OK, we're renovating the top floor in a duplex that's pretty old, maybe 50
or 60 years.
It has a flat roof.
Since the hosue was not insulated at all (between the old lathe and plaster

pouring though there, I would see some damage.
so if you can answer the question, I'd appreciate it, if you want to be a
smart ass, keep it to yourself.
