Bonding gutter advice please

[Pkdotm75]

My sons terrace house has a chimney mid roof pitch. It has a bonding gutter between his and the neighbours house which runs from the ridge, abutting the chimney back. The chimney has a back gutter fitted but the bonding gutter continues below this. Am I missing something or is this a ridiculous design - assuming it's been like it some time as the house is victorian. Either way, water leaking into the converted loft during the recent rains. Any advice welcome? The picture shows the bonding gutter in relation to the back gutter.

Are the chimneys still in use by both parties?

 

[Pkdotm75]

As far as I know they're not. Why do you ask?

 

[robinbanks]

Deleting them may offer you the most reliable way out of this problem

So you've not offered a solution other than remove the chimneys and re-tile, channel the roof.....thanks for that!!!

That is a valid solution.

No need for a refund, rather you offered sensible advice

To be fair I'm an engineer and could've come up with that so called 'solution' on my own. However, as the house is >100 years old, I thought a knowledgeable roofer may offer a reasonable solution or explanation that doesn't involve a complete roof reconfiguration. Thanks anyway

If I had a gaping 12 inch hole bashed in my house that I had no use for, and that was actively presenting a technically challenging problem related to waterproofing, I think I'd spend a day removing the problem

Why keep a chimney you don't need?

Robin, are you OK? We don't have a 12 inch hole bashed in our house...and if it was as you said, how would we remove the chimney stack and re tile the roof in 1 day?
You're clearly not a tradesman of any repute, so please save your 3000 plus comments for less serious issues

 

[Pkdotm75]

That is a valid solution.

Are your 7000 plus comments all as helpful Alistair?

I've always felt that a horizontal gutter behind a chimney stack is a poor detail. If I was keeping the stack I'd do a small pitch with valley either side, ballache as it is.
If I had no need for the chimney, I'd remove it and tile over, even if it took a day. I'm not as fast as nosey but at least I'm far rougher

My OP suggested it was a ridiculous design!! A fix/solution might be a ballache, but stack removal and retile ain't a days job for anyone. Thanks for your input
