When I install the roofing on my house, I am planning on continuous soffett and ridge venting. I have always heard that a continuous ridge vent, along with adequate soffett vents, is the optimum passive venting method.
On Roofing.com, however, I came across this link, http://www.savenrg.com/venting.htm
, that says ridge venting doesn't work.
Of course, the article is by a company that's advertising its own venting product, so there may be some bias there.
Basically, what they seem to be saying is that because ridge vents or ridge trims are shaped like an inverted 'V', that they block the hot air from escaping.
What's the general consensus on whether or not ridge vents work ?
