The air is still moving in this case regardless of the side that is cut. Its supposed to be cut on both sides though.

Ok, my question is if only one side is cut is enough air moving? I kind of had a feeling it was supposed to be cut on both sides.

Instructions usually call for being opened on both sides. Have they installed the actual ridge vent yet?

I'm sure he will have an excuse but you want to see the mfgs instructions and make him follow them. We can review the required amount of ventilation you should be looking for.

Add your nearest big city to your profile so we will have an idea as to your climate abd building methods.

Bud, thanks for the reply.

Yes, they have installed the ridge vent, shingled over it and are done with the job.

They supplied the vent so I'm not sure what brand or what the manufacturer's instructions say.

I live in Cincinnati, OH

I agree suppose to be cut both sides. Is that felt we are looking at or the ridge vent? I’m not a roofer but have been in hundreds of attics. I’ve never seen one cut on just one side

The black that you see is the underside of the ridge vent.

Thanks for the link with install instructions. I will contact the contractor and see what he has to say. I would much prefer that it was cut on both sides. Good point about not just venting hot air but venting moist air in the cooler seasons.

I paid the last part of what I owed them when they finished up last week.

What do I / we need to do to determine how much ventilation I need?

They usually cut both sides, that does not look cut. They may have found a joint there with a small piece on top that they just removed and maybe that was bigger than they usually cut. It will work just fine.

It's definitely not cut on both sides. According to the instructions Bud linked me to there is a 1" minimum cut needed on both sides so maybe like you said they cut a wider gap but I'll have to get up there with a tape measure to check.

Good point about if a claim would need to be made and my warranty, whatever it may be, would be void if it wasn't installed to their specs. I'll have to contact the contractor, find out what kind it was, either call or look up online what the install calls for.

My house was built in 1966, it's a 1360 square foot ranch. I don't know anymore specs than that off the top of my head. Do you need any other information?

 

[pindude80]

I just took a measurement of the cut width.

What kind of warranty claim would be possible, the vent itself being faulty or damage caused to the roof because of the vent?

 

[pindude80]

. Also, the suggested NFA is not a hard number in that 10% short and you will have a disaster. As long as you have low vents half of what you ended up with would work.

What are low vents, sofitts?

I am going to call the contractor. I know I would definitely feel better if both sides of the ridge were cut. I am going to bring up the warranty thing. What type of warranty problem would we have, with shingles or with the vent?

 

[pindude80]

I think your approach might be better with your contractor to tell him the wood is supposed to be cut on both sides. And that you want it done proper. If you tell him you will feel better if it would be cut then you might have some issues. It’s going to cost him a few dollars but not too bad. He can reuse the vents but will probably have to change the shingles on the cap itself. Hope it works out for you. A good contractor won’t blink an eye about that. Most likely someone on the job is going to get some slack, rightfully so. Having any documentation from the manufacturer liked mentioned in a previous post would be good to have.

Yeah, I'm going to tell him I did some research and everything I see says that it's supposed to be cut 1" minimum on both sides. I also want to bring up the warranty thing and then get into asking what the instructions say and if they didn't follow the instructions the manufacturer will deny a warranty claim.

Can he reuse the vents? I thought someone earlier in the thread said that they couldn't reuse and have to buy new. It's probably ok, but they didn't install a ridge vent on top of my garage and I was thinking maybe that is because it shares the same attic as the rest of the house?

Hello, is it possible that you have a lower pitch on one side, for instance i have a 2/12 pitch on back side and 6/12 on front side im having same problem

Nope, the pitch is the same on both sides of the ridge.
