I've never seen anything like this done by a carpenter. Only from pictures it is not possible to judge what can be done or saved. But as it looks, it must be done again properly. Lateral the bricks away and the lead custody also and then down to pull a proper sheet metal custody attach and then the bricks clean up to the dormer. If the dormer is covered laterally with sheet metal, you can only clamp felt behind it, but since you have to do it right again anyway.

What makes me a little worried (not to see properly in the pictures) is the whole statics of the dormer and the damaged statics of the old roof. So you don't build in a change and the load transfer from the rafter to the change takes place how? Here I would call in a specialist that looks really dangerous to me (also because of snow load)
