I am about to take a project on and wanted some advice.
I am going to vent my new bathroom fan through the roof. I saw the kit at Home Depot, some flex line, a fitting, the roof vent and 2 zip strips. This is unacceptable to me for a cold climate.
I want to use that 30 gauge circular ductwork straight up to the roof. Then from advice I read a while back, coat it in spray foam to prevent condensation.
Another question is if anyone offers a nicer bathroom fan roof vent. Anything I can find seems flimsy.
Thanks for any advice!
