Here is a house (see the pic) originally built somewhere within 50 miles of Minneapolis.
Plans are available for purchase, and I might build it someday. Not for me, but either as a spec, or on contract for a client.
But I digress. We’re talking venting and insulation here.
Minneapolis is snow country, right? Probably not as much as snowy as where I might build it in these here high peaks of the Adirondacks (85 psf ground snow load), but it snows there in old Lake Woebegone country, it’s just gotta. They couldn’t have attracted all those Swedes and Norwegians if it doesn’t.
So here is a 100 percent cross gable roof, with all of its snowmelt coming down equally in four valleys. Ultra high potential for ice damming.
We had better either have a perfectly vented cold roof, or a totally sealed hot one. But, as you can see, there are no eaves.
I raised this question long ago, and tried to have you guys help me through the thought process of venting.
But the more I look at it (haven’t bought plans yet . . . not yet in the budget), it seems as if we will have to urethane foam the whole thing, ice and water the heck out of the valleys, and forgettaboutit.
Right?

Where can I find the snow loads by zip code for NYS? Cool looking house. You could always frame the roof 100% LVLs and do studs 12in on centers and it should hold the 85!
I would certainly urethene that one.
I think I remeber discussing this design with you but pertaining more to structural framing issses.
