A critical aspect in wind load analysis is determining and applying the correct factor of safety during the calculation process. Make sure you attend this session from The Single Ply Roofing Association (SPRA) for guidance on the use of factors of safety (FoS’s) and how they are applied to the different single ply application methods incorporating different deck and system types including; Mechanically fastened – design criteria for membrane and insulation fasteners, fastener pattern and pull out requirements. Adhered – maximum design resistance, FoS, testing, refurbishment and bonded overlays. Ballasted – restrictions, ballast type and inverted and green roofs.
