Turbine type vents may be electrically powered or they may turn as the wind blows. A turbine has a series of vanes that spin as wind passes through them. The wind rotates the fan blade causing air movement in the attic as air is pulled out through the turbine and replaced with outside air. The sun does that.

These can be ridge vents wind turbines or the flat vents your roofer wants to install. Good attic ventilation is important for preventing ice dams in the winter.
