We've used the Eco-Fasten base plates on a variety of flat roofs including rolled asphaltic and TPO with appropriate flashings based on the roof type. We've attached in a variety of ways including metal roofs and direct to wood decking, but plywood, not OSB. And, we've done this with up to 160 mph ultimate design wind speed (ASCE 7-10). Because of the number of fasteners per attachment point, even OSB should provide enough pull-out strength to meet your engineering requirements.
