ABSTRACT:
An apparatus attached to the roof perimeter to mitigate wind-generated vortices and uplift loads on the roof perimeter area of a building, applicable for both new constructions and retrofits of existing buildings. The apparatus comprises at least one face portion having face perforation and/or edge serration for increasing small-scale turbulence entrainment, equalizing pressure and disorganizing edge shear layer vorticity, and thus disrupting vortex formation. A roof edge vortex suppressor is preferably mounted along the entire circumference of a roof perimeter.
