Ventilation is the cheapest thing that makes a roof last, and Philadelphia metro.
At a glance
- Intake at the soffit and exhaust at the ridge have to be balanced.
- Ridge vent with blocked soffits pulls air out of the house instead.
- Insulation pushed into the eaves is the most common blocked intake.
- A roof that ages early from underneath is usually an attic problem.

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.
