Post ---------- A flat roof covering an addition to my house had to be completely re-done from the walls up--new rafters, decking, roof. I had it framed, decked, and re-roofed by a roofer, but I must finish the inside.
Maybe if I can describe this properly, no photo will be necessary: The rafters run from the inside wall and rest upon (and extend beyond) the outside wall. There is plywood decking with rubber roof on top. No soffit yet. So it is completely open between the rafters from the soffit area, above the walls, to the inside. I will insulate the inside room area between the rafters. I will have vinyl soffit and facia applied later, and the soffit, will, natrually, be vented.
The question is how should the insulation be separated from and protected from the soffit area which will be vented to the outside?
Seems to me that I should nail up some planking or staple up some plastic (at the walls between the rafters) to protect the insulation from the outside air.
Or, should this be left open for ventilation purposes?
