Vortex Valves System to Protect Your Roof

Get years of effective protection from the Vortex Valves System from Epic Roofing Solutions in Raleigh, North Carolina. The system contains no moving parts, reduces installation time, and minimizes the need for traditional fastening methods. The unique shape allows it to perform effectively with any wind direction.

Based on Scientific Principles

The Vortex Valves System is different from existing roof vent devices because it uses the Bernoulli and Venturia principles to capture the dynamic flow of air across the roof's surface to generate low pressure. The vent works with the effects of the wind instead of against it. It is manufactured from a single ply material that is strong enough to resist excessive wind speeds, yet lightweight enough for ease of handling and installation.

Problem and Solution Infographic

Using Wind Power

The Vortex Valves System uses the power of the wind to hold the roof securely in place. Based on a recognized principle of physics, the vent creates a vacuum that becomes stronger as the speed of the wind increases. The vacuum pulls the air from under the membrane—drawing it down to the deck and holding the membrane firmly in place. Destructive uplift pressures are counteracted by a greater vacuum force under the membrane created by the vent. The harder the wind blows, the better it works.

Great for Low-Sloped Roofs

By accelerating the wind through this unique design, the vent lowers the pressure under the membrane, reducing the need for conventional attachment methods. This technology is ideal for low sloped roofs in environments with high winds, such as in south Florida, and on buildings where fully adhering a membrane is too costly an option.

How It Works

The contractor creates a seal to prevent positive pressure from entering through the roof system by using Vortex Valves, which are strategically placed in the vortex areas to take advantage of the wind-generated vacuum pressures and pull air and moisture from under the roof membrane. The suction causes the roof assembly to be vacuum packed to the roof deck. The system causes a continual drying of the roof substrate. Wind-generated low pressure transferred under the roof membrane causes water in the roof assembly to vaporize. Water in this gaseous state can then travel under the roof membrane and be drawn out through the valves when the wind blows. Should roof damage occur in the future, causing leaks, the wet roof insulation substrate will dry itself out once the source of the leak has been repaired.
