Abstract: The development of building construction in Indonesia is experiencing rapid development. In 2018, the total construction projects are predicted to increase by 3% compared to 2017. The concept of building high-rise buildings now uses the concept of green building. Where in the use of materials must be according to the approval of a green building consultant. This study uses roof covering material with solar panels, using these materials project planning becomes overbudget. Overbudget that occurs when planning with the green building concept is 15% of the initial contract. Therefore, the researcher will discuss the factors that influence the cost efficiency of the roof cover work of high-rise buildings. Processing data using SPSS tools (Statistical Package for Social Sciences). From this data processor with SPSS, there were 10 factors that caused the overbudget of roof cover work on the construction of high-rise buildings using wrong estimation techniques, complicated development requirements, inadequate project funding, not taking into account unexpected costs, inaccurate estimation of costs, data and incomplete project information, material selection according to work drawings, owner changes to design changes when construction is underway, lack of coordination between construction manager - planner and estimated cost of building high-rise buildings. For this reason, look for factors that cause roof cover work in the construction of high-rise buildings.
