@alex @GrimCrack3rLiev followup query, where is the water coming from?

And where do you need it to go?

Does it tend to pool in one place or are there many small locatioms of puddling?

@GrimCrack3rLiev @jakimfett Yeah, unfortunately a new roof is way too expensive. I was thinking of creating a few tarps to funnel. We have a downspout on one side but we've had a new tarp tear multiple times in one month. :(

We have a big ladder and a cherry picker for mounting tarps, though.

@alex what is the intended purpose of the warehouse space?

Does the goal involve keeping some portions entirely dry, or is this about dealing with the standing water, or...?

Because using tarps and such as a stopgap until the rains are done sounds like an option, but if a little bit of wet is okay, focusing on fixing the drainage (and planning towards repairing things on the roof once the weather is more amenable to outside work) might be better.

There's also the question of where is the water going. If you have a storm drain or other dumping point for the water, fixing the drainage depends on what else you need the floor for too, because the straightforward method of cutting channels between standing water and the storm drain could make it less easy to walk or move things (especially heavy things) across.

Are there areas that don't leak that could be shored up around their edges with tarpage? It sounds like the weight of the water is tearing the tarps, and you might need a frame to encourage the water to run off the tarp (towards the storm drain?) but at that point you're kinda just building a small temporary inside roof.
