Vented roof with valleys
Imagine a ventilated cathedral ceiling roof with some valleys in climate zone 6B. It would have a vent channel in each rafter bay of a bit over 1”. In addition, it would have 2x4s as cross strapping on top of the rafters providing some cross ventilation below the sheathing. In this scenario, are the rafter bays in the valley areas (with no soffit vents due to the valleys) going to get adequate ventilation?
