how does airflow go from your soffit to the ridge vent if you have the foamboard flush against the purlins? I guees if it were me (will be soon as I need to do what you did on my garage) I would leave a gap on the topside of the foamboard between the roof so the air could flow freely from the soffits all the way up to the ridge vent....
Happy Thanksgiving, Phil! I built one building when we were building a house that was about maybe 12' by 12'. for a stove and refrigerator and a spot to go in bad weather. We were in what was left of a 22 foot Prowler camper and a 10 by 20 tarp over a picnic table. Laid the foam board on top of the so-called trusses and it flapped when the door was moved. That's why I was a driver/operator. Yall have a fine time and God Bless Yall and Thanks!
What’s the temp difference?

Nice clean look.
Great instructions and demonstration
