According to some studies, flat roofs are one of the construction elements that most frequently suffer from damage and anomalies. It is important to carry out a verification of the execution processes of waterproofing membranes to reduce the number of failures as much as possible and prevent future associated damages. This paper details the 47 evaluation parameters that were applied to 61 construction projects, rated in terms of their quality in five levels of importance of the deficiencies, based on the supervision performed by quality control entities during the execution of the works. The results numerically demonstrate the importance of prior supervision of project design to produce more satisfactory results and reduce the probability of problems in the future. The most common problems in flat roofs with bituminous membranes are identified and rated, of which issues concerning the tail-ends with peripheral elements stand out.
