I know this is DIY, but I have too many project and hired someone to do the gutter install. They did a great job, but I am concerned about one area in the photo below where a gutter comes down on the roof. I would have preferred the upper gutter to empty directly into the gutter below. I think they were trying to keep the down spout away from the window. Is this ok or should it be changed to empty into the lower gutter?
