I have recently had an underground drainage system installed around my house with ground level unlets for the downspouts to divert water away from the house. I have one gutter which I haven't connected yet, mainly because it is a first floor gutter, and to reach the inlet it would have to be extended to cross an exterior wall to the corner of the house where the inlet is. My question is in two parts: Can the gutter simply be attached to siding if all it is doing is transporting water and not catching it? How would I do that so there were no leaks in the siding? And...Would it be better to just put a long downspout at an angle to the drainage inlet? Or would that cause issues with debris since it would not be straight up and down?
