The WeatherPRO® Roof Vent Baffle System Advantage

The standard roof vent design used in our Duraflo® Square Top Roof Vents has been around for over 40 years and not much has changed in that time… until now.


The idea of the standard roof vent is simple: airflow streams out of the attic through the bottom of the vent, getting rid of stale, old air from your home; however, sometimes these simple vents would also allow snow to fall straight into the attic. 

In places like northern Ontario, where snow is a commodity, these vents don’t provide much in terms of protection from the weather. 

So what if we were to make it much more difficult for rain or snow to make it inside your home? 

This was the thought process behind the design of our WeatherPRO® Baffle System.

In this system, air exits out of the top of your vent, instead of from underneath it. A set of inner and outer walls provide high airflow while deflecting water and snow. The design also includes drainage openings to send water out the vent and down your rooftop. 

This type of baffle system was the first of its kind when it initially launched. Now we’re using it in several of our products, such as the WeatherPRO® Slantback, the WeatherPRO® PRO50 and the WeatherPRO® PROTurbo

Thanks to the feedback from contractors and customers, the initial design of this patent has since changed from when the product first came out. Our vents are now able to provide excellent defence against weather infiltration.
