Pipe On Roof Between Tiles

[bedofroses]

Hello, my next door neighbour has had their roof replaced and where the tiles don't meet my roof the contractor has laid a pipe between our properties, is this normal as I've never seen it before?

Is it an actual 'pipe' (where its cross-section is a closed oval or circle) or an 'open valley', such as those commonly used to join two sections of roof together that lie at different angles
(as here https://tinyurl.com/ybrtcv2g )
but which could equally well be used to join two co-planar roofs together?

Thanks for responding, it's definitely more of a pipe than a channel. I've contributed to the cost as a chimney has been removed so I'm just concerned that there is less protection than before, and its not very attractive. I'll add a picture for info.

Thanks for the photo. It might be slightly easier for others to view here:

It looks more like some form of 'spacer', rather than an actual 'pipe' (designed to carry rainwater), to me. Perhaps TheBuilder might come along to help us out shortly? In the meantime, I'll see if that nice Mr Google can help out.

Aha!

Mr Google has indeed got us part of the way towards an answer. Apparently it's a bonding gutter, like the one in this illustration:

Now all we need is TheBuilder (or someone else in the building or roofing trades) to tell us if the one in your picture has been installed correctly!

It's a bonding gutter .. when you have diffent tiles on adjoining roofs, there is no way to have them overlap.

Hello

Well done Chris. Yes it is a double sided soaker.
Perfectly waterproof.
They're not very pretty, I know, but often, it's the only way to join two roofs that have different type coverings.

Actually, in the pic, it looks as though the coverings are the same, so it could have been omitted if so.
I guess he was trying to separate your roof from his, in case of any future arguments.

It's not a pipe. Nothing flows down the hole.

Looks like a good job. Nothing to worry about.

Thanks all for putting my mind at rest
