Roberts was closely involved in the restoration of Windsor Castle, a medieval castle and royal residence located in Windsor, Berkshire, England, notable for its long association with the British Royal Family and its architecture after its 1992 fire.
He was previously a director of Christie's, an art-business and a fine-arts auction house, and was the head of its Decorative Arts Department. His particular area of expertise is French and English furniture and interior decoration of the 18th and 19th centuries; he has written extensively on these subjects in Royal Collection exhibition catalogues and major journals.
