File corruption when sending to layout

[Ray Bartsch]

When I need to send an elevation to layout, or even to a CAD Detail, I have been experiencing some file corruption. Please review the attached images. It seems as though some end views of gables show through rooflines, and shingles are getting messed up as well.
Do I have a layer turned on that may be causing this?
Any help would be appreciated.
