We were advised our soffit venting was incorrect to the roof venting. The soffit vents were 4″ x 16″ cut outs were 1.5″ x 14″ the number was 1.5 to the roof vents.
Soffit venting was increased to ratio of 2:1 and soffit vent size was increased to 8″ x 16″ with cut outs of 6″ x 14″.
We have several areas in the home that are cathedral and this would also include our attached insulated garage which has free access to the non cathedral areas of the home.
Is the current ratio ok or it is advised to block some of the intake from the soffits?
