Water coming through wall

[m0t]

A few years ago I had external wall insulation put round my house and ever since then I've had water coming into my back room at one of the junctions between the main house and a single story side extension.

The water runs down the bit of the roof closest to the wall and overflows the end of the guttering and gets behind the wall insulation tracking through. I removed the guttering and used silicone sealant to round the inside of the cut out in the insulation that the guttering slots in to and this has reduced the water a lot but some still comes through.

It feels like the best plan would be to shorten the guttering so it doesn't sit inside the insulation and find a way to divert the water away from the wall. Any ideas or other solutions?

Get the installers back under warranty to do it properly

Would love to but they went bust quite shortly after it was done and the company providing the guarantee didn't last much longer than that.

Surely there was an insurance-backed warranty as part of either the b/regs application approved installer scheme or Eco grant?

Otherwise, you'll need to bodge something with some self-adhesive flashing or something like Acrypol liquid waterproofer.

Have you got a closer-up image of the wall/roof/gutter arrangement?

Should be lead work where extension roof meets house wall you don’t appear to have any ?

The work was done in early 2016 but we only recently noticed the problem because we redecorated that room (it wasn't showing through the many layers of gloss paint on top of wallpaper).

The firm that installed the insulation went out of business about 6 months later. The insurance company providing the guarantee went out of business in October 2016 and I received a letter from the administrator at the time saying that I wasn't entitled to any compensation and the cover had ended.

I'll try to get a better photo of the junction.

Looks like there is no flashing , just tile slips bedded against the wall..

This makes it more tricky . It maybe possible to slide a lead soaker under the tiles to steer the rain into the gutter ( said maybe)
Failing that you might need to get more destructive and pull off the lower slips and fabricate a flashing from under a tile higher up, dressed into the gutter.
Then bed the slips back

And make sure the stop end is leak free

I've got some more detailed photos.

I originally described this as an extension because it looks like one but actually the houses were all built like this so I can see several neighbours for reference.

The guttering seems too close to the bottom of the tile which is distorting it and the end and part of the reason the water is getting past. I think this is because the run to the downpipe is quite long so starts high to get the right fall and can see it is the same on both of my neighbours.

One of my neighbours has had flashing installed at this junction.

the gutter is at an angle, surely water will just flow out the inside edge in a heavy downpour?

its thoughtlessness or something that the insulation has boxed you in at the verge:

but for the time being, at the least, your gutter needs removing, cleaning - including breaking all seals and cleaning or replacing them.
and fixed back so its dropping - to even shallow falls but its got to drop.
re-arrange the down pipe if needed to give a fall to the gutter.
dont cut the gutter short.

Post pics showing more of the roof - some of the lower tiles are wasted and/or not nibbed on their laths.
and pics showing the down pipe end.

the verge tiles and fillet arrangement needs replacing with lead flashing with a Kick-out Gutter Divertor to lead the water into the gutter.

to drop the gutter on the fascia you would have to cut away at the insulation - big problem or installer's problem?

maybe the roof tile is reaching the end of its useful life - does it have underfelt?

if you paid by a credit card check out Section 75 Of the consumer credit act ??

You may be out of time but worth a look???

Bottom tile looks like it has slipped down an inch or so and is now deforming the guttering.

I managed to find a detail drawing of how this junction should look online.

They are supposed to have taken out the existing arrangement as filled the gap with a thinner insulation board and then installed flashing over the top.

What annoys me is that the council inspected it several times and didn't say anything.

take the gutter down and fit it properly , add a flashing as already mentioned

second tile back on first course looks damaged
