Per :
Two of the roofers say to go with ridge vent on both of
these roofs, get rid of the existing power fan.

One roofer insists that I should stay with using fans on
the two roofs as it is now. His argument is that a power
fan moves a lot more air than a ridge vent system can.
Climate is NJ.

I am about 23 miles west of Philly.

We had two installs of power fans: one was in the roof facing upward and
the other was in a "window" in one end of the attic.

Never again. The noise/vibration was not worth any increase in
effectiveness.

With the roof mount, I mitigated it somewhat by detaching it from the
roof and hanging it on bungees... but it was not enough of an
improvement for me.
