What is a ridge vent?
Whats a ridge vent? A ridge vent is a humidity and heat transfer vent installed on residential roofs , especially in hot and humid climates. They help circulate the air by giving hot air a place to go. Ridge vents run the entire length of a roof and generally include soffit vents that let cooler air in. Venting an attic properly is all about circulation. If you want to push out hot air then you have to take in some that’s cooler. Taking in air requires other vents because ridge vents are only for expelling the hot air. So for ridge vents to work their best they should be installed with other vents that act as an intake. These are best located inside the soffits.
Which is better, a ridge vent or a turbine vent?
Ridge vents are much better than turbines and other forms of attic venting provided they have enough continuous fresh air intake through other vents. The best way to intake fresh air is through the soffits. Soffit vents draw fresh, cool air in which is then expelled through the ridge.
Why won't my attic vent work?
One without the other won’t work as well because hot air has to be pushed out of the vent by incoming colder air. It’s all about the air pressure. Without an intake there just isn’t enough pressure to get the hot air out.

What is the vent on the top of the roof called?
They run along the top of the roof which is commonly called a ridge . Hot air rises, so putting a vent along the highest point of the roof makes the most sense.

Does Hammer1 use gable vents?
Hammer1 has given up on gable vents entirely. “The reason we changed from using gable vents is that they don’t work,” Hammer writes. “Hot air in the attic forms pressure and won’t allow outside air in.

Is ridge venting or soffit venting good?

Do ridge vents work in the attic?
If they work at all, it’s usually just in the area close to the gable vents, not the entire attic.

Ridge Vent vs. Attic Fan: Major Differences
Roof ridge vents and attic fans both promote airflow in attics. Unlike attic fans, ridge vents are passive, not mechanical, ventilation devices. Also, ridge vents move air both in and out of an attic; attic fans mostly move air outward, from the attic's interior to the outdoors.
Installation
A ridge vent is easier to install when the roof shingles are first installed, but ridge vents can be installed retroactively, too. Roof installers cut through the shingles and the wood roof deck but stop short of the roof rafters, creating a 6-inch continuous slot.
Appearance
Ridge vents blend in well with the roofline. Even with added shingles, ridge vents are barely more than 1 inch high. Since they follow the roof ridge, they are not usually visible.
Cost to Operate
Being passive venting devices, ridge vents are openings in your roof; they do not move. No motors are needed for operation. While ridge vents do occasionally need to be cleared of debris, there is no cost to operate them and little cost to maintain them.
Which Should You Buy?
Attic ventilation of some type is required by most building codes. 1 Ridge vents and attic fans can work in conjunction with each other. In this scenario, the ridge vent passively handles ventilation and cooling duties until it reaches its full capacity. Then, the attic fan takes over.
