An architectural tile is formed of a body portion having securing means extending therefrom. A plurality of tiles are secured together to form a roof or wall covering. The securing means include leg portions which are flexible and guide bars for directing securing means from facing tiles into interlocking positions. The legs are of sufficient length to provide flexibility and to prevent leakage of water into the gaps between adjacent lower tiles. Ridges extend from the lower surfaces of the body portions for spacing an overlapping tile from an overlapped tile to form a shadow line. The body portions may be flat or curved or a combination of flat and curved portions.
