In this study we investigate the construction and maintenance of CHOGA roofs in Korean Peninsula. The constitution of the roofs may contain soil or may not contain soil, while the materials used in different regions may be slightly different. For maintaining the roofs, reproofing is performed every one, two or three years, with many different kinds of construction methods pertaining to different regions. However, with the introduction of modern technologies and materials for the construction and maintenance of the roofs, the roofs are getting more different from the genuine roofs. The purpose of this study is to identify the regionalization of the construction methods of CHOGA roofs in Korean Peninsula, to record the reproofing techniques for maintenance, and to keep track of the regional characteristics of the roofs so as to find out the future direction of maintaining CHOGA.
