I was wondering if I put a recirculating water pump to flow water over the
roof and outside vertical east and west sides if that would cool it very
much. I'm probably going to have to just try it. I get ag water, so
there's no problem about added cost.

Anyone ever done this?

Not that way but look into ag barn misters...
