    Abstract: High wind-induced suctions cause significant damage in traditional roofing systems, leading to subsequent rain intrusion and loss of interior contents. Damages include, among others, failure of tiles or shingles and in many roofing systems are related to workmanship-related issues, such as inadequate spacing of nails or poor application of foam adhesive. This paper proposes a new composite roofing system, which consists of large precast concrete structural panels designed to replicate the architectural shape of high-profile roof tiles. The system allows the components and cladding (C&C), usually placed onto the structure, to be incorporated into the main wind force resisting system (MWFRS). The roofing panels, therefore, serve both as a structural system and as an architecturally pleasing building envelope. As a first step toward the full development of the proposed system, full-scale tests were performed to evaluate its system-level structural performance, including its connections. The results are used to predict the system’s strength and serviceability capabilities. Tests under a combination of loading scenarios simulating high wind-induced pressures indicated that the structure performed well under extreme wind-induced loading. The test results were used to develop tables containing design data for the new roofing system for buildings located in various geographical regions. In addition, a preliminary cost estimate was performed. The paper lists recommendations for future research, including testing of the proposed system aimed at developing and assessing the system’s performance under wind-driven rain, its energy efficiency, and its noise-reduction properties; performing detailed and comprehensive cost estimates; and exploring the potential of alternative roof shapes and configurations.
