Dorset Blend Roofing

Dorset Blend Roofing Slate is a popular Vermont roofing material. Because of its performance qualities, unique blend of colors and rich texture, architects repeatedly specify this natural Vermont slate for institutional and residential roofing projects. The image on the left is of newly-quarried material; please be advised this roofing slate will “weather”, meaning it will take on brownish tones over time, “softening” the overall appearance. Dorset Blend Roofing Slate is available in many sizes and thicknesses.
