We have a cabin that we'd like to insulate significantly more than it is now. I'll start with a question about the roof, then post separately about the walls.
The roof has no insulation at all. It is a tongue and groove wood which is nicely exposed on the inside of the cabin, then covered with tar paper and shingles on the exterior.
I want to get that changed from no insulation to a very high insulative value.
With no experience at all in home construction, the way I picture this happening is to remove tar paper and shingles from the roof, add framing on top - with enough space to lay down some type of insulation material - then add sheeting over the frame and insulation, then re-shingle.
Is this the correct procedure? If so, what are details of the framing and what additionally should I consider for the project.
Thanks,
Martin
