Discover SNOWVENTCO Snow Vents.
The ONLY Type B 50 sq. in. flow static box vent that actually keeps out over 99% of snow in blizzard conditions.
The SNOWVENTCO Snow Vent was created by a roofer to tackle tough Canadian winters. Approved by the Canadian Standards Association, SNOWVENTCO Snow Vents have been tested to stop over 99% of snow and effectively redirect rain during severe storms.

How do SNOWVENTCO Snow Vents protect your attic from moisture?
Constructed with a heavy-duty ¼ inch thick polypropylene shell and 304 grade stainless steel filter, the SNOWVENTCO Snow Vent provides a no-clog, 99.99% impenetrable barrier to snow, rain, and other elements.
UNIQUE MICROPORE STAINLESS STEEL FILTER
The next generation in ventilation begins with SNOWVENTCO'S STAINLESS STEEL SMART FILTER. Thousands of 120-micron holes keep out driven snow particles and other unwanted elements.
ENGINEERED NOT TO CLOG
Snow and dirt won't block the vent, thanks to the porcelain-like smoothness of the steel screen and the outflow of warm air from the attic, which continuously cleans the filter.
EXCEEDS CSA REQUIREMENTS
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.
Why do roofers prefer SNOWVENTCO Snow Vents?
Heavy-Duty Construction
Extra-thick polypropylene construction and the steel filter ensure the vent can handle a lot of punishment. The hail resistant SNOWVENTCO
Snow Vent withstands over 180kg/400lb of standing weight.
Oversized Flange
A wider flange makes installation a snap and helps improve the overall seal. This simple improvement has been demanded by roofers for years.
Arched Design
An arched collar and cap help snow slide off the vent, avoiding build-up behind the vent. The arched deflector on our intake vent diverts rain.

Frequently Asked Questions
Roof vents are necessary in order to improve the ventilation in your attic. Adequate ventilation helps to remove excess heat and moisture from your attic, which can prolong the life of your roof and prevent damage to your attic and the rest of your home. Additionally, proper ventilation can help to prevent the growth of mold and mildew, which can be a health hazard.
There is no one "best" roof ventilation system as the appropriate system will depend on the specific needs of your home and roof. Roof vents are generally divided into active or passive systems with each system having its pros and cons.
The number of roof vents you need will depend on the size and layout of your attic. A general rule of thumb is to have 1 square foot (144 square inches) of vent area for every 150 square feet of attic space. For example, if your attic is 900 square feet, you would need 864 square inches (6 square feet X 144) of vent area. Additionally, it's important to make sure that your vents are properly placed and balanced, with an equal amount of intake and exhaust vents. This will ensure that air is flowing effectively through your attic and not creating pressure that could cause leaks or damage to the roof. Try our roof vent calculator to find the right amount of vents for your roof.
Installing roof vents can be a complex task that requires a certain level of skill and experience. It is recommended that you hire a professional roofing contractor to install your vents, as they will have the knowledge and tools necessary to do the job safely and correctly. However, if you're determined to install them yourself, take a look at our installation video for a step by step demonstration.
No, determined vermin will have a difficult time chewing through the heavy duty plastic outer shell which is much thicker than typical roof vents. If they are able to chew through the plastic they will not be able to get through the stainless steel filter. This will restrict attic access through the vent openings.
Roof vents can breathe under snow, but it depends on the amount of snow and the type of vent. SNOWVENTCO vents have been tested to allow for airflow even under heavy snowfall conditions. See the link below for video proof.
Yes, the low profile and aerodynamic design of SNOWVENTCO vents combined with heavy duty polymer outer shell mean the SNOWVENTCO vents are very resistant to high winds. Our vents have undergone testing showing that they prevent over 99% of rain, snow, and other particle penetration of attic in CAT 3 hurricane wind conditions. They are also durable enough to stay intact when faced with 120 mph winds.
