We also had them remove an attic fan that we never use, it was just one more hole in the roof for a future leak to happen. Ditto for a satellite dish on the garage. Redo all the flashing, peak vent like yours, etc. And we upgraded the shingles to Certainteed Landmark Pro, in a color that is Energy Star for reflective properties. Because we only have a single zone A/C the upstairs can get a bit warm in the summer, these shingles supposedly reduce solar absorption by 35-40% which I figured can't hurt.
