Sometimes known in North America as a "French profile", the French tiles offered by Northern Roof Tiles are interlocking and available in attractive neutral colors.
"Marseille tile" was based on a design created by the French Gilardoni Brothers in 1850. Later a group of manufacturers in Marseille, France – refined the original design and commercialized large numbers of the new interlocking tile. The tiles were enormously popular outside of France, and were exported all over the world. Gray clay was primarily used in Europe and red terracotta in Latin American and the colonies.
