I have recently purchased a gambrel style pole barn house. Unfortunatly it was poorly built, and I am having to fix quite a few odd problems. I am a painter by trade, so this is often a learning endeavour for me. My current problem is my roof. It consists of sheetrock, 2×6 rafters w/ unfaced fiberglass, 1×4 nailing strips, and metal roofing. I need to find an economical and expeditious way to provide ventilation, and block insect infiltration. Any ideas?

What are you trying to ventilate? Attic, Bathroom, Sinlge room, Multiple rooms, or the space between the insulation and the metal roof?
Hey, thanks for your response. I am trying to vent the space between the insulation and the metal. I live in western montana. Its cold in the winter and plenty hot with very long days in the summer. I can feel the heat radiate to the interior of the house in summer and the flies and wasps are out of control. There is no air flow through this space
The spray foam is the absolute best choice for what you are describing. Other option is tear off the roof and sheath, then paper and replace your metal roof which probably won't be reusable.
The foam you can squirt right onto the existing purlins & metal. No more condensation, no bugs either if you put something in to block whatever opening you have at your wall/roof junction. Soundslike it's open? Joe H
We're not supposed to be starting another vent/no-vent flame-war until at least the first week of March. Don't you guys care anything about TRADITION!!!!
Take this thread to Fusco's site. Oh that's right, he shut it down. Alright, Quittin' Time then. Darn, they're all Pacifists. Oh well, here we go again. ;-)
Damn the torpedos, full speed ahead!!!!
They sell eave vent "plugs" which are installed in the roof eaves. Just drill a hole of the same diameter as the "plugs". Then you plug them in snuggly. I beleive they come in 2 or 3 dif diameters. The air will flow through the eave vents and escape through the gaps in the ridge cap/ roofing connection, because the ribs of the roofing don't permit the preformed ridge cap to be tight to the roofing, .
What climate? How big a building? Best solution? Tear out the ceiling and fiberglass & spray it with spray foam. Look at some of the info here--------->

in some cases the best is to vent.....in some cases the best is to seal everything.
You need to do lots more research.
