Would you trap moisture foaming roof?

If you pulled a tractor or truck covered with snow inside pole barn and the roof has been foamed covering up all ventalation, how would you get the moisture out of pole barn? I'll post pic below.

When the NHDOT built a new shed in out town 15 yers ago it was designed partly for melting snow off the plow trucks. It has a heat exchanging ventilation system for removing the humid air. If you want to preserve your building and contents you have to get the moisture out.
 
I would think the majority would drip on the floor and run out, soak in, or evaporate.

What evaporates will condense on the coldest surfaces until it finds it's way out.

The coldest surface will probably be the tractor itself until it acclimates to room temperature.

One thing about the well insulated ceiling, it won't be dripping as bad.
 
open all doors to let the air flow through. fan will help. i have small building that I run a dehumidifier in it all summer. catch the water and put it in containers to use for battery water and use it to mix with antifreeze if need be. circulating air will dry it out. time wise depends on how much air flow and temperature.
 


If the snow melts and the building is sealed, the moisture will stay there in one form or another. If you ventilate it, the moisture will exit over time.
 
Why would you close off the ventilation areas, or are you referring to unintentional gaps and cracks in walls and eve areas???
Back when I was contracting I built several all steel buildings and utilized open cell spray foam,plus a 2"thick insulation board with a 1 hour fire rating with excellent results, but the buildings also had a dedicated venting system.-------------Loren

In the pics you can see the spray foam applied between the girts and the Dupont fire retardant insulated panels applied to the inside of the girts.
 
Heated or unheated?? If heated the heat it self would take care of it. If unheated then moisture would prety much stay unless you opened up and doors for a few hours on a warm day
 
I want to have open air ventilation. Let mother nature keep it dry. I'm thinking of metal roof with 1 inch foam as vapor barrier on ceilings only. Leaving eves and ridge open to vent.

Walls 14 feet. The cost to cover foam will be more costly than 30 year shingles.
Vapor barriers commonly used are combustible too and no one covers them.

So which is best vapor barrier, bubble wrap, fan fold or 1 inch of foam?

George, having open air ventilation in Indians in the winter means that you remove the moisture from the building by pulling the snow covered tractor or truck back outside.
 
Why pay to insulate with 1" of foam then leave eves and ridges open?

If you just don't want roof to rain in an unheated/ventilated building, put plywood or roof underlay under your roof steel. Or spray a 1/4" on it. Doesn't take much, a layer of almost anything will stop it.
 
If you are looking to only control condensation on the under side of the roof, buy
Grace roof wrap or equivalent and roll it out over the top of roof perlins and then
apply your steel roof.---------------Loren
 
Ever since Tyvek/house wrap has become common it is a good product to put under metal rooves. The trick is to get it tight and in line with the metal so that any moisture will follow the angle of the roof.
 
I am guessing what we use is what you are calling bubble wrap. I use two product called micro=foil. Has tin foil on BOTH side with a layer of bubbles in between. Really works well around here. Earlier version was white plastic on one side and tinfoil on the other but the double tin foil really works and no bird problem.
 
Not exactly. I can park a snow covered
vehicle or tractor with snow in my pole
barn with shingles, eve vents and ridge
vents. In a day or two everything is
gone. Even in winter. I can speed up
drying with a small box fan. Been doing
this for years.

IMO, building need a breath, be vented.
 

Geo, I may be wrong but it appears that you are playing coy with us. You don't say whether or not it is heated, and since you are talking about insulation everyone is assuming and answering as if you are talking about a heated building. But it is looking to me like it is not heated, and that your concern is moisture not heat loss.
