Abstract
A major residential building complex with 1,725 apartments where two renovations of the roof systems and terraces have taken place has been surveyed during a period of more than 35 years. The building includes a large number of roof designs in the form of roof terraces, vegetative roof systems and ballasted roof systems. The roof design is of utmost importance for these buildings where the roof system is not visible and extra care must be taken to ensure watertightness and service life. This paper presents the experiences gained from the original roof systems and short-lived second roofs, as well as precautions taken to ensure better results during the latest refurbishment. One single faulty detail can spoil a project; therefore, it is crucial that all critical details are analyzed thoroughly during the design and well before launching any specification.
