It just occured to me that there were some flat roofs which were
effectively a tank that drained through one or more large downpipes. If
thats the case check for any blockage of the drains

Why people design buildings with flat roofs is beyond me. ...

....Also spent over a million re-doing the flat roof on the court house and
jail. Interesting that the jail roof still leaks in the same spots.

Anecdotal evidence from the apartment where I used to live:

After my complaining for three years about the leaks in the kitchen
ceiling, right on the two ceiling lamps, the owner gave up on going up
to the roof and trying to patch anywhere he thought might be the cause
and called the roofers. Some days after the new roof was in place we
had some snow and as soon as it warmed up water rushed down in the
wall space between the kitchen and the bathroom. Luckily for me this
time it went straight to the two apartments below, who were flooded,
and I only got to see it through a hole under the kitchen sink.

In short: Neither the owners, nor the roofers had thought on looking
at the rather old vent pipes, and one of the pipes was rusted through
which had been the cause of the leaks. All they would have needed to
do was break the wall of my bathroom and replace the pipe, instead of
paying 8.000 dollars can. for the roof. It was solved by
'temporarily' plugging the vent -it was never repaired, now the
building is being turned into luxury condominiums with the help of
some paint.
