This study explores the application of innovative roofing technologies, such as aluminum and ETFE (Ethylene Tetrafluoroethylene), in the context of cultural heritage conservation at the Convent of Santa Maria di Costantinopoli. The research focuses on the preservation and functional adaptation of historic structures, highlighting how the use of modern materials can enhance aesthetics, thermal performance, and structural stability without compromising the original integrity. Through detailed analysis of material degradation and intervention strategies, the paper illustrates the advantages and challenges of integrating contemporary solutions into historical contexts. The case study of the Convent offers a replicable model for careful and innovative conservation, proposing a balance between respect for the past and adoption of technological advancements for the future of architectural preservation.
