Is attic fan necessary with ridge vents?
Combining an attic power vent fan with a ridge vent is usually not recommended because: It could reverse the natural flow of hot air out the ridge vent. If air is drawn in through the ridge vent while it’s raining, it might pull rainwater in with it, which could lead to leaking or mold in the attic.
Are ridge vents better than attic fans?
If you had to choose just one—and your attic has a great need for ventilation—an attic fan is your best bet. Attic fans in the $300 to $400 range can move upwards of 5,000 CFM. For lower capacity ventilation at a steep cost savings, a ridge vent might be your best choice.
Does ridge vents really work?
The truth is, most experts agree that though other roof vents allow some ventilation (which is better than none), ridge vents are the most efficient and cost-effective roof ventilation system around. Our recommendation is yes. Especially if you are installing a new roof, you want to extend its life as long as possible.
Is ridge vent enough for whole house fan?
If you have a home with a ridge vent… the type of vent that runs along the peak of the roof, you don’t even have to measure. A 40ft long ridge vent is equivalent to 20 sq. feet of gable vent… more than enough venting for even the largest whole house fans.

When you have a new home built, or you’re replacing a roof, then installing a ridge vent helps to balance out the transfer of hot and cold air.
Will a ridge vent cool my house?

The unintended consequence of your recently installed roof vents is that your house got colder. In the winter months, warm attic air is vented to the outside through the ridge vents and is replaced by colder outside air sucked in through the soffit vents.

How many vents do I need for a whole house fan?
Venting Requirements A rule of thumb is that you should have one square foot of “net free venting area” for every 750 CFM of airflow. So at 3000 CFM, you’ll want four square feet of venting. Most modern homes easily accommodate this rule, but it is important to check to ensure optimum system efficiency.
Is a ridge vent enough ventilation?
A ridge vent along with other vents that draw in colder air is enough ventilation. However, a ridge vent alone without some intake vents wouldn’t do as much. We highly recommend installing soffit or gable vents along with a ridge vent or some other form of air intake.
Are ridge vents better than whirlybirds?
While ridge vents win for their subtle appearance and functionality, turbine vents may be better in especially hot or humid climates where more dynamic airflow is necessary. If you are not sure which to use, consult a roof professional who can examine the needs of your home and draw up a venting plan for you.
Why is my attic so hot in winter?
Many attics contain ductwork that supplies cool air to upstairs rooms during the summer and heated air during the winter. If the joints in your ductwork are not properly sealed, your forced air system can suck attic air into the ducts –air that’s either really hot in the summer or really cold in the winter.
Is a ridge vent really needed?

Should I install a ridge vent?
– Hard to install – Doesn’t work with warmer climates – Can be more expensive – Not guaranteed ventilation – Can cause leaks from rain
Are ridge vents the way to go for attic ventilation?
The majority of roofing experts agree that ridge vents are the most effective and cost-effective roof vents available. Without baffles (blinders that prevent outside air from crossing over the vent), a ridge vent may create almost no ventilation at all. Gable vents may circulate air through only a small percentage of your attic.
Should I install ridge vents?
Ridge Vents Don’t Allow For Consistent Ventilation. When you’re going to the trouble of installing a vent,you want the airflow to be consistent.
