Purple Roofing Slate was the first Vermont roofing slate to be produced commercially with operations starting in 1839. Its deep, rich plum color holds a special appeal and it was frequently used on church roofs during the past two centuries. Because of its superior performance, rich color and natural texture, architects repeatedly specify this natural Vermont slate for institutional, commercial and residential roofing projects. Purple Roofing Slate is appropriate for both traditional and contemporary architecture. The purple color will vary in shade and may contain green markings. Purple Roofing Slate can “weather”, meaning it will take on brownish tones over time when used outside. It is available in many sizes and thicknesses. It is a relatively rare slate.
