I live in the Northwest, and during the winter the crown will separate from the ceiling in some areas. Come spring, it moves back into place.
2 years ago I had my old cedar shake roof taken off, plywood sheeted the roof, and had a composition roof put on.
Now the crown separates in even more areas and with larger gaps.
We are starting to paint again, and wondering about if there is a way to fix this or a way to make it look better in the separation process?
