Riverhead Building Supply was founded in 1948 as one location serving the Riverhead, New York area. As the post-war baby boom got underway and people began spreading out to what are now the suburbs on Long Island, home building became a thriving business. At the present time there are six hundred employees working at Riverhead Building Supply in New York and Rhode Island, and we are all grateful for the family business that created our jobs today. Riverhead Building Supply is still family-run, now in its third generation of ownership, and continues to play an active role in building the local community.
