Best Roof Ventilation Methods
Talking about ventilation, there are two main kinds of ventilation: exhaust and intake ventilation. Both of which need to be installed in your house to keep the air circulation ‘balanced’. Not only the system lets the stinky, dirty air out, but it should also grab some outdoor fresh air to be taken to your house.
Therefore, when we talk about the best roof ventilation methods, we cannot just talk about roofing exhaust vents. Let’s discuss the roofing intake vents as well.
1. Exhaust vents
One of the renowned exhaust vents is ridge vents. This kind of exhaust is typically placed on the roof peak and elongates along the roofline. It probably becomes the most common vent ever installed due to this roof vent placement itself.
Located on the house’s highest altitude, it can let the hottest air escapes the attic space. Another upside of it is its functional area. Despite being only on the roofline, it has effectively functioned to take out evaporating the house’s large amounts of humidly hot air.
Other kinds of exhaust vents will involve:
- Off ridge vents
- Box vents
- Roof turbines
- Solar-powered vents
- Electricity-powered vents.
2. Intake Vents
Some of you may have heard of soffit vents. By far, soffit vents are the commonly used intake venting. Along with ridge vents, it becomes the most-effective vents combo loved by many. Not only is it effective, but it also comes with a lower price.
While typically exhaust vents are installed upon the roof’s peak, intake vents like soffit vents are placed along the roof eaves. Soffit vents come in two types: individual and continuous ones. Continuous soffits are functioning similar to ridge vents but placed along with the vents and enabling massive air to pass through.
Individual soffits, which are made of aluminum – are similar to box vents. Hence, it has spacing from one soffit to another, usually 5-6 feet apart.
Other types of intake vents will include:
- Drip edge vents
- Gable vents
- Over-fascia vents.
Best Roof Vents for Houses
Your exhaust and intake vents preferences may not be the same as another house owner. You may prefer a simple venting system, such as using a ridge vent and continuous soffit vent for your house. After all, its price is lower. But another person may say no to such a simple ventilation system.

Well, it is best to choose your venting system according to your budgeting and needs. You may prefer to have a roof turbine, but that venting system doesn’t sound appropriate for a simple suburban house. You may also prefer gable vents, but your roof isn’t even a gable one.
Remember, you should also consider its budget matter as well. If you want to pick a combo of the most inexpensive, then having a soffit vent and ridge vent is a great choice among all types of roof vents.
How Many Roof Vents Do I Need?
After knowing the best roof ventilation methods, let’s get to know how many roof vents you will need for your house.
As a general rule, your roof needs ventilation per 300 square feet, given that your roof has a vapor barrier. If your roof does not have it, then the ratio increases to one roof vent per 150 square feet ceiling area.
Let’s say that your roof has a width of 1,200 square feet and is ‘equipped’ with a vapor barrier. Then you’ll need 4 roof vents. Then, you can pick any of the best roof ventilation methods mentioned above.
