Not necessarily...

I would first have made my way into the attic to see if there is a "chord" (not rafter) that is broken or maybe altered. In which case, would not be good (SE required).

Since that 'wavy' section is at the transition of the lower ridge and the truss of the right hand slope, there is a good possibility that the wavy section was the result of mis-aligning the lower trusses.

It's just too hard to tell without any pictures from the attic side.
