I have a Panosonic fan and getting the roof re shingled. I want to exhast the fan out through the roof. Any recommendations for roof vents for it? I think it needs to be insulated right?
The ductwork to the roof vent should be insulated and should have a good damper. When I had mine done, I picked up the insulated duct and roof jack at Grainger, but I'm sure you can find them elsewhere.
The installation instructions should give you a good idea of what's needed. Hopefully, the roofers will install it properly!
