In this study, by investigating the roof of the houses in Banadkook-Dize village in Taft county (Yazd, Iran) from the appearance of the village, the reason of form changes and their method of construction have been examined. To do this, the history of the village was divided into four different era; the first era was when the village came into existence and the villagers used to live in the citadel; the second was when the citadel had no more capacity and the people went out of the citadel to construct buildings near it; the third was the constructions after the destructive flood of 1956 in the village; and the fourth one is the current construction status of the village. Except for the first period which the citadel is almost completely destroyed and no information is left, five houses were studied for each era throughout field study and an interview was conducted with the owners.
