Thanks. The felt is torn around the soil pipe in the attic. But if you are suggesting that it is running down between the tiles and the felt, then surely a) the ingress would have been visible in the attic; or b) say it was running down the side of the soil pipe and I didn't see it, then it...
A roofer from an NFRC registered company had a look yesterday, ladder was just left of the svp, took several tiles up. Couldn't find anything wrong, said it was dry underneath, no sagging, good overlap into gutter, and the ridge looked fine. Gave me his number in case problem reoccurs. Odd - but...
I suppose it makes a difference whether the underlay is overlapping the gutter. It looks like it is at the front:
Even in this case, I suppose if the gutter filled up then it would get behind the felt.
Although there are issues:
At the back, I can't see any overlap:
In places it looks like...
Thanks, they are operational but no they haven't been checked for partial blocking. The front gutter at least was overflowing during the downpour which was exceptionally heavy. Not sure what you mean by a fascia acting like a gutter. I have found stuff about the felt sagging behind the fascia...
Excellent principle, but what if one has a quote for three grand to replace the first metre of felt with breathable membrane (front and back of the house) from someone who hasn't even been up to look - when there seems to be a possibility that it might be enough to replace a tile?
Thanks again. Here's another photo taken from the other window, which I think shows that tile more clearly. Is it the thin lighter coloured tile to the left of the lead - that there may be a gap between that and the darker coloured piece of tile on its left?
Or 12 second video...
Thanks for your reply. Here's a photo:

Hi, there was a downpour last week and we had a substantial leak which appeared to be coming through the grouting of the tiling at the top of the window surround in the bathroom, and similarly through the top of the window surround in the toilet, which is next to the bathroom. On the 1st floor...
