Greenstone Slate

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.


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.
