Hi all,

In the last 6-9 months I have had a problem with leaking gutters in my semi detached home

I will see if i can get pics to help explain, the problem is at the corner of the back of the property.

I have a downpipe that is laid on to the roof of my extension. That pipe is pretty much serving all of the water from the side of the property gutter’s, the back of my gutters and indeed my neighbours gutters

When it rains really heavy, the water meets right on the corner of the gutters where the downpipe is, and instead of the water coming outta the pipe
It just gushes out of the gutter and splatters all over my extension roof

Got to a point where whatever I did nothing fixed it, so I paid someone to fix it. He’s been twice now but it is still leaking

Now being suggested that the neighours water should not be coming on my side
Good point, but im sure that water from the neighbour has been coming this side for years

Now it is being suggested to add an additional down pipe, right at the junction point between both properties

Do any of you have any further suggestions on this? Driving me nuts
 
yep sounds like its too much volume for a single dp.

look at your property and others on the street, see if theres any notable difference in their pipework?

Thanks

Just looked at that
And…

The setup i have is the same as other neighbours. I dont see one property with two downpipes but yes ofc i dont know if their gutters leak tho?

I noticed my joining neighbour also has a downpipe pretty much in the same place as mine.
 
I have a similar issue except the downpipe that dumps it over the extension has also fallen off lol. It's worked a real number on my pebble dash render.

From what I can tell, all the houses were built to share a single drainpipe. Then Joe Bloggs has had a nice kitchen extension built right upto the boundary, meaning the drain pipe can no longer be there. Dodgy builder comes up with an easy fix which is to dump the water onto the extension roof. This presumably is no where near enough surface area to get rid of two roofs worth of liquid.

I've just bought a ladder to reattach the down pipe that dumps on the roof, and I plan on aiming it as far over their roof as physically possible. I may even get a new section of down pipe to really make it a "done job". My entire patio is about 60% moss because of it.

Edit: sounds like you are "my neighbor" in my story above. You've built an extension that has meant removing the proper downpipe. Your builder has decided to dump it over the roof.
 
are you sure downpipe is not blocked ... often you have to disconnect the top section to access the leaf/debris filter (have a concrete tiled roof unfortunately that promotes moss)
 
Have you actually watched it when it's raining.
Is it just spilling over or going over with some force.
I wonder if the fall of your gutter is too great thus the water travels faster and is splashing over the edge.
It won't be nice but go up once it's raining and watch what is happening, you might need the downpipe just moving away from the end of the gutter so water doesn't gather at the end.
 
I will check if the pipe is blocked

The best way to describe the situation is that water basically drips from the soffit (old wooden one) but most of the water just gushes out from the side of the gutter adjacent to the side of the house with brutal force

Currently the placement of the downpipe/gutter looks on par with about 3/4 properties near me i looked at today

One question about the extension scenario
I wasnt happy with the builder when he dumped the downpipe on to the extension
What should be the solution?

Having an additinal downpipe will prob solve the situation but fear that water sitting on the roof isnt good for the long run and it will look unsightly
 
It's quite standard for one house of a pair of semi's to have the only downpipe from the gutter - some one has to have it due to the fall required in the gutter line. It was the same in my previous house. The one benefit is you get the possibility of connecting a water butt to collect the water, your neighbour doesn't.

It does sound like the downpipe is blocked or somewhat obstructed thereby reducing the flow and allowing the gutter to spill over at the lowest point. The blockage may not necessary actually be in the guttering, it could be somewhere in the drains to the sewer. If you've a soakaway rather than being connected to the sewer system then the soakaway could be blocked or saturated.
 
The lad I used to work for bought a buy to let and it was a semi -just the two houses -The front gutter went to next door corner and rear went to mates rear corner - Both houses were probably built in 80's - I had to go there one day as another neighbour had rung the letting agent about gutters overflowing and it was splashing on his propery.
Turns out both houses had serious moss problems on roof so gutters got blocked - unblocked them and it was ok till next moss blockage - My bungalow had moss so I used a roof moss killer on it and it's been fine ever since.
Now on your extension roof - what you can do is put a bend on end of downpipe and put a length on downpipe on it and it will take the water away and send it to any point on roof you want - somewhere close to the extension downpipe. - You could either clamp pipe to wall or like a mate of mine he used bricks to hold pipe in possition as it went diagonal across roof.
 
The issue can also be amplified if your neighbours downpipe is blocked. I noticed ours was taking a lot more water as it wasn't able to go down the neighbours downpipe and was coming our way instead.
 
It is like the water from alongside the back has too much water for the corner to deal with

may be it is just too fast
I don’t know he’s saying put another downpipe down but like i said
Unsightly.
