70 mile per hour winds caused extensive damage in Quincy, Illinois: Trees uprooted, gas lines broken,
impassible roads, and roofs damaged. On a local shopping center, roofs were damaged, stone coping
caps were blown off and HVAC units were damaged.
However, a 600 square (60,000 sq. ft.) VADA Vented Roof, on a 40’ tall building was completely unharmed. Strategically placed VADA Vents create vacuum, holding the roofing membrane in place. VADA Vents, in conjunction with an engineered perimeter, create a winning combination. This patented and patent pending technology has never been damaged by a wind event in over 28 years of real world applications.
