ABSTRACT
ABSTRACT This study proposes a systemic methodology to predict the service life of pitched roofs clad with ceramic tiles, considering various steps: i) inspection and diagnosis of the roofs, in service conditions, through visual inspections; ii) mathematical modelling of the sample obtained during fieldwork; iii) identification of the degradation factors that influence the deterioration of ceramic tiles on pitched roofs'; and iv) estimation of their service life. For that purpose, a sample of 85 buildings and 146 claddings, with a total area of 43.992 m2, were analysed. The service life prediction model proposed led to coherent and seemingly accurate results, providing crucial information for the adequate definition of maintenance strategies, thus optimizing funds and resources. The data related with the service life of the roof systems are fundamental for the development of Life Cycle Assessment (LCA) and Life Cycle Cost (LCC) tools, promoting the adoption of more sustainable solutions during the life cycle of buildings.
