My apologies for the poor photo. I have a new roof with several voids along the rakes due to the differing thickness of architectural shingles. My roofer says it isn't an issue with regards to rain and moisture due to the starter strip, remains quiet when I raise the issue of wind, says there is nothing he can do, and calls me picky. It would appear to me be a moisture and wind issue which could be corrected by ending the course with a portion of shingle the same thickness, but I'm not the professional. Can you please advise?
