The Five Main Types Of Roof Vents

Roof vents are designed to ventilate your home in the summer, removing hot and humid air out of your attic while allowing cooler air to seep inside. There are several different types of roof vents, all of which operate in different manners to perform the same function. Understanding the differences between these five main types of roof vents can help you choose the one that is the best fit for your home.

1. Box Vents

Box vents are small low profile vents that are mounted on your roof. They resemble very small boxes, hence the name, and have no moving parts in them. They make use of passive air flow to move the hot air out of your attic. This means that box vents are usually installed in groups, as the amount of air flow that each vent generates is not enough to properly ventilate an entire attic.

2. Wind Turbines

Wind turbines look like chef hats and are mounted on the ridge of your roof. They have a moving cylinder on the top that rotates due to the wind, allowing more air to flow into and out of your attic as long as the wind is blowing. It's important to note that these will need more maintenance than box vents, as they can begin to squeak when they rotate over time.

3. Power Vents

Power vents are roof vents that have a motor in them to forcibly circulate air throughout your attic. They come with adjustable thermostats which allow you to set the temperature that you want to maintain your attic at. However, power vents represent a long run cost as they will increase your energy bills over time, though some solar powered models are available.

4. Soffit Vents

Soffit vents, also known as eave vents, are installed in the soffits (the underhanging part beneath the gutters). Like box vents, they are passive, and simply offer another avenue for air to flow into your attic. Soffit vents are not effective enough to properly ventilate an entire attic on their own, and as such are usually used in conjunction with another type of roof vent.

5. Ridge Vents

Ridge vents operate on the same principle as box vents, and are located along the entire length of your roof's ridge. However, ridge vents are form fitted around your roof's ridge, and as such are invisible from the ground, which means that the aesthetic of your roof is maintained.
