You’re dealing with “roof edge venting” or “drip edge venting”, and the gap is implied as a requirement. If you like, call it a “roof edge vent gap”. Thanks. I’ve asked the local building inspector to tell me if such a gap is up to code (the house was built in the 1940s).
Which type of roof vent is used for air intake?
There are two types of intake vents: soffit vents and rooftop intake vents. Most homes have soffit vents if they are constructed with roof overhangs or eaves. Because the soffit is typically located at the lowest point of the roof, it’s in the perfect spot for fresh air to enter the attic.
What is a soffit intake vent?
The Under Eave Soffit Vent is an air intake roof vent. To clarify, Soffit Vents are roof vents installed underneath the eaves of a roof that extend past the warm wall line. When properly combined with other roof ventilation devices, soffit vents allow fresh air to enter into an attic to create proper airflow.
What is a roof edge vent?
Air Vent, the industry leader in residential attic ventilation has a shingle-over, edge-of-roof installed intake vent – The Edge™Vent. It not only provides continuous intake airflow at the roof’s edge but it significantly simplifies intake vent installation by keeping the roofing contractor on the roof.
What is a drip edge vent?
Air Vent’s Pro Flow™ Vented Drip Edge combines venting with a drip edge and is used to provide intake ventilation on homes with little or no soffit area. The vent provides 9 square inches of net free area per linear foot.

WHAT IS A intake vent?
What Are Intake Vents? Air intake vents are used to allow outside air to enter into attics and ventilation spaces. Intake vents should be located along a roof assembly’s lowest eaves at or near soffits. Intake vents are best used with exhaust vents that are located at or near a roof assembly’s peak.
Are gable vents intake or exhaust?
The gable vents turn into intake vents and bring in warmer air to the attic space. Some attic fans or whole-house fans are too powerful for the attic. If the negative pressure they create by exhausting attic air is strong enough, they can draw conditioned air from your living space into your attic, and then outside.
What are eaves vents?
Eave vents are a vital part of many roofing systems. They help air flow beneath your roofing sheets or tiles to combat the build-up of moisture. You will often combine an eave vent with ridge ventilation to ensure your roof space is fully vented.
How do you install a roof intake vent?
Quote from Youtube video: When installing in cold weather. Leave a 1/8 inch gap between consecutive intake vent sections to allow for thermal expansion. Run the intake vent the full length of the eave.
What are eyebrow vents?
Static vents, also referred to as roof line or eyebrow vents, are metal cylinders with a flashing collar and a hood, which keep the rain out. This type of intake vent is installed by cutting rows of holes along the face of the roof and nailing the vents’ flashing collars to the roof sheathing.
How many dormer vents do I need?
A general guideline is homeowners need one square foot of roof vent for every 300 square feet of ceiling space, if your home has a roof with a vapor barrier, or 1:300. If not, you should have one square foot of roof vent for every 150 square feet, or 1:150.
What is a turbine vent?
Turbine vents (also known as whirly birds) work by using a drawing effect through convection (heat rising) to move the air in your attic around even when there is no wind. As long as this type of vent is installed properly, the air in your attic is moved around 10-12 times per hour.
What is a turtle vent on a roof?
Turtle vents are non-mechanical curved vents (yep, like a turtle shell) that allow hot air to escape the attic space. If not used with soffit vents, they typically only release air where they are installed. Gable vents are rectangles vents generally found on the front or sides of a house, below the roof ridge.
How far apart should roof 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.
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.
Where do roof vents go?
Mark the roof venting locations from the attic, where you can see the rafters and avoid placing roofing vents over them. Place all the roof vents on the same side of the roof. If your roof peak runs parallel to the street, put them on the backside, where they’ll be less prominent.
What is ridge vent in roofing?
A ridge vent is an air exhaust vent installed on the peak of a roof. When installing this vent, an air slot is first cut in the roof deck at the roof’s peak. This air slot is then covered by the ridge vent itself.
