How do you vent a roof with no overhang?
The most common way to add ventilation to an attic is by installing air intakes in the soffits and putting an outlet at the gable of the house. This creates a natural air flow by drawing in the air from outside, pushing it up and out through the vent at the top of the house. This is called passive ventilation.
What can I use if I don’t have soffit vents?

Will a ridge vent work without soffit vents?
Ridge vents can work without soffit vents, however, this won’t be very energy efficient. Without soffit vents, the ridge vents will draw air from some other inlet on the roof like a gable, but this will limit the extent of air circulation in the attic.
Are soffit vents necessary?
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.
What happens if a roof is not vented?
Unventilated or poorly ventilated attics don’t have an escape route for the heat that builds up. This buildup of heat can damage your shingles from the inside out. An evenly vented roof will allow the hot air to escape keeping your roof and attic cooler.
How do you vent a roof without eaves?

How do you make a vented soffit?
How to Install Soffit Vents Step 1: Make Two Parallel Lines. Step 2: Cut Parallel Lines. Step 3: Connect the Two Cuts. Step 4: Raise the Vent up to the Soffit. Step 5: Attach the Vent to the Soffit. Step 6: Remove Any Insulation From the New Vent. Step 7: Install the Ventilation Baffle.
What is a turbine roof vent?
A turbine vent is a passive ventilation device. A turbine vents spins with the slightest breeze. As soon as it starts to spin, it vacuums air out of your attic. The faster it spins, the more air it exhausts.
How do you vent a hot attic?

Do I need soffit vents if I have roof 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.
Do you need roof vents if you have a ridge vent?
Does my roof need a ridge vent? Yes, If you live in a hot or humid climate a roof ridge vent can lower your cooling bills and lower you attic temperature.

Should I use vented or solid soffit?
Vented Soffit Panels Increase Air Circulation Due to the small perforations, vented soffit panels increase the air circulation of the attic area. Solid soffit panels, on the contrary, effectively seal off the attic space from fresh air, causing the air inside to become trapped and grow stale.
Can you have too much attic ventilation?
Dangers of Too Much Ventilation If you have too much air circulating, your roof will collect moisture causing damages that will weaken spots and then cause leaking. During the warmer months, your air conditioner is going to kick into overdrive to keep up with the warm air that comes in from the outside.
Where do you put roof vents?
