ANSI SPRI WD-1; wind design

SPRI recently published ANSI/SPRI WD-1, "Wind Design Practice for Roofing Assemblies." This standard provides a recognized consensus-developed methodology for designing wind-uplift resistances for low-slope built-up, polymer-modified bitumen and single-ply membrane roof systems that do not rely on aggregate or paver ballast to provide their wind resistance.
