Leaking Porch advice

[rowlers]

1st post so I hope I'm in the right place!
So, I've got a 5 year old Barratt House and we have an ongoing leak from the porch that leaks into the downstairs loo. Barratt's have tried at least half a dozen times to cure it. The roof has been off, multiple new cavity trays, lead re-done....

I still have the 10year NHBC and Barratt's keep trying...

It leaks mostly when rain is driven by the wind.

this is the problem roof:

Wind generally blow in the direction of the photo.

This is the leak stain/s inside:

This is in the corner of the house as in the 1st pic.

I'm just looking for ideas that I can pass onto Barratts to give the something to think about..

Can any one give me any ideas?

Thanks

Cut a hole in the toilet ceiling and get a proper look in the void .

Where the lead flashing is cut at the verge and turned around the wall there should be a lead gusset welded in,
It may not be the solution but it is a possibility.

I agree the lead at top of verge could be dubious, it must be getting in on that dry verge somewhere. Can we have a PIC of the return lead up the top there. I can see all the fixing attempts they tried! Wow.

Thanks for all your replies.
Yeah, there have been many attempts!
The ceiling has been removed before, it can't have provided them any insight!

More pics, hope it is what you have asked for!

You can see that the side of the house get a lot of weather from the state of the sat dish!

Thanks again...
