Proper roof ventilation is about creating a complete airflow system.
In this attic, the lack of proper intake and exhaust ventilation contributed to significant deterioration, leaving the plywood rotting and splitting. The solution required fully re-sheeting the roof to give the new roofing system a solid foundation.
By addressing the ventilation and replacing the damaged plywood now, the goal is to prevent long-term problems and help the roof system perform the way it should.
Your roof is more than what you see from the outside. The health of your attic and roof deck matters, too.
