Roof leak search

[Micramary]

Cannot find out why we have leak in bathroom. Mainly water marks, but now couple of fine cracks. Roofer been up twice, replaced soil vent pipe, taken tiles off, cleaned gulley - no marks on felt. Still getting water in somewhere. See photos in album. Any ideas would be so welcome. Photos show when raining for hour or so, the other after several hours.

don't know why this is upside down!

Long shot: upside down roof?

There has to be a broken/slipped tile or damaged leadwork somewhere.

Funny!!
The valley is not lead, is formed using small or cut tiles? So maybe this needs replacing with lead? The roofer could not find any broken tiles but maybe it is from further afield.

There has to be lead or a valley tray up there.

If you don't have any success locating the leak by sight then I suggest hosing the roof down, start at the bottom and work your way up after giving each area a good soaking and waiting to see when it leaks .

I would certainly be concentrating on broken tile, valley lead/ tray or lead collar.
