Good attic ventilation is important for preventing ice dams in the winter. To the untrained eye ridge vents can be almost invisible. Most effective ventilation uses a ridge and soffit continuous ventilation system but even these designs can vary from roof to roof. They get a bad rap because they are almost always installed incorrectly.

When connected to the thermostat they can turn on and off automatically depending on the current household temperature and the specific settings. I do agree that static vents would work fine if your roof design allows for them and you should always follow some basic rules of attic. Static roof line vents are effective for ventilation but generally aren t recommended due to issues with leaks. Roof louvers gable louvers wind turbines and power attic ventilators are all visible exhaust vents that are mounted on the outside of your roof.
