Abstract:The research highlights several existing methods for flat roofing leakage detection. The majority of implemented leakage detection methods are inefficient active methods which require regular testing; passive methods, while more efficient, are costlier to implement. In the first section of the paper, these individual methods are highlighted and compared with one another. From this, several hypotheses about the behaviour of moisture within flat roofing insulation are formulated, and these are used to formulate several research questions. These research questions are used to design experiments to investigate these behaviours of roofing insulation further, and these experiments and their findings are presented in the next section. From these experimental results, a model is proposed which aims to use the findings to passively locate roofing leakages more effectively and in a more cost-efficient manner, based predominantly around the behaviours in change of humidity within an insulation block. Conclusions are then drawn, and further works required to fully implement this model, as well as any possible improvements suggested, are then discussed. It is hoped the research can contribute towards a greater understanding of the behaviours of roofing insulation, and assist with the development of a more cost-efficient and accurate passive leakage detection system.
