Since 1984, A.C.I. has installed large commercial industrial roofs across the United States.  We have installed watertight roofs from Seattle to Miami, and countless cities and towns in between.  A.C.I. began installing active vented roof systems in 1987. 

​

We found that the two existing vented roof systems at the time were perfect if all conditions were perfect - if the air seal was perfect and the roof was never punctured. The “margin of error” for the vented roof accepted norm was quite small, and a little wind infiltration would wreak havoc. As we continued to observe vented roof systems, we realized that the practice of venting the wind vortex of a building, which had been accepted for so long, was wrong. Hence, A.C.I. founders coined the phrase: “Don’t Vent the Vortex.”

​

 A.C.I. uses our patented design. We don’t vent the vortex. Instead we adhere and fasten the entire ASCE7 perimeter area.  So, after decades of real world roofing experience, this is how the VADA Vented Roof System was born (Vent Assisted Design Assembly).  We hold 3 U.S. patents on this incredible system, which has never been damaged by a wind event.  A.C.I. has installed the VADA system on large commercial and industrial projects across the U.S.
