Vermont Black and Gray/Black

Vermont Black and Gray/Black


Vermont Black and Gray/Black slate is a medium to heavy texture stone with a medium to dark gray color and darker, linear markings. This slate is separated into the darker (Vermont Black) and lighter (Gray/Black) to provide the desired depth of color. While this slate does not weather into a multicolor roof, you may get some bronzing in the lighter parts of the slate over time.
