Pathology, diagnosis and repair of pitched roofs with ceramic tiles: Statistical characterisation and lessons learned from inspections

This paper presents an expert-knowledge inspection and diagnosis system for pitched roofs with ceramic tiles and reports a statistical characterisation of the pathology of 62 roofs. It also identifies the diagnosis methods that may be used to characterise the anomalies and confirm their most probable causes, as well as the best repair techniques. A detailed correlation between anomalies and causes is also established. For the first time in the literature the pathologies of ceramic tile pitched roofs are characterised using quantitative indicators based on a statistically significant sample.
