National Slate Association

The mission of the National Slate Association is to establish a material and installation standard for, and promotion of, natural roofing slate in North America. The association, which started in 1922 and was reformed in 2002, spans quarriers, contractors, architects, consultants, and distributors with a connection to natural slate. Primary goals of the association are to keep members updated with slate relevant information, give access to the most experienced resources the industry offers, and to promote the education of slate to future generations. If you’re looking to prosper in the slate industry, this association is your key.
