Extra-thick polypropylene construction and the steel filter ensure the vent can handle a lot of punishment. The hail resistant SNOWVENTCO Roofers’ Vent withstands over 180kg/400lb of standing weight.

A wider flange makes installation a snap and helps improve the overall seal. This simple improvement has been demanded by roofers for years. 

An arched collar and cap help snow slide off the vent, avoiding build-up behind the vent.

Insects can't penetrate the SMART FILTER, while pesky raccoons and squirrels won't like gnawing through steel.

The next generation in attic ventilation begins with SNOWVENTCO'S SMART FILTER. Thousands of 120-micron holes keep out rain, snow and other unwanted elements.

These vents have received a stamp of approval from CSA. The SMART FILTER provides over 80 sq inches of open airspace for a 50 sq inch vent. This 60% over engineering of net free area (NFA) ensures strong attic airflow while the filter completely blocks the elements and exceeds CSAs requirements.
