Best way to fix my roofing problem? (pics)

[BlackBarry]

I built an extension first (dark tiles) then my neighbour built his (terracotta). Because of the needs of his design & the lay of the land, we've ended with the edge of his roof just tucking under the edge of mine. Now the end-cap of my gutting can't fit and there's no room to manoeuvre the guttering upwards as it's already tight against my tiles. My neighbour suggests leaving the end cap off so water is discharged down his roof but I'm concerned about heavy storms when water could gush out and fall between the gap in our houses & cause problems. What's the best way to resolve this?

Surely his roof is still being tiled? What do the roofers think?

Can the roofer remove the tile that's pushing the guttering out and use lead in that area? I really wouldn't be happy with what they done so far in that area.

What exactly is it you're unhappy about wow ?

I hadn't considered leading the area. It wouldn't look very attractive. Yes the roof is still being tiled. I'm guessing it's the builders idea to just remove the guttering end-cap. I'm hoping to find a well thought through solution.

The designer has been incompetent by designing a standalone extension millimetres away from an obstruction. Either you or your neighbour is trespassing over the boundary there too.
But given the status quo the extensions should be flashed together so nothing can get between and the gutter should take account of that.
I'm not a roofer but I'm expecting to see an upstand party wall with both roofs flashed into it. But I'm sure there's a more cost effective option.
At least without the gutter end it'll be their roof that gets excessive water not yours, but I wouldn't be surprised if it then runs back off the side into your land.

Barry - it looks like a bodge. The guttering is twisted, it's not just the end cap. I've clearly annoyed you.

Has building control seen this?
What's the plan to surface the block work? How is water going to drain away from between the two walls?

That's awful!

Has your neighbour damaged your gutter?

Not at all Wow I'm just trying to learn, that's all. I want to find the best solution with the least hassle to both of us. I've no idea what building control think.

I've been up again and had a 2nd look. There is chasing for leadwork where the sides of the roofs meet.

The blockwork will be rendered.

I might be wrong but unless there is a gutter running vertical between the two roofs water is going to get in that tiny space?

I would not be happy with this extension at all and be checking in with planning to see if someone has cocked up somewhere.

This could be a big issue if you sell.

I wouldn't be happy if I was you or your neighbour tbh.

There definitely needs to be flashing between the two buildings, and if the only solution is to have your guttering go onto their roof then there needs to be something to prevent it flowing down their wall to the side (more their problem than yours.

If I were you I'd make the guttering slightly shorter to finish just before their roof starts, but it's not ideal (too late for ideal now, the roof is where it is).

My husband as a roofer totally agrees with Liara, they are both crap jobs, to my husband it looks like next door is using a builder to do the roof and not a proper roofer, dh says to request speaking with building inspector if your not happy.

Umm.

How the frigging frig is that block work going to get rendered?! It's impossible?!

As other posters have mentioned it is the possibility of run off from the roof making the wall wet that would worry me most. Even if the falls are good and the water is pushed away from the wall over time dirt and grot will build up and again could make the wall wet. It will never look very nice either. Was it not possible to either form a proper Valley or a box gutter? A box gutter may be formed by stripping the edge of both rooves forming the box gutter in.plastic or lead and overlapping the undershoot and tiles. I will caveat this by saying I'm not a roofer! Also I'd want to know if the local building control are signing this off and if not what the route is to achieve completion?
