Attic Ventilation in Austin metro

Balanced intake and exhaust, which decides how long the roof lasts.

Ventilation is the cheapest thing that makes a roof last, and Austin 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.
