Angry Ridge Vent & Power Attic Ventilation Fan?

Two story house on L.I. Roofer says my powered attic ventilation fan has to be removed for installation of ridge vent with new roof. They do not work together. Is this true?

Your powered fan, when on, will suck air into the attic through the ridge vent - defeating their purpose. The ridge vent works on thermodynamics - hot air rises - escaping through the ridge vent, creating negative pressure in the attic which is then equalized by fresher air coming in from the soffit vents.
