Lower Roof Intake Vent

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.

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.
