Advanced Residential Roof Systems

This Partnership for Advancing Technology in Housing (PATH) report outlines a research agenda for developing residential roof systems that serve multiple functions and improve performance over current systems. The scope of this agenda covers residential single-family type buildings, roofs of all ranges of pitch, and roof systems encompassing all components and subsystems from the top of the wall at the ceiling to the roof covering. In particular, five sets of strategies are detailed to achieve gains in (1) hazard mitigation, (2) energy performance of roofs, (3) safety and efficiency in roof system construction, (4) roof functionality, and (5) improving the environmental impact of roofs.
