How much soffit venting 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.
Can I drilling holes in soffit for ventilation?
It is recommended that the holes be drilled at a rate that will allow sufficient airflow to match the flow of passive vents in the attic. For example, when using a 1 1/4-inch paddle drill bit, it is recommended that up to 10 holes be drilled into the soffit area for each linear foot of soffit area.
Should all soffits be vented?
So, does my roof need soffit vents? 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. There is no question that a standard attic space should be vented.
Should I use all vented soffit?
There are a few reasons why a properly ventilated attic using vented soffit is beneficial for homeowners. A properly balanced attic airflow system using vented soffit can help save on your monthly utility bills as it ensures your house consumes less energy, particularly when it comes to cooling.
Can you have too many soffit vents?
You can’t have too much soffit venting, but it’s worth noting the minimum requirements. Usually, 4-in. by 16-in. soffit vents are rated for 26 sq.

What is the 1 150 rule?
Key notes/changes: The minimum amount of attic ventilation remains 1/150 (1 square foot of Net Free Area for every 150 square feet of attic floor space. Attic floor is defined as length x width FLOOR of the attic).
Should all soffit be vented?
While soffit comes in wood and aluminum, they are most commonly made of vinyl for durability. Soffit can be non-vented or vented to allow for maximum roof ventilation. 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.
How big should soffit vent holes be?
Each hole should be cut slightly smaller than the corresponding vent, whether you’re using a circular or a rectangular vent. So when you make your cuts, go 1/2- to 3/4-inch inside the lines.
Can you have too much soffit venting?
Do soffit vents work without ridge vents?
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.
Can you have too much soffit ventilation?
The two main dangers associated with too much ventilation involve roof damage and increased utility bills. If you have too much air circulating, your roof will collect moisture causing damages that will weaken spots and then cause leaking.
What happens if you dont vent soffit?
The Bottom Line On Attic Venting Without Soffits
If your attic has inadequate ventilation, it can act like a “heat trap” and lead to premature shingle aging, warp wood sheathing, lead to mold issues, and increase your HVAC costs.
Do I need gable vents if I have soffit vents?
Gable and ridge vents both work ideally with soffit vents. Soffit vents are far below the level of gable vents or ridge vents. Therefore, the cool-air intake for attic ventilation needs to be significantly lower than the exhaust for your ventilation system in order to work effectively.
Can you have too many roof vents?
It’s possible to have too much exhaust ventilation, but you cannot have too much intake ventilation. If there is more intake ventilation than the attic’s square footage requires, it’s not problematic because any excess intake converts to “exhaust” on the leeward side of the house.
Should I use vented or solid soffit?
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. Vented soffit panels are good with a wider eave and a smaller amount of attic space because they have smaller vents between solid panels.
Can you have too much attic venting?
When should you not use a ridge vent?
During heavy rains, deep snow or high winds along with rain can enter through the vent and stain the ceiling below. Most manufacturers state that a ridge vent should not be installed on a roof with a pitch (slope) of 3-1/2 in 12 or less.
Is it better to vent through roof or soffit?
Whether it’s new construction or a remodel, a bathroom vent should always vent through the roof instead of an eave, overhang, or soffit. The point of a bathroom exhaust vent, or any vent really, is to remove hot, moist air from the house.
Should soffit vents be continuous?
Continuous ventilation systems with ridge and soffit vents keep attics dry. Moisture in the attic can cause mold to grow and the wood can rot, so air circulation is very important.
Can I have too much soffit venting?
How do you tell if your attic is properly ventilated?
How to determine whether you need better attic ventilation
- Look at your eaves and roof.
- Touch your ceiling on a warm, sunny day.
- Thick ridges of ice on your eaves in winter are a sign of poor attic ventilation.
- Warm air that escapes living space also carries moisture that will condense on rafters or roof sheathing.
