Ridge vents for corrugated metal roof?

I'm installing a galv corrugated metal roof on my shed and am having difficulty finding a ridge vent. I know at least several companies make ridge vents for standing seam and similar roofs but I have yet to see anything for the old fashion corrugated stuff. I would prefereably like to have one with external weather baffles such as what Air Vents by Certainteed have. Of the data I have looked at, these seem to create the least amount of preasure near the top offering the best air flow under a variety of conditions. I called Air Vent direct hoping to gain info on whether or not one of their vents could be adapted to corrugated roofing. To make a long story short, I could not get anyone on the phone that knew anymore than what they could read in the technical manual which I have. I asked to speak to anyone there who have handled these or perhaps the engineer but to no avail. Anyhow, I have asked this same question here in the past and it was suggested I use the vent the roof maker suggests. I have checked in to this and ran in to pretty much the same as what I did at Air Vent. The building supply store selling the roofing had no info and neither did another which I talked to. Does anyone know if there is a ridge vent adaptable to corrugated metal roofing or if one of the Air Vent filtervents will work? Surely someone makes a decent vent that can be made to work with this style of roof. I have looked at Cor-A-Vent but they use an internal baffle. If you'd prefer to email me direct, my address is [email protected] Your help would be apprecitated. Thanks, r

I would not use a "generic" system. At the very least, the metal covering over the ridge vent should be the same metal as your roofing is produced from. Differential weathering, otherwise, could create a very ugly situation over time. Have you contacted the manufacturer of your roofing and made this inquiry?

"I would not use a "generic" system. At the very least, the metal covering over the ridge vent should be the same metal as your roofing is produced from.

But, if I did get some "differential weathering", I wouldn't feel at all bad as the architecture and other finish's will lend itself to contrast. "Have you contacted the manufacturer of your roofing and made this inquiry"? To an extent, yes. I will continue to invetigate though. Thanks for the response.

To an extent you have chosen a commodity type vertical rib sheet that is supplied with the basic accessories. There are a number of component companies that make vented closure strips for most common profiles which you can use to then install any metal ridge cap allowing it to vent. I would try this. Go to metalmag.com, metal roofer, moderntrade.com to look up advertisers of these products.

"There are a number of component companies that make vented closure strips for most common profiles which you can use to then install any metal ridge cap allowing it to vent. I would try this". Thanks for your repsonse and links Alan. Unless I'm terriblly blind though, I still can't find any one ridge vent or combination of pieces that are listed as being specifacally for or adaptable to the old-fashioned corrugated metal. I can see how one could rig something very basic and simple without too much difficulty but, I'd much rather have something that was a little more weather worthy...namely something with external wind baffels. And to do this, or have it custom made, would be far more complicated than I care to make it. It is just hard for me to believe there isn't something out there but I have searched high & low. If you, or anyone else could direct me to a specific link to what I describe and it says the product is for this purpose OR can be adapted, I will make a public statement that I am blind and will promptly make an appointment with the optometrist.

AirVent's aluminum filtervent products should be able to work, provided you can find a solid closure strip which meets the profile of your roofing. Another option is to make a metal closure strip and then seal it to the metal roofing. As you say, though, this gets a little complex.

I know this is an old email thread but did anyone ever find an exact product for a ridge vent for a corrugated metal roof, and if so what is the web link or other contact info?
