Re: Gutters being installed - problem?
First, gutters are not installed parallel to the roof unless the roof is lower on one side than the other. The low end will be the end where the down spout is located. If you have a narrow facia the gutter may hang down below on the downspout ened. It needs to be slanted so the water will run to the downspout. From your picture I can't see the whole gutter.
Second gutters usually run 1" or 2" past the end 5" or 6" seems excessive. It's your house and you don't like it, it should be there resonsibility to cprrect it. JMHO.
