Manufacturing process of roof-tile is wholly done in 4 main steps. The process start from choosing material of roof-tile that consist of clay and sand with ratio 4:1 (4 for clay and 1 for sand). Both of materials are mixed with water using cement mixer for about 1 day. After mixed, the compound is dried up with wind as long as 1 day up to thick. The thick compound is mixed again using cement mixer for 1 day, then it is dried up again by wind for 1 day. From the last mixing, The compound is molded using press machine.
