Mission Tile

Monk and Nun

Monk and Nun, also known as pan and cover, mission tiling, Spanish tile, gutter tile, or barrel tile, is a style of arranging roof tiles, using semi-cylindrical tiles similar to imbrex and tegula, but instead of alternating rows of flat tiles (tegulae) and arched tiles (imbrices), both rows consist of the arched tile. The top row with the convex side facing up are the monk tiles while the bottom row with the convex side facing down are the nun tiles. Mortar is often used under the monk tile to firmly attach it to the nun tile, though this can lead to failure in areas with cold winters.

Tile

Tiles are usually thin, square rectangular coverings manufactured from hard-wearing material such as ceramic, stone, metal, baked clay, or even glass. They are generally fixed in place in an array to cover roofs, floors, walls, edges, or other objects such as tabletops. Alternatively, tile can sometimes refer to similar units made from lightweight materials such as perlite, wood, and mineral wool, typically used for wall and ceiling applications. In another sense, a tile is a construction tile or similar object, such as rectangular counters used in playing games. The word is derived from the French word tuile, which is, in turn, from the Latin word tegula, meaning a roof tile composed of fired clay, otherwise known as nga.
