Neighbours run off - wrong or right?

[beard79]

Morning, Peeps

Did have some minor damp/mould issues in our bathroom last few years after it was remodelled and with the kids shutting the window before turning it into a sauna put it down to a bad design or something..... it was nowt serious just annoying

We also had an overflowing gutter with a couple of dodgy joins. I found someone to sort it and they stopped the major leak from a join which was above our conservatory and removed a join which was by our bathroom and the damp issue seems to have been resolved noweven though we are still getting some leakage

However, whilst they were doing this gutter maintenance they raised a query and something I'd never considered....

Our Neighbour had a loft conversion with rear dormer (we are mid terrace) a few years back and the fall of the gutter in their direction is not as good as it could be. He thought where they had their gutter fitted post conversion it was possibly higher than originally and would of inhibited flow to a degree leading to the overflowing maybe

BUT
what he did query was the run off from their dormers flat roof as it is projected straight over our roof - see image attached

All other neighbours with same conversion have two downpipes coming down the front each side of the dormer into the gutter whereas this, when it rains hard, chucks water across ours and we do still getting some overflow leakage from the gutter.

Is this okay to have the spill coming over our roof like this or does it come under some sort of nuisance law?

Cheers muchly

Tell them you are not happy about it and want it altered...

I agree, that is very wrong. Under heavy rain, the water will be projected at the edge of your tiles, rather than down your roof, where it will be less likely to be a problem. Even so, under heavy rain, the speed and flow, might overcome your gutter's ability to prevent it over spilling.

Why has your neighbour decided it's fine, to dump their rain water drainage onto your roof, rather than onto their own, at the other side of the conversion - or is it a full width conversion?

You need to have words with your neighbour, and explain that dumping their water on your roof is not acceptable. At the minimum, a hopper needs to be added, at the end of the gutter, and a fall pipe leading down to discharge into their own gutter.

It is a full width conversion. TBTH she (neighbour) is most probably oblivious to this and has no clue. I didn't ever consider this until getting ours sorted but before I caused more & new agro between us just wanting to check I'm not being the arse

How long since it was done, was permission asked, and given for that?

Being very honest its well over five years and embarrassed that I never realised the gutter situation before - Previously our bathroom was fully tiled and when updated (after the loft conversion) goimg back to plastered/painted walls on the external. Thus some of the thoughts about the mould. I'd even gone and looked out the neighbours dormer windows to see if I could see what was causing the overflow issues from another angle!

The conversion was performed by a company that had done a few doors down previously and in all honesty I don't recall ever having a conversation with anyone ever about it apart form they had to move our sky dish at one point.

Best have words with your neighbour then, as soon as possible, and explain you are firmly of the belief that their arrangement is causing water ingress into your home, and can they please deal with it.

We've had constant problems with next door, and out shared front and back gutters/fall pipes. Last year I had some damaged tiles replaced, followed by the gutters on my side given another good clean out. Next door, has never bothered, and this year had their chimney removed, resulting in lots more debris in their gutter, which then blocked the hopper, on our side of the boundary, causing our gutter to overflow down our wall, at the rear. I had words, they got their gutter cleared, but not the blocked hopper by their debris, so I had further words, pointing out that I wasn't about to pay a second time, for the hopper clearing, when their debris had blocked it. They conceded, and got their gutter clearing guy back to complete the job.
