I have a warehouse with a flat roof. It has two drains and is supposed
to be inclined uniformly towards the drains. However, between the two
drains, a depressed area appeared and water pools there. From there,
it leaks down into the warehouse.

I am looking for cheap workarounds to stave off roof replacement. I am
wondering how hard is it to add a roof drain and connect it to
existing drains. Will that help?

Depending how long it's been leaking, could be very hard, as you might
open it up to add the drain and find that the thing is rotten from years
of leakage.

You could look into having someone build up the low spot with spray foam
roofing (or resurface the whole roof including building up the low spot,
depending how much $ you are blowing on heat out the roof.) If the
underside of the deck seems solid in the area, that might work well
enough for long enough. If it's clearly rotten all the way down, you
likely need to give up and have a real repair made before it gets worse.
