The Slate Roofing Contractors Association of North America, Inc., was originally formed as an unincorporated association in Pennsylvania in March of 2005 to fill a void in the United States roofing trades. Professional slate roofing contractors had little representation in the U.S. roofing trades industry, with 95% of all new American roofing being something other than slate. The SRCA incorporated as a non-profit trade association on December13, 2007, as the Slate Roofing Contractors Association of North America, Inc. The SRCA has published natural quarried slate roofing installation guidelines and is developing training programs. We share our knowledge and comaraderie at scheduled conferences, and volunteer labor and materials at non-SRCA conferences and workshops. We organize slate roofing professionals and other contractors and make them available to the public via our membership listings, source lists, and Contractor Profiles
