Roofing tiles were made from clay in the mold called Mogol or Wabeop, by baking them in a kiln.
Tiles were used to block rain and snow, to let waters flow on the ground preventing erosion of the building, and to decorate the building.
Using roofing tiles on a wooden building was a tradition in the traditional Asia.
Kinds of roofing tiles were various according to the location of using, but the basic kinds were Su-kiwa(male tile), Am-kiwa(female tile), Mangwa which decorated ridges,
Am-makse(female block), and Su-makse(male block).
