I have a 1100 sq ft house that was built in 1847 but finished 15 years ago. Confused? It is a log home that has the outside  made out of the Nashville Maxwell House Whse flooring. Teddy Roosevelt walked on my walls. They are not the standard horizontal placement but stand vertical, 4″ thick, solid as a rock, and has a  rafter running the entire top of the wood around the house for support. The original owner/builder left 1 1/2 to 4 inch voids between these vertical beams and then put up on the inside 1″ foil stryro. and then drywall. I want to fill in the voids and since the battens are of all different sizes, cover this mess with cedar shingles. I suppose I can have foam insulation lightly blown into the voids; this would be no big deal since the underside of the house was never insulated and I WILL have it foamed in. The question. The outside on the “flooring” is rather rough and at odd angles. Can I shingle right over this or should I put up plywood first? Or should I use some of the newer products on the market now?
