How do you keep insulation effective without choking off soffit airflow?
At the eaves, insulation needs to meet the roof edge without blocking the soffit ventilation path. How do you decide whether baffles that preserve an air channel are appropriate, versus treating the roof as an unvented assembly? I’d also like to know how the existing soffit and ridge ventilation affect that choice.
Before adding insulation, what signs would you look for to tell whether airflow is already blocked or the roof deck has a moisture problem? A cold-climate roof isn’t automatically suited to the same approach, so I’m curious what findings should guide the decision.

Soffit and ridge vents alone don’t show whether there’s a clear air path; check whether baffles keep a continuous channel from the eaves toward the ridge and look for visible obstruction. Staining or dampness on the roof deck can point to a moisture problem that needs to be understood before adding insulation. Both vented and unvented designs need a reliable air-control strategy. An unvented roof is an option only when the whole assembly is designed to manage interior moisture, not just because the ceiling plane can be made airtight.
