Bonding gutter advice please

[ree]

OP,
Well done for sticking up for yourself.

1. Stopping the Bonding gutter as in the above pic is a fairly common practice. No problem when well done.
2. No way do you remove the shared chimney stack - it would be expensive.
3. No way do you remove the shared stack - its not impossible that the redundant flues might become future active.
4. No way do you remove the shared stack if its in a conservation area.
5. No way do you remove the shared stack when chimney stacks are a heritage feature that buyers of old houses delight in - it could be a selling point.

6. You dont show the upper bonding gutter up to the ridge?
7. The back gutter has been wrongly built - search some of my recent posts ref back gutters.
8. The back gutter flashing, and the stepped flashing require removing & re-doing correctly.
9. All the pointing in the pic needs grinding out to a 25mm depth.
The flashing turn should be 20mm then wedge and point or seal the full 25mm depth.

No way any of the reasons stated above, would prevent the OP from removing a redundant and troublesome chimney.

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.

For starters the flashing looks poor. The back gutter for instance, could do with a taller upstand as the current one could become overwhelmed in a good storm. Who knows how far it travels back up the roof?

Yes, a chimney bisecting the join in the two roofs is unfortunate. I've seen them exiting a roof in the middle of a valley too. Getting rid of the chimney is not such a daft idea when you consider that having a new chimney flashing fabricated will cost a fair bit. Regardless, I'd be minded to remove a load of tiles above the back gutter and start my investigation there.
