American Slate Company

What American Slate Company does

American Slate Company, founded in 1979 and now operating under the trade name Vermont Slate Co., is a U.S. wholesale distributor of natural slate roofing, cladding, and related stone covering products. Its operations are headquartered at 6001 Chatham Center Drive, Suite 150, Savannah, Georgia, with a listed contact in Fullerton, California. The company sources natural slate from global quarries — including the CUPA range imported via its partner CUPA Group and domestic Vermont sources — and addresses three primary customer segments: professional roofing contractors, architects and design professionals, and building professionals and general contractors.

The product portfolio is organized around a multi-SKU slate catalog and two sub-brands. Roofing slates include the CUPA series (CUPA 14, CUPA 50, CUPA 7, CUPA 3) and proprietary named SKUs such as Andes Cliff, Vermont Unfading Gray/Green, Sierra Pass, Pike's Point, McKinley Heights, Vermont Purple, Appalachian Ascent, Fairweather Way, and Riverstone. Sub-brands include Readyslate, a ready-to-install roofing system, and Cupaclad, a rainscreen/clip cladding system for exterior walls. The company pairs its catalog with technical resources (datasheets, installation guides, certifications, technical drawings) and an AIA-approved continuing education course for architects, supported by membership in the National Slate Association, the Slate Roofing Contractors Association of North America, and the Vermont Slate Quarry Association.

Revenue is generated through a direct sales model in which project-specific quotations are provided on request, indicating a B2B, project-driven sales cycle rather than a published price list or transactional e-commerce channel. Marketing is limited to a Facebook page, a monthly newsletter, an educational content library, and association-based networking. Headcount is in the 11–50 range, and the company operates privately with no disclosed funding, revenue figures, leadership team, or capital structure.
