The Problem

The Solution

PCM/Wind Vented Roof System

A Whole New Way to Think About Roofing

The ERC Wind Vented roof system literally uses the power of the wind’s negative uplift effect, to hold a flat roof system securely in place against the very force that is most destructive to a roof… the wind.

If you’ve ever wondered how a plane manages to take flight, let alone stay in the air – it is due to the “Bernoulli Principal”. When air hits the rounded edge and curved face of a plane wing, the air flow ABOVE the wing travels faster than the air flow BELOW the wing. This creates a difference in pressure, which has a lifting effect.

It is for this same reason that an increase in wind speed ABOVE a roof, with practically NO wind speed below the roof creates an UPLIFT effect… the most damaging problem for a roof.

The ERC wind vented roof system uses proprietary one-way-vortex valves installed at the perimeter of a roof to provide pressure relief. This pressure relief then creates a suction or vacuum effect that literally holds the roof system in place the harder the wind blows!



Are you fighting having to tie up much needed capital to replace your roof, or get a high quality roof on your next project?

The PCM/Wind Vent Roof solution is the only roof system that can dry out a wet existing roof below! This means that in many cases we can install over existing roofs without a complete roof tearoff!

And with 30 Year & 150mph Wind Warranties Backed by Fortis… what’s not to love?

Infinite-R™  Phase Change Mats

Energy Savings that Pay For Your Roof

  • Reduce Energy Costs, Increase Comfort
  • Thin, Lightweight & Easy to Install
  • Store “Off-Peak” for daytime use!
  • Fast Payback: Heating & Cooling Savings

Phase Change Materials work like ice inside a cooler. As they melt, they absorb heat without changing temperature until completely melted. As they freeze, they release that heat back again.

Infinite-R™ can be located within your roofing system to shield your building from hot roof temperatures in summer, while stabilizing interior heating temperatures in winter and stopping drastic temperature drops overnight during “un-occupied” cycles.

Infinite R PCM

The Highest Quality Roof

Less Labor, Less Landfill & Less Energy Use!

The PCM/Wind Vented Roof solution can be used in both New Construction & Roof Replacement programs. When used in existing roofs that are saturated, contain asbestos or require a complete tear-off, the savings can be significant!

ERC’s Wind Vented Roof Systems use an air barriers and air sealed substrate design. This means that wind generated vacuum pressures pull air and moisture from under the roof membrane, up through and out of strategically placed one way vortex valves. A suction is created, pulling the roof membrane tight against the substrate.
