We are looking into getting a standing seam roof. The roofing company uses ridge vents but only vents every third opening.
1) I'm not an expert, but I thought a continuous ridge vent (every opening) would be better. Do you know if that's true?
2) Do you know if this is very common; to vent every third opening?
3) How much less ventilation do you think this would create? We also have gable vents if that matters.
4) The opening on each side are offset, they do not appear across from each other. Would it create more venting if the openings were directly across from each other?
5) I attached a photo of a mockup of the ridge venting; do you see any problems with the design?
Thanks,

I am not sure why you would not vent continuous.
In any event, though, I am assuming you will have soffit vents as intake. Ideally, you want your amount of soffit intake and ridge exhaust to be balanced or, if anything, a little heavier on the exhaust.
The location of the ridge vents across from each other is not major -- probably a little better of they are staggered.
I am concerned about your gable vents. Provided you have soffit vents, I would remove the gable vents as thye will throw off the balance of the venting.
The mock up picture does not show underlayment beneath the roofing. I assume there will be underlayment in place.
Those are awfully large venting holes. I see mesh is being used to keep out insects. That is good. Is that a stainless steel mesh? probably not a bad idea for corrosion resistance.
I hope this has helped some.
Best Regards.

I think I would prefer to have more intake air than exhaust. If you have too much ehaust it will make a low presure in the attic and cause it to pull air out of the home around the light fixturs and any attic by-passes. Hot air in the attic will want to rise and make more pressure at the top(called stack effect).

I stand corrected on my earlier post. My apologies.
It is best to err on the side of more intake than exhaust.
Again, sorry. I must not have been thinking very clearly in my earlier post.
Thanks Nebraska Dave!
