Upper gable gutter discharge onto roof not lower gutter

[chaoticj]

Hi,
I've had all the gutters and downpipes to the main house replaced - previously plastic/cast iron mix.

The new gutters are 5" seamless aluminium in a Victorian style and downpipes 68mm cast aluminium.

The upper part of the side gable was previously a rotten wooden gutter with fall to the roof edge and cast iron offset downpipe which carried the water down to a plain pipe end on the last slate of the lower roof.

The fitters did not install an offset downpipe and had the new gutter with an opposite fall to before - back onto the roof. I asked for it to be changed back to how it was as not happy with all the water that would be running backwards onto the roof over the slates/eaves/flashings etc.

It's been changed and now falls away from the roof again, but the offset downpipe isn't at the very edge of the gutter and the offset downpipe drains onto the lower roof via a shoe.

I'm told this is because it isn't possible to dress the pipe into this type of gutter. The way it's now been done, the shoe will harmlessly dissipate the water over the roof - if it was nearer the edge, with the amount of rain we get these days, then water could overshoot the gutter.

Does this sound/look ok? Attached picture of how it was/how it is now.

Thanks in advance..

I would have done away with the pipe and had the gutter flow towards the house main roof. It’s only a short run. It would have dissipated on its way down before reaching the lower gutter and there would’ve been no splashing.

Must be a simple solution for someone in that game!
