roof vents placed behind 4ft walls in finished attic dont do squat for ventilation. no place for soffit vents, siding is asbestos so gable vents too pricey.
whats my best bet for adequate ventilation for finished attic room?

Hi William, 

Have you looked into ridge vent? Do you know how many LF your ridge is?

If the space behind the knee wall is clear from end to end and you install gable end vents at each end then that would keep the eaves from freezing and causing ice dams.Make sure the knee wall is well insulated. You want to keep the heat in the finished area and get the space behind the wall as cold as it is outside.What you need to do is create some convection in there. If you don't want to spend the money for this then you could try a high powered exhaust fan for one of the roof vents and try to get some air movement from that.

Hey William, 

I would say your best bet is to shingle over the vents and edge the vents at eaves. This way you are able to allow for intake and continuous ridge vent for exhaust. Hope this helps!
