Shingles and gutter install

I put a new roof on my home about a year ago. I had never done one before and I didn’t have anyone to help. Anyhow, I need to redo my gutters. But, I did not leave over hang. Is there away I can correct this without roofing the house again? I also could use some advice on how to correct the side edge. Doesn’t look right to me and I don’t think it will last long.

It’s fixable but not easy and you may want to hire a professional. You have to add a short course at the bottom, which involves pulling nails on the first course.
