Hi again folks.? Several days back, Dave described an improved method of adding rain gutter gutters.? I would like to install a set.? ?However,? I'd like a further description of where the gutters are placed, whether the angle aluminum is mounted with the perpendicular section up or down.? ?Is it mounted flush (in line with the roof edge), or is there value in mounting it further down on the aluminum roof extrusion?? ?I do see the value in extending the gutter ends out from {wider than) the roof, and adding a diverter (as in Dave's original installation).? Thanks in advance.....I want to do this right.? ;-)
