Gray Green (Semi-Weathering) Slate is one of the most iconic Vermont slate varieties, with a legacy dating back to the mid-19th century. This slate features tones ranging from medium gray to light green, with a medium-smooth texture. It is available in a wide range of sizes and thicknesses to accommodate various architectural applications.

Renowned for its strength and durability, Gray Green Slate offers a lifespan of over 100 years and is straightforward to install. When freshly quarried, it presents a distinctive gray-green tone. Over time, approximately 20%–40% of the tiles may weather naturally, developing rich hues of brown, pink, and buff—adding character and a timeless patina seen on historic rooftops across the Northeast.

Custom lengths and thicknesses are available. This product also meets Solar Reflectance Index (SRI) requirements for Title 24 Cool Roof compliance.
