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.
Baffles keep the insulation from blocking the vents in the soffit. If you don’t have vents there, baffles would be useless. In your situation, it would be easiest to install vents in the peak walls at the ends of the building. They work just as well as vents in the soffit.
Beside this, Are soffit baffles required?
Installing baffles from a soffit vent and up the rafter bay allows you to insulate every available inch of attic floor space. Without baffles, you must keep vents clear of insulation, which means the space around the vent typically receives no blanket of protection.
Likewise, Do you need baffles between every rafter?
However, in a “normal” (if there is such a thing) attic, you don’t “have” to have baffles or vents in every rafter bay. You just need to meet the minimum free area for that size attic and MAKE SURE that there is at least as much intake, if not more, as there is exhaust.
Also, When should you use vented soffit?
The primary reason for installing vented soffit is to ensure that your home has proper air circulation in the attic. While it may seem contrary, having proper ventilation actually prevents issues related to moisture build-up and increased energy costs.
Should I use all vented soffit?
Do I need the entire area to be ventilated? In short the answer is no for most houses as shown in this picture; you see that open space – well that allows air to flow from one bay to another. Now if those rafter tails are blocked off or you used I-Joists, then the answer is that yes you need soffit venting in each bay.

Are rafter vents required?
To completely cover your attic floor with insulation out to the eaves you need to install rafter vents (also called insulation baffles). … Rafter vents ensure the soffit vents are clear and there is a channel for outside air to move into the attic at the soffits and out through the gable or ridge vent.
Can you have too much soffit venting?
Theoretically you can have too much soffit venting if the system is out of balance dramatically but most homes are out of balance in the wrong direction (i.e. too much exhaust and not enough intake).
What happens if your attic is not vented?
But in homes without appropriate insulation and ventilation in the attic, heat migrates. … Meanwhile, because hot air is full of moisture, all that water hanging out in your attic is causing condensation to build up. Excess heat and condensation can cause major damage to your roof and roofing materials.
Are baffles necessary?
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.
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.
Are attic vents required?
The U.S. Federal Housing authority recommends a minimum of at least 1 square foot of attic ventilation (evenly split between intake and exhaust) for every 300 square feet of attic floor space.
How far apart should rafter vents be?
The general rule of thumb on the amount of total attic vent space needed is to have at least one square foot of vent space for every 150 square feet of attic area.
Do I need baffles in every rafter?
However, in a “normal” (if there is such a thing) attic, you don’t “have” to have baffles or vents in every rafter bay. You just need to meet the minimum free area for that size attic and MAKE SURE that there is at least as much intake, if not more, as there is exhaust.
What can I use if I don’t have soffit vents?
One great alternative to a soffit ventilation system is to install an intake vent right at the lower edge of the roof. They call this a venting drip edge. The venting drip edge seems to be the easiest and most common way to go.
Do I need rafter vents in every rafter?

Do ridge vents work without soffit vents?
Rose, a research architect at the Building Research Council at the University of Illinois, replies: A ridge vent without a soffit vent doesn’t work, and here’s why. By virtue of their design and location on the roof, ridge vents are predominantly exhaust devices.
Does every rafter need a baffle?
You will need a baffle for each space between the rafters. Fit each one snuggly in the bay, with the bottom starting where the ceiling joist meets the roof rafter.
