If you still had it, you could cover the joint and always see the problem😁.

Hosed the wall on Max for 10 mins above that flashing overlap . The inside was slightly damp to touch from previous rain - so it makes judgement harder . But ! , 20 mins later nothing obvious inside ! . So will leave ( assuming it’s fixed ) as inside should be drier tomorrow and repeat . Looks promising though !

Ok . It still leaks - 1 drop and a bit damp .

I was hosing that area - I believe ( guess ) that spray from that maybe also hitting this overlap . So will ct1 that and repeat tomorrows test.

Ok , more than 1 drop . But not quarter of a bucket . So now to fix that 2nd overlap . There are no more overlaps on that run , so I hope this is it ….

So it’s something around this corner .

Took up the decking . Nothing obvious . Those overlapping flashings filled with ct1 look fine . Next test once it’s dried up and leaking stopped to flood this corner but not up or over the flashing - just the actual roof .

Not sure what else to try .

Took up more decking . Looks like the surface water does run round to that skylight . But it can’t be flooding around it . Also of course the leaks coming in under the roof not over the upstand . But it’s another possibility ( perhaps roof asphalt damage during installation of glazing ? ) .

Watched some flat roof leak finding videos . What I REALLY want is a method to make anywhere on the roof a water tight container around areas to isolate it .

For example if I took all the decking up around the skylight and put a 100% water holding barrier around it - that would be magic . But how ? . Can I use expanding foam on asphalt to build a retaining barrier ??? 🤔

How about putting a walk on, glazed roof over the whole lot?
