Re: GBlist: Roof ventilation - soffit vents



While the general rule for roof venting is equal areas in & out, air is
pretty dumb and goes where it wants. You might what to have some pressure
measurements done to assure that the ridge vent is not pulling conditioned
from the house itself. You might find a local building performance
contractor from the web site listed below or email me if you have no luck.

Round vents are available from most insulation supply houses (J&R
800/343-4446, EFI 876-0660).

best,
