1908 house has an add-on bathroom with a ceiling light/fan/heater combo. In the attic the exhaust exited through the roof fine but he hose is plastic flex clothes dryer type. Considering this has a heater involved, is this something to write up? Or regardless?

Not a major problem but condensation within the pipe is the issue. If the pipe has low spots, or since it is ribbed, it can have the moisture in the air condense. The cold attic air condenses it quite rapidly and the pools of water can leak or grow mold. I recommend using smooth pipe and insulating ducts.
I seldom see it done but in a perfect world it should be insulated.
