Abstract
This paper presents an overview of observed distresses on low slope roofing systems collected for the Building envelope Life cycle asset management (BELCAM) project. The data include over 14,000 visibl3 distresses from 600 roofs from seven different climaticregions across Canada. The distresses encountered for built up roofs, modified bituminous roofs and a limited number of single ply roofoing systems are examined relative to climatic region, roof age, condition, and material type. Cross population samples of the data set are presented. The examination of this data set provides insight into the potential distresses found on existing roofs managed by building owners in Canada. These distreses are used to determine the condition of existing roofs for the BELCAM project.
