When you take off an old roof. ... The old sheathing is boards. The
boards are old but they are tight next to each other. There is one roof
on
above.

Is there any reason to re-cover the old sheathing?


Your 1X decking should be inspected for rot, cracking, etc. The smoother
it is, the smoother your shingles will lay. If the boards are in good
shape, then new underlaymnet and shingles are all you need.

If the overall condition of the planks are bad. it might be easier to rip
them off and replace them.
