When is roof ventilation necessary, and how is it achieved?

Posted by admin
RunningBear asked:


How is it done? How does it fit in with modern airtightness standards?

Is it necessary even when there’s no airspace in the roof? (E.g. a cathedral ceiling, stuffed with insulation above.)

Thanks.
So… no attic, no ventilation required?
