Roofing

Is the mortar above the flashing likely to be the cause of my leak?

We have been having issues with leaks coming through our kitchen ceiling. The roof in question is an extension built probably about 15 years ago. It is a one story extension with the roof meeting the original exterior wall. It is not a flat roof. The leaks occur only during heavy prolonged rain and take a while to present and when they do its not a running leak but more like a drop every 20 seconds. All of which leads me to think the hole is likely to be quite small (relatively) I got a ladder up there and could not see any loose or missing tiles. No obvious holes. Only thing I noticed was the mortar being sparse or non existant around the flashing as per the pics in the link above. It would make sense this was the cause as its a straight run from there to where the water is leaking through the ceiling below. I am wondering if theres a way for me to confirm this is the issue or if i should just get the mortar corrected anyway. The only other way i can think of to confirm is to pull down the ceiling and see where the water is coming through (no loft type access currently exists). I would like to avoid that where possible particularly as removing and reinstating the ceiling is likely to cost more than repointing (if that is the fix ultimately) Thanks in advance for any help **looks like i cant include links so picture the flashing up against the wall above it is has a little lip so theres a small over hang between the wall and the flashing. The flashing is mortared in all along (poorly) then in the area of concern there is little to no mortar.**
