic alternative when replacing a cedar shake roof, for example, or in new construction when there is limited budget for the structural reinforcement required to support a traditional slate installation. In fact, the weight of a slate roof can now be brought down below 6 lbs /sq ft — a weight that most quality buildings can support. More about reducing the weight of a slate roof.
The SlateTec patented slate roofing system reduces the weight of a slate roof by applying their very rugged interlayment under the slate. Learn more about SlateTec and view installation videos.

Slate is metamorphic stone that was formed millions of years ago in various regions of the world, and it is not all the same. The geological conditions when slate was formed influence its strength, durability, and appearance. Fortunately, slate from each of these region has been independently tested for quality which has resulted in clear performance ratings. We are proud of the fact that all Greenstone Slate has been rated ASTM S1, the highest quality rating assigned to any slate.
