Ludowici Roof Tile, LLC., based in New Lexington, Ohio, is an American manufacturer of clay roof tiles, floor tiles, and wall cladding. The company was established in 1888 with the formation of the Celadon Terra Cotta Company in Alfred, New York. It has created tile for many prominent buildings throughout the United States.

Roof tiles are overlapping tiles designed mainly to keep out precipitation such as rain or snow, and are traditionally made from locally available materials such as clay or slate. Later tiles have been made from materials such as concrete, and plastic.
