Vermont Natural Roofing Slate in a Myriad of Colors

Evergreen Slate is the largest producer and supplier of roofing slate in the United States. Since 1916, the company has taken pride in providing its customers with high-quality slate products and excellent customer service, as the leader in the slate roofing industry.

The thousands of roofs we’ve provided to fine homes, churches, libraries, government buildings and universities for almost 90 years are a testament to our role as the premier roofing slate provider.


roofing slate Evergreen has developed several distinctive blends of color toafford the ultimate in slate roof applications. These are blends that are readily available and have been put together specifically to attain the curb appeal that is desired for the most prestigious of projects.


Unfading* Mottled Green and Purple - A Vermont slate of unusual color, ranging in soft shades of purple and green in each piece, from purple predominating to green predominating.

Unfading* Red - A hard-vein red slate similar in color to Spanish mission tile.

Canadian Black -

Mottled Gray-Black - Grayish background with mottled shades of darker Gray-Black, some weathering can occur. Sometimes called "Strata Gray."

Royal Purple - A beautiful, nearly clear, dark purple slate. Some pieces may have small markings of green. Provides a contrasting roof for walls of light shades, or a harmonizing roof for brick walls. Some weathering to buffs can occur.

Semi-Weathering Gray-Green - This is an exceedingly strong and tough. Grayish-Green in color when quarried, this slate can gradually change to softer tones after exposure to the weather, adding variety and interest to the roof, but in no way affecting their durability. This slate blends well with any type of stone or frame structure and is also used as the basic percentage, usually 50%, in roofs where several colors are mixed.

Semi-Weathering Gray - A traditional slate-gray color ranging from a clear appearance to having small black markings. Weathering of 15% – 20%, to buffs and tans can be expected.

Unfading* Green - A Vermont favorite, this slate is green with shades varying slightly.

Unfading* Gray - A battleship gray slate with some clouded grayer markings.

Vermont Black - One of our most popular colors. Primarily unfading but some weathering can occur, creating an interesting blend of dark gray tones, adding character to roofs of all styles.

Variegated Purple - A purple slate varying in shade from purple predominating to green predominating. A semi-weathering type slate where approximately 15% will weather to buffs and tans.

* All natural slate products may change in color. Those slates in which the color changes but slightly are classed as "Permanent" or "Unfading". (National Slate Association: January 1925)

Samples of all color choices are available through our sales office.
