I am restoring an 1842 colonial in Connecticut and am currently working on a second story front porch. The floor was covered up with asphalt roofing and is slightly pitched. After ripping it off, I discovered 3/4 of the floor has T&G flooring (looks like Doug Fir)and 1/4 is just plywood.
I would like to put down new flooring. I saw some other postings that talked about floors buckling over plywood. Would I have to rip out the entire floor and start over?
Also, can I use engineered flooring (glue or nail or both) or should I put in new T&G and stain/poly?
thanks in advance for the help!
