What spacing should soffit vents be?
How Far Apart Should Soffit Vents Be? The ideal space between soffit vents will depend on your roof’s total square footage (or attic) and the number of soffit vents used to ventilate it. It’s recommended that all soffit vents be spaced at equal distances from one another on the sides of your roof under the eaves.
How many soffit vents do I need?
Most professionals recommend one square foot of ventilation for every 150 square feet of attic area. This will help you determine how many soffit vents you need. For example, a 15′ x 40′ attic would have a total area of 600 square feet; divided by 150 equals 4 square feet of total ventilated space needed.
Will soffit vents work without a ridge vent?
A functioning ridge vent will allow the hot air to escape through the roof. The air comes in through the soffit vent, and exits through the ridge vent. It’s as simple as that. A ridge vent without soffit vents won’t work as intended, and vice versa.
How do you improve soffit ventilation?

How big should soffit vent holes be?

Should soffits be vented?
A roof may need soffit vents if there is no other ventilation allowing for adequate air movement. However, if the attic space is properly sealed and insulated, there is no need for this type of ventilation. Soffit vents are an easy, aesthetically pleasing way to vent the attic space.
Do I need baffles in every rafter?
This is so that cooler air outside can replace the hotter air in attics. Attic venting baffles channel the air from outside, continuing the circulation. This is what keeps your home cooler. So, while rafter air channels are not required between every rafter, they are necessary for each air intake piece.
Where should attic baffles be installed?
Baffles are installed in the attic (or should be), wherever there is an intake vent (soffit vent). Baffles ensure proper airflow into your attic space. Baffles prevent vents from getting clogged by insulation and ensure a clear channel for outside air to move into the attic through soffit vents.
What are soffit baffles?
Baffles are chutes that, when installed properly, can provide a channel for air to flow from your exterior soffit vents up into your attic space. That airflow is intended to churn the stale air in your attic which helps to remove moisture and control the temperature of your attic.
Do soffit vents need screens?
The holes in the continuous soffit venting should be small enough to prevent insects from entering. Aluminum soffits, with continuous venting, were intended to be installed without screening.
How do I know if my soffit vents are working?

Non-vented or continuous soffit works best when your roof has narrow eaves or if you need to ventilate a large amount of attic space.
Should soffit vents be covered with insulation?
In the summer, natural air flow in a well-vented attic moves super-heated air out of the attic, protecting roof shingles and removing moisture. The insulation will resist heat transfer into the house. NEVER COVER ATTIC SOFFIT VENTS WITH INSULATION — use rafter vents and soffit vents to maintain airflow.
What can I use if I don’t have a ridge vent?
Most of the estimators mention the option of a ridge vent installed at the top of the roof, some mention it in passing and don’t really push it too hard one way or the other, and others, while not exactly insisting it be installed, say that without the installation of a ridge vent, the attic would receive inadequate Jun 26, 2015.
