Attic ventilation is the #1 driver of roof longevity in the Austin climate — and the #1 thing most homeowners get wrong. Here's the breakdown.
Attic ventilation is the #1 driver of roof longevity in the Austin climate — and the #1 thing most homeowners get wrong. Here's the breakdown.
Ridge Vents (Recommended)
Passive, continuous, no moving parts. Paired with soffit intake vents, they create natural convection that pulls heat out of the attic. Lasts the life of the roof.
Powered Attic Fans
Active, mechanical. Effective but draw conditioned air from the house into the attic if soffit ventilation is inadequate — actually increases cooling cost in many cases.
Texas Recommendation
Ridge vents paired with continuous soffit vents, sized to 1:300 of attic floor area. Powered fans only if structural design prevents adequate passive ventilation.
