Maintenance of Painted Steel Sheet Roofs

Painted steel sheet is a common roofing material for historical buildings, causing costly annual maintenance. Relevant recommendations and guidelines for maintaining in-situ and factory painted sheets are deficient from a conservation point of view. This project aim to assess materials and methods for maintenance and restoration of steel sheet roofs on historic buildings, and develope models to bridge the gap between research and practice and to balance technical, economic, environmental, and historical values. The empirical material for the research consists of practice case studies of treatments of steel sheet roofing, interviews with stakeholders, assessment of instructions from steel sheet and paint system suppliers but also property analysis of paint and metal sheets.
