The sheet was put in by roofer, looks like breathable membrane, there is black roofing felt. Will try and get some better lighting to take some more pics and will strip out tiles to take pics from outside. By the way do you know the right consistency for roofing mortar.

So forgot to post earlier but I removed about 6ft of the valley mortar, put new valley tiles in where there were ones that were cut to far back from where they should be and finally rebedded the tiles. The rafters in the loft are now dry and have stayed dry for over two weeks. So looks as if the leak was where the tiles had separated from the mortar and as the tiles did not go into the valley enough it allowed water to get behind the mortar.
