At a glance

Common questions
How much attic ventilation do I need
The usual rule is one square foot of net free vent area for every 150 square feet of attic floor, halved when a vapor barrier is in place and intake and exhaust are balanced.
Can ventilation be fixed without a new roof
Soffit intake can be opened any time. Ridge exhaust is far cheaper while the roof is off.
