Full Answer

Box vents, also known as louvers, low profile or flat vents, are one of the more basic types of vents. These vents are static, meaning they have no moving parts, which makes them easy to maintain. However, these vents are quite limited in their effectiveness, so it is usually necessary to install multiple box vents to fully ventilate a roof or attic space. To ensure these vents are most effective, it is best to install them as close to the ridge as possible.

Wind turbines are a slightly more effective type of roof vent, as these vents are not static, which means they contain moving parts. However, the moving parts are not powered by a motor, as the movement of the wind forces the metal blades to turn, which helps to draw hot air out of the roof space. One of the only issues with wind turbines is that some of the cheaper models tend to make loud squeaking noises when they spin. For this reason, it is a good idea to use a high-quality lubricant on the fan parts.

Power vents use electricity to turn a fan in order to draw air out of the attic, making them one of the more effective types of roof vents. There are numerous types of power vents available, some which are wired directly into the home's electrical circuit, while others contain their own built-in solar panels to generate the required electricity.
