What Evergreen Slate Co does
Evergreen Slate Company, Inc. is a privately held New York corporation founded in 1916 and headquartered in Middle Granville, NY, that produces and supplies natural Vermont roofing slate for residential, institutional, and commercial buildings. The company self-describes as the largest producer and supplier of roofing slate in the United States, sourcing material from approximately two dozen quarries and offering 14 slate colors and three proprietary pre-selected blends (Manor, Imperial, Vermont Splendor) in varied sizes, thicknesses, and textures, all conforming to ASTM C406-00 Grade S1. It also markets installation tools and accessories (slate cutters, hammers, rippers, hooks, nails, the Hinged Ridge Vent System), publishes The Slate Book as an installation reference, and provides architectural services including CAD drawings and quantity take-offs for complex applications.
The business serves architects, general contractors, roofing contractors, luxury homeowners, and institutions (universities, churches, libraries, government buildings). Its go-to-market combines a two-person direct field sales team (Phil Prehoda and VP & Sales Manager Mike Flower) covering all US states and international territories, with a broad distributor channel of 25+ national and regional building materials wholesalers including ABC Supply Co., Beacon Roofing Supply, and Allied Building Products Corp. It supports specification-stage demand through AIA-registered two-day continuing education programs and joint educational events with Indiana Limestone Company. Revenue mechanics are one-time product sales priced per square (e.g., $429-$655 per square on Vermont Shadow Blend), with hardware sales of tools and accessories and professional services for architectural support as supplementary streams.
Evergreen has obtained Miami-Dade County product approval (#FL8802), enabling specification in hurricane-zone Florida, and has documented installations at Johns Hopkins Medical Center, Cambridge and Oxford universities, Cobh Cathedral, the British Ambassador Residence in Jakarta, and high-profile US residences including the Walt Disney, Rockefeller, and Heinz estates. Operations have been consolidated at a single Middle Granville yard, and the company operates with a small headcount of 11-50 employees, with no disclosed funding rounds, M&A activity, or external ownership.
