The Solution to Common Roof Venting Issues

snow covering rooftop and roof vents

When it comes to extreme weather conditions, the WeatherPRO® PROTurbo is the solution.

Here are two scenarios:

Scenario A: You have a traditional turbine vent on a metal base.


In this scenario, the turbine vent moves air by rotating. The turbine functions well, as long as it does not stop moving due to snow / ice accumulation, or seized bearings; then it becomes susceptible to weather infiltration. Airflow for traditional turbine vents works well only when moving.

To install the metal base, the installer should use a level to ensure that the vent stands upright, which changes depending on the roof pitch. There is also some assembly and adjusting of the of the components meaning that installation can take a lot longer.

It is this first scenario that had two Duraflo® design engineers brainstorming solutions to solve the problems customers were facing with traditional turbine vents. 

And that is how they came up with Scenario B: the WeatherPRO® PROTurbo and Easy Level Base.  


Scenario B: You have a WeatherPRO® PROTurbo vent on our polypropylene Easy Level Base. 

In Scenario B, the vent has no rotating parts. Instead, it uses our Airfoil baffle system, the same that is in our WeatherPRO® PRO50. When the wind blows across the vent, it hits the large vertical band in the middle and creates negative pressure above and below the grills to help draw air out from the attic space. Thanks to the internal baffle system, rain, and snow melt, drain out the bottom of the vent through the weeping holes.

Here, we are utilizing our patent-pending plastic Easy Level Base. It is an improvement over the typical metal base, which installers still have the option of using. To use the Easy Level Base, the installer sets the base on the roof, and uses two tabs on the front of the base to click it into place; no level needed.

The Easy Level Base design was adapted from our WeatherPRO® PROVentilator, which went through rigorous testing and changes based on customer feedback. 

The patent is still pending on this base, but we’re looking forward to bringing it to our customers as a part of our constantly evolving and improving product line.
