Tongue and groove roof deck

I am going to reroof a 200+ year old house that has tongue and groove roof decking. The beans are about 4' apart. I was thinking of using the plywood foam sandwich sheathing but don't know where to find it. Any opinions?>>>

I think that beans should only be about 8-10 inches apart. Giant pumpkins on the other hand need more room.>>>

What's wrong with the deck? Just tear off existing roof and install new one. Sounds like a perfect house for a tin roof. A historic house should get a new 100+ year roof. Not a 10-15 year shingle roof.>>>

Is the decking shot? Why wouldn't you replace the decking with similar decking?>>>

PS: Almost every log and timberframe home we built had a cathedral ceiling with T&G 2x6 deck. Before we started venting the roof, or installing metal, shingles would burn out in 12 years or less, in Ohio.>>>

Joe,

Think what you like, but as I said in my second post, I thought it was as simple as hitting a "2" instead of a "1", which led to the 28, when it should have been 18.

Iso R-values changed, but nowhere near that much.

I provided a link to the>>>

Builderr,

Did you do your own timerframing, or build from pre-cuts? We did Hearthstone log and timberframes. Loved the quality of the homes, unfortunately, because of the limited territory we had our market simply did not have enough people of sufficie>>>

Maybe, Joe.

But all my first post did was correct a wrong statement. It didn't escalate until I was so politely told to butt out, and invited to respond once I realized how wrong I was.

Shame on me.>>>
