Catching valley's flow off diagonal roof
A dormer over our front door diverts rain to the dormer's sides, from where it proceeds down the slope of the main roof. On the left side I think I can catch the flow off the roof by installing a gutter. I have a horizontal eave to work with, and can move water along the gutter to a downspout farther left. How can I catch the flow off the right side? There water from the valley at the sloped base of the dormer shoots out off the roof in a stream. The eave for that section of roof drops diagonally, sloping down to the left.
