Hansen pole roof underlay. Between roof sheathing and steel roofing you do need to have something. My question is can i leave an air gap between roof and insulation as i plan on using r19 batting and covering with facing. 30x40x16 roof layers are metal synthetic underlayment osb 2 8 purlins. You may want to investigate a system including a ventilated roof mat as it will reduce thermal heat transmission.
Roof slopes are expressed as the number of inches of rise per 12 inches of run. A minimum of 30 felt should be used although synthetic underlayment would be just fine. Could you tell me the pitch of the roof for small pole barn front wall is 10 foot high back wall is 8 foot high rafter span is 13 feet. Dear pole barn guru.
Shingles and roof slopes less than 4.

Thank you mike the pole barn guru responds. I want to start insulating my pole building.
24 inches of rise in 13 feet of run would be a slope of 1 846 12 or 8 745 degrees.
