Vermont Unfading Gray

Vermont Unfading Gray


Vermont Unfading Gray slate is a medium-texture slate, usually with black markings. It typically will not experience much, if any, buff & brown weathering. The color resembles battleship gray and may have a slight green hue when wet. It is a great choice for a formal design where uniformity in overall color is desired, but has enough shading to show some texture and depth on the roof.
