Roofing course pics and comments

The attached pictures of the roof shows several problem areas. The home is facing east however there are several large oak trees and this side is mostly in the shade. There are several shingle tabs that have lifted and curled(very minor) i believe becaused it is in the shade and retains mositure. The front of the dormer has not be flashed properly, shingle go to edge of back flashing but water can go behind shingle. Also the flashing on the side of dormer(hard to see flashing) however there is a large amount of black sealant down the rake. See attached photos
