The National Slate Association was first established in 1922 by slate quarriers. The goal was to promote the use of slate for roofing and structural applications. The standards set for slate and its installation are still adhered to today. Shortly after its formation, the organization became inactive due to lack of cohesion in the industry. However, its primary publication, Slate Roofs, remained a valuable resource, continuing to be reprinted and used throughout the quarrying, construction and design communities.
In January 2002, a historic meeting took place in Saratoga Springs, New York. A steering committee of producers, roofing contractors, architects, building owners, and other interested parties convened to revitalize the National Slate Association. Inspiration for the meeting came from Dave Leeland, Bill Marcum, Martech Associates, and Brian Stearns, et al., authors of The Slate Book, who sensed a growing interest in improving the industry. Bill Marcum chaired the meeting. The event was attended by Dave Leeland, Matt Millen, Doug Cochran, John Conlon, Pete Papay, and Jonathan Hill, all NSA Board members; Nancy Turner of U.S. Quarried Slate; Jim Gibbs, Pat Rudder, and Jim Constantine, all from Cornell University; John Meyer of Vermont Slate & Copper; Steve Taran of Taran Bros., Inc.; Norman Farrell of the Farrell Group; Pete Tatko of Sheldon Slate Products; Stuart Matthews of Northern Roof Tile; Richard Boyle of Evergreen Slate Company; Craig Markcrow of Vermont Structural Slate; Shawn and Dave Camara of Camara Slate; Ken Lerch of the Structural Slate Company; Chuck Smid and Clay Heald of New England Slate; and Joe Jenkins of Jenkins Slate Roofing Services. Just three months later, the National Slate Association was re-established as a non-profit, interdisciplinary, membership organization. The newly formed Board of Directors quickly grew from three, to six, to nine, with members from across the nation representing each of the key industries with a keen interest in slate roofing. Today, the National Slate Association is dedicated to promoting excellence through the development and dissemination of technical information, standards, and educational resources for the slate industry.
