This makes the other point, much depends on the size and therefore the volume
of water a gutter can handle. A 40 foot length wants to be pretty big if you
get any amount of rain and particularly if the roof on that side is
particularly large just to carry the volume of water it will accumulate. Even a
steep fall can only carry a prescribed volume of water and the longer the run
the more resistance to the flow. A 2 inch square down pipe offers only 4 cross
sectional square inches of area to carry water away, a 4 inch by 3 inch deep
gutter can supply 12 cross sectional area square inches of water to that down
pipe. Once full, the gutter has to dump the surplus over the edge. If you add
the volume of say an 8 foot drop of the down pipe compared with 40 feet of
gutter one soon discovers how under sized the escape can be compared with the
volume the trough can carry.

When we moved into this house there was a 40 foot run of gutter with a down
spout at each end. If the rain was any more than light it would overflow in
the middle. We cured it by putting in a down spout where it overflowed.
