I have a salt box roof on my garage and there are 2 sets/rows of windows in the long roof section one row exposed to the first floor and one row exposed to the second floor. My concern is in the rafter areas that are blocked off by headers for the window openings. The windows are 4 ft square so for every window there are 3 rafter bays between the bottom row and top row of windows that are essentially dead with regards to ventilation. Do you have any suggestions to venting these areas. Also below the bottom row and above the top row there are bays that are only open at one end.
