Low-slope roofs with PVs tested for wind uplift resistance

Low-slope roofing systems that feature photovoltaic panels, pavers, and other applications have undergone testing to develop wind uplift standards by the National Research Council Canada and the Special Interest Group for Dynamic Evaluation of Roofing Systems. Tests showed air-sealed concrete roofs can withstand uplift better than steel-and-plywood systems, while winds can cause PV panels to destroy waterproof membranes. Research is also being done on modular green roofs to form wind uplift standards for them.
