How effect is a cold roof with a Boston ridge if there is several feet of snow on top of the Boston ridge?

To prevent moisture buildup and improve performance, install a continuous air barrier—such as drywall or specialized membranes—under tongue-and-groove boards or other interior wall paneling.

funny you should ask. I made one here. I don't think snow would affect or effect it at all, so longs the vent space can vent and no conditioned air is venting out carryin moisture.
is it screened? windows? are we talking the same hound here?

Sensai,
What in tarnation is a Boston ridge?
Picture this..I can't draw it w/o a hernia.a boston ridge is likea long cupula ..or coupoula or a chicken house vent..gable to gable...a short knee wall on the existing roof plane and an added ridge above it..lemme see if this 'puter has the pic..my other one is still DOA.prosp. is fubar..hang on.

I think my 'puter has a 'senior moment" lets see here...nope..can't do an attachment...this is fubar. not my end, it's propensity for despairo that's locked up like a bulls ####.

Got it.... no need for the pic. Didn't know that's whachacallum. Thanks
There is another name, but not that I can remember right now

Hey rez, ain't you one of the folks always telling us to resize our pics? That was a 300K'er. the dial-up'ers won't be happy.

Well, ya that was aimed at Diesel and I wasn't sure the small type would show up. However, the photo shot was scaled down a bit for the dialups.
But point well taken.
Somebody go tell Jaybird 800kb's a rough road for anybody to ride. Roar!

Just between you and me, I don't care if a pic is large as long as its a clear shot. The larger file size ones tend to show a lot more detail. But I ain't all that keen on dl a 500k blurry pic.
And besides which, I couldn't miss a chance to give you a hard time about something :)

I take it you are not on dialup and instead are cable /dsl.
The only reason anyone recommends keeping files as jpegs and under 100kb is to provide easier viewing and faster download times for the dialups.
Often times the file is just to big even if the dialups wanted to wait the 10 minutes for the download.
There are a goodly number of folks that post or lurk here that are unable to get dsl where they are located.
I view it as a kind of forum etiquette thing that really doesn't involve that much to apply.
Once one learns the basics of downsizing a file it can be done quickly in less than a minute or so just following a series of clicks and picture quality isn't altered that much in most pics.
Some posters have taken it upon themselves to present both a large and smaller KB file if it is desired to convey detail in the presentation so everyone has access to the post.
It's no big deal. No one is going to wrassle you down with a headlock and draw blood if you post big KB files.
Well, then again, sometimes one can wonder what some folk on here might be capable of if the opportunity presented itself. Roar!
be a little kb

Depends on where I'm reading from. Sometimes its fast, sometimes is dial-up. And yes, i think the folks who post both big and small versions of the pics are to be commended. Covers both the high speed and slow speed. I tend to just post small ones myself.
But if you wanna see large file sizes, go wonder over to Knots. Wheeew! 600k-2mb files aren't all that unusual. And they're not big to show detail, they're big cuz the poster didn't shrink them. ha ha, nothing like spending 10 mins to dl a blurry-#### picture of an endtable.

Lstiburek and the guys at Building Sciences say that situation is proof that ridge vents don't work and/or aren't needed. My take is that if you're losing heat into the attic, the warm air will rise to the ridge and melt enough snow to get out soon enough. On the other hand, if it's so cold the snow on the ridge isn't melting, then none of the rest of the snow is melting, either, so you don't have to worry about ice dams, which is why you wanted a ridge vent in the first place.
Again, thank you.I am fiddling with a complex area..heating/cooling is almost equal ( I think)..
I wish it was a simple 'we are in a heating zone" or not.
your persistance and vigilance only rivals REZ's.I should post this in the Tavern thread, about the bestist of 04. I will.

I think you point regarding the snow no melting is proof that they are working and/or are not needed. My question is, does a cold roof work as well without the Boston ridge?
Well, I'm no expert. Maybe some of the guys who have built cold roofs will chime in here. My intuition is yes, any kind of ridge vent will do as long as you have the proper balance of intake and exhaust vent area.

I thought Lstiburek/Building science recommended Boston Ridges in cold climates when one builds a cathedral ceiling?

My take on a boston ridge is that they are better at keeping ventilation going when the roof is covered with snow than any of the commercially available strip vents
You may be right. I may be slandering those guys. But I've definitely seen somebody posting here arguing strenuously that cold roofs don't work because they stop venting when the ridge is blocked with snow. If it wasn't Lstiburek, et al., my apologies to them. And to you for misleading you.
Kstiburek from what I have read believes in cold roofs. Whoever said they don't work if covered with snow needs to come out to my area. Right now we have several feet of snow on most roofs and I have not noticed any ice damming on a cold roof. My original question was answered by you, I believe, when you wrote that since the snow is not melting they cold roofs must be working which makes sense to me.
Unfortunately your comman sense destroyed my business idea for some sort of fan and/or heater for ridges. I even have several million dollars of my profits already spent! Bummer.
