Scott in georgia is on the line with a question about attic ventilation.
Ridge vent vs attic fan.
Without any air movement temperatures in the attic soar in summer and plunge in winter.
And then the vent fits on top of that.
Now for the other sections of roof and attic that are again separated from that garage space there you should use a continuous ridge vent.
Joe blanco posted in general questions on february 21 2016 01 26am is there any advantage in using an attic fan comparing to ridge vents.
One other thing to consider is that if you already have a ridge vent placing an attic fan too close to it can cause the vent to start drawing in air rather than letting it out.
However the roof is only a 2 12 pitch and i am wondering if the shallow pitch will have any adverse effect on the vents.

Without ventilation unfinished attic spaces can end up having stagnant air.
And be careful with the type of vent that you.
And the temperature in the attic gets to be somewhere around 115 to120 degrees during the summer and it gets pretty warm.
If you have suitable intake venting a ridge vent might be a better choice while larger attics and those with poor ventilation might be better served by an attic fan.
Well i have a house that has a ridge vent in it.
At one point on the roof it is about 30 from the soffit to the ridge with a 2 12 pitch.
Make sure the ridge line is cut open at least an inch to an inch and a half so you have a good wide gap at the top.
Also since the fan is powered by the sun it should turn off when the sky is overcast during a storm which will keep it from drawing rain into the attic.
When you are deciding between a ridge vent or an attic fan consider the needs of the attic.
Since your solar vent fan only moves 500 cfm a third to half that of a typical hardwired attic vent fan it probably won t move enough air to reverse the action of the ridge vent.
I have been doing some research and it seems like the best way to go is to use soffit ridge vents instead of an attic fan.
