I had these gutters installed, and well they fucking leak everywhere. I realize the shingle is supposed to stick past the drip edge further, so idk if I can full blame the gutter installer. But they are some gaps inbetween the gutter and the fascia.

What are my options here, is there a drip edge available that will fix this? Can I move the bottom row of shingles down? Does the gutter need to be raised? It’s about 4 inches from the shingle to where the gutter starts. The roof is kind of on its way out but it’s not terrible. I thought of replacing the entire roof.
