Neighbours new roof and rainwater discharge issues

[Stravinskykof]

Next door borders our back fence where they have a side alley, and we noticed today that they have put up a sloped corrugated plastic roof along it which projects to the fence line and very slightly over it. In other words its quite clear that any rain, especially heavy rain, will cause all the water from the roof to run over into our garden and into the flower bed below. Of course I know that I should speak to them first, but forearmed is always a good thing so does anyone have an idea of where I stand with this. It will probably mean that any prolonged or heavy rain will cause the ground / flower bed to become waterlogged and probably the fence will have water running down it also which wont be good in the long term.

Speak to your neighbour!

Legally, this could be a nuisance (in the legal meaning of that word), entitling you to take action for damages and an injunction requiring the situation to be remedied. But do you want to go down that route?

Absolutely, as I mentioned I know I should (and will) speak to the neighbour to ask if he had considered the consequences of the structure he has put up. We never know of course how people are going to react when issues like this are created and that's why I wanted to check on how I stand legally. Being in the middle of spending over £10k on a garden landscape project I'd hate to have an issue with waterlogged ground

Maybe running a plank down the top of the fence to deflect the water back, in effect, under the corrugated roof. That probably wouldnt go down too well. He should have put a gutter along it really, which could still be done but would be attached to the fence on my side ... which I wouldnt object to as the fence is covered by a hedge. However nowhere for the down pipe to go to.
I agree, neighbour dispute wouldnt be good - Ive only seen him once before in the 9 months we've been here as his house frontage is on a side road away from us
