We have a roof deck on a Brooklyn brownstone building, built over iron joists of course, and are wondering if the deck could support a small portable plastic pool, about 8 ft long and 30 inches high.

Some have said water makes everything too heavy, others have said it's fine.

I would only trust the opinion of structural engineer that closely inspected the building. You say 8' long... if it is 4' wide x 8' long x 30" high just the water would be approximately 5136 lbs which would be much weight in a concentrated area for most structures.

You need to find out if your structure is engineered to hold that much weight in water.

I think it would cause other problems as well.

thanks! sounds like it probably won't work.
