A friend of mine is having a water problem; the water is coming down behind the gutter. It turns out the drip edge isn't covering up the gutter completely on the one side for a considerable length of the house, as the gutter slants downward. Is there a way to fix this? Is there a flashing you can use, or something else?
Note that this started happening after a recent replacement of a roof. I've included some pictures of what this looks like.
