Do building codes factor in roof pitch?
A. Unfortunately, building code does not factor in roof pitch or cathedral ceilings. However, due to increased volume inside the attic as the roof pitch increases, Air Vent recommends increasing the amount of attic ventilation by 20% for roof pitches greater than 6/12; and increasing by 30% for roof pitches greater than 10/12.
