Is ridge vent needed on non-attic/vaulted roof?

Hello All,

I've seen the threads regarding ridge venting on homes with attic and/or truss spaces that should be ventilated. My home, however, is all vaulted ceilings consisting of 12' deep rafters with drywall on the inside, batt insulation directly behind that, and then an air gap between the top of the insulation and the underside of the roof sheathing. When new, we installed both eave vents and ridge venting, but the ridge benting we installed has been problematic and I am wondering if it's really necessary or beneficial for this type of roof. Any advice or guidence would be much appreciated. Cheers!

Soffit and ridge venting is needed.
What style venting was giving you trouble?
Was it roll venting? That stuff is useless and does not allow enough venting.

Thanks for responding. It is the plastic type that had a feeble thin strip of foam on the edges. Occasionally water gets in when its windy while raining. The reason I asked was because I onlt saw reference to it being needed in homes with attics. If that were the case, I'd just remove it, fill in the gap in the sheathing and shingle over it. Otherwise, I will replace it with a metal ridge vent. So you're sure it's needed for a vaulted roof as I described in my original post?

If you don't have the ridge vent, condensation will form and create mold that, over time will become visible on the in side of the drywall
