The Slate Roofing Contractors Association of North America, Inc. was originally formed in Pennsylvania in 2005, then incorporated as a non-profit trade association in 2008, with members on three continents. The SRCA is a participating member of the International Federation for the Roofing Trades based in Germany, and an Affiliate Member of the National Roofing Contractors Association. The SRCA has published natural quarried slate roofing installation guidelines (in both English and Spanish), freely available to the public, and is developing slate roof installation, repair, restoration, flashing, and other training programs. We share our knowledge and camaraderie at scheduled conferences, and we volunteer labor and materials at non-SRCA conferences, such as the International Preservation Trades Workshops, where we installed new slate roofs in St. Clairsville, Ohio and in Frankfurt, Kentucky. We organize slate roofing professionals and other contractors and make them available to the public via our Membership Listings, Contractor Directory, and Source Lists.
