We are a fully insured company specializing in historic restoration and preservation of slate and copper roofs. We also do ornamental slate work and new slate roof installations. We are located in western, Pennsylvania and work in that general area, but we do travel over state lines on occasion. We offer nation wide consultation services and training in slate roof restoration, installation and copper flashing techniques.  

Our family's passion for slate began in 1968 when Joseph Jenkins first set foot on a slate roof. Since that moment, we've contributed greatly to the slate industry due to the publication of The Slate Roof Bible, the formation of the Slate Roofing Contractors Association of North America, the creation of the largest Traditional Roofing Store in the world, and the publication of the Traditional Roofing Magazine

The Jenkins family's dedication to the slate industry shines through in our quality of work. We at Jenkins Slate Masters, Inc. strive for perfection and thoroughly enjoy working with slate and copper.
