From what i ve learned here seal the seams of the osb roof sheathing with zip system tape to create an air tight barrier.
Putting down thermal on roof.
So you want r value on your attic floor and radiant barrier at the roof.
Metal is an energy efficient and cost effective roofing material.
Built up roofs consist of a base sheet fabric reinforcement layers and usually a dark protective.
If an open grid framed roof or widely spaced old solid roofing planks as the sheathing it is important to tightly stretch this so it does not sag down and hold water between the framing roof sheathing boards and the metal roofing obviously far better to put down a solid sheet sheathing first when doing a reroof in that sort of situation.
The resulting vertically oriented chambers can then be ventilated by bringing fresh air in at the boom and exhausting it out at the top.

Do you put the shiny side of foil insulation up or down on a metal roof.
