Does attic rafter vent size matter?
We are in NW Missouri between 5A and 5B. This is part of an addition with 24″ centers. The insulation company installed some rafter vents but not all. What they did install is smaller than the rafter span. I am putting rafter vents in the rafters that do not have any and air sealing the recommended areas. Should I replace the smaller rafter vents with bigger ones, too, or will it make a big difference? Thank you for the input. Pictures attached.
