How do Smart 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.


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.


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.


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.

Chislett Roofing has been in business for over 40 years and we shingle over 4,000 homes each year in Ontario. In the winter, constantly blowing snow through roof vents can be a real problem in our area. We have used SNOWVENTCO roof vents for years and their snowproof stainless steel filter is a great solution. These vents are a little more expensive, but leaking vents silently destroy attic insulation. Today over 90% of our installs use only SNOWVENTCO.

About time someone made a vent that does what it's meant to all year round!!! Good vent - will use on all my own roofing jobs.

The roof vents in today's market are very low quality, have a short life span and a high tendency to fail. This leaves homeowners with multiple problems including bugs/wasps, mould, overheated roofs and, most of all, water damage caused from leaking and major snow intake. When I first saw the new SNOWVENTCO Roofers' Vent I immediately liked its sleek look as well as its craftsmanship and durability. I would recommend this vent to anyone without hesitation. It's by far the most state of the art roof vent available today.

Brighton, Ontario

I have not had a good product available to stop the snow from being blown into an attic during a windy snow storm, UNTIL NOW! The SNOWVENTCO Roof Vent will be the ONLY vent I recommend for use on any roof in any location that ever gets snow! A journeyman roofer from Germany taught me the roofing trade, but was always looking for a good vent that would keep snow out. Now we have a good vent, one that really works, available for our customers.

Frequently Asked Questions

Why do I need roof vents?
arrow down to open frequently asked question

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.

What is the best roof ventilation system?
arrow down to open frequently asked question

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.

How many roof vents do I need?
arrow down to open frequently asked question

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.

How Do I Install SNOWVENTCO vents?
arrow down to open frequently asked question

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.

Can Raccoons, squirrels, or other rodents chew through the vent and gain entrance into my attic?
arrow down to open frequently asked question

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.

Can roof vents breathe under snow?
arrow down to open frequently asked question

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.

Will SNOWVENTCO vents perform well under high wind conditions?
arrow down to open frequently asked question

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.
