home is 60 x 30 and orginally had two downspouts.
Plans were to put four but more and more as I look at it with no downspouts at the moment I want to put four on the back, not conventional but all could go into pipes in the ground to the ditch out front.
When I was thinking of doing the four coners a friend said you need 1/2 t 3/4 slop over the 60 feet. I said no makes more sense to make it high in the middle then down to both sides rather than side to side.
If I did put one on each corner and did go high on the 60 foot side at 30 feet the middle how much slope do you need? assuming that the home soffit and facia are level which I will have to check.
I think the size of the eves is called 5", it had two 3 x 3 downspouts on it.
Is my idea of putting four on the back stupid. I would put two in a few feet to catch the front and sides and go high in the middle then have two more in from the outside ones for that.
