It is a 1957 modern home with cathedral T&G wood ceilings. At the last re-roof they added rigid insulation on top of the structure. I don't know if it is above or below the paper but it would seem to me that this would move the condensation point to where the sheathing is, causing moisture damage. Any other thoughts?

Improper installation of roofing shingles and rigid board (if that’s what that is). Those shingles that are lapped over at the edges should last about three years. Guaranteed to leak at those edges.
Recommend a professional roofer evaluate and estimate repairs of roofing shingles.

I personally would be ashamed to call that work mine. I can think of quite a few potential problems occurring from the insulation not the least of which is ventilation under the rigid foam. If the foam it’s self is not the proper type it will start to deteriorate very quickly, the shingles will start to dip and pocket, water will pool in small places on the roof etc.etc.etc. This is a boondoggle in the making.
