Due to the employment opportunities in the cities after the Industrial Revolution, there has been intense migration from rural to urban areas. There has been a rapid construction process in order to meet the housing needs of the increasing population in the cities. Unplanned urban development has led to the destruction of green areas. As a solution to this problem, green roof applications in urban centers have gained popularity. Urbanization, which has been realized within the framework of the principles of sustainable urban development, has been a crucial requirement for the physical and mental health of future generations.
