I’m looking for a ridge vent to install on my home. I’m only interested in the rigid designs so I can install a historic sheetmetal cap over it. Somewhere I heard that you want to use ridge venting that has a “lip” in it so that the air is deflected over the vent. With the air passing over the ridge it would then creat the necessary suction to draw the air though the cavity space. I believe that this may have been a ASHRAE study, but I’m not sure. Is anybody able to reinforce this rumor with fact? Any advice for me?

I've used Coravent in applications like the one you describe with great success.
http://www.cor-a-vent.com/
Yes, cor-a-vent is one of the manufacturer's that I'm considering. I know that their x-5 system (with the flip vent) is good for harsh weather conditions, but does the vent function in light winds? The vent supposidly closes at 20mph. Guess I was wondering if the vent performs like the typical ridge vent (ie doesn't work below 20mph).
Do you have soffit vents below?
Yes, when I replaced the roof soffit vents were added.
Good, just checking.Excellence is its own reward!
How did Prospero allow a clone?
Your login name has to be unique. Your nickname does not have to be unique. That's one reason I'm Uncle Dunc here instead of Bruce.

And what's wrong with Bruce??????? {chuckle}
Nothing wrong with Bruce. It's just that the voices told me not to use my real name here.
So we share something in common.
when calling in sick say the voices told me to clean all the guns. Stolen from the voices thread.
we've researched a lot of the claims and followed the topic since the early '70's... if you're going to use a ridgevent.. the best is Shingle Vent II by Air-Vent.. which is now a Certainteed Company..
but hey , whadda i no ?

Yes, I have a sample of the shingle vent II. In fact it was the vent that I designed the ridge roll profile around. The sloped vent was causing me some grief though and I was hoping for a alternative. Guess that if this is the profile that I should be using, then I'll just have to deal with it.
I have nothin under my metal cap, for a ridge vent just a hole. Had an hurricane yesterday with 20 inches of rain with wind. attic stayed dry.
