Guttering advice

[Creamegg18]

May I get your thoughts on whether there’s a solution to somehow get some sort of fitting to the gutter part as circled in photo to connect to another pipe, so when it rains, the water goes to the gutter instead of pouring onto the roof.

Not sure if existing fixture will cause an issue for the roof especially during heavy downpours or asthe roof ages. A few roofers were unable to find a solution due to the angle of the gutter. Surely there’s a part that can connect to the blue circled part to some pipe and connect to the other gutter? Thought’s appreciated. Thanks

I can’t imagine there is a downpipe to downpipe connector in existence tbh (in the way that a downpipe to water butt connector works) because it shouldn’t need to exist. Downpipes should go down and discharge somewhere already without needing to go to another downpipe iyswim.

Is that other one actually going through the roof? Isn’t there guttering on the edge of that roof to catch the water from the other downpipe anyway? Could the roofers not reassure you that the way it is now isn’t going to be an issue? I’ve seen a few that have downpipes discharging onto roofs in that way, I would hope it wouldn’t be an issue or surely they wouldn’t do it.
