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?
