AbstractWaterproof membrane type roofing systems have not always given the performance that might have been expected of them, even when construction conditions and workmanship have been good. Analysis of all the factors that cause failure indicates a need for a building science approach to the design of roofing sytems, with some arrangement of the components different from the conventional. The protected membrane system has been promoted by the Division of Building Research for some years. This paper describes this approach to roofing as it has been applied to roofs at the University of Marburg in Western Germany. The term " inverted" or "upside down" has sometimes been used to describe protected membrane roofs, with all the bad connotations that this invokes. The author tries to indicate that they should be called "right-side-up" rather than "inverted".
