Turbine Vent Installation

What This Service Involves

A turbine vent, sometimes called a whirlybird, uses even a light wind to spin its vanes and actively pull air out of the attic, moving more volume than a static vent of the same size. Our region's frequent marine breezes mean these vents keep turning and exhausting on days when passive airflow alone would stall. We choose sealed-bearing models that run quietly and resist the corrosion that our damp salt-influenced air can cause. Placement high on the roof and matched soffit intake are essential so the turbine draws from the whole attic rather than just spinning in place. Flashed and balanced correctly, it's an effective way to move moisture out cheaply.

Benefits

Actively exhausts more air than a static vent in any breeze; takes advantage of frequent Puget Sound wind; sealed bearings run quietly and resist corrosion; no electricity or wiring required; moves attic moisture out on mild, still-air days too

Our Process

1) Confirm soffit intake and select the turbine placement; 2) Cut the opening high on the roof plane; 3) Set the turbine level so it spins freely; 4) Flash, seal, and verify smooth rotation and draw

What Affects the Cost

Number of turbines needed for the attic; quality and bearing type of the unit; roof pitch and placement access; flashing and sealing per vent; intake corrections to balance the airflow

Best Time of Year

Installing in the drier months lets us flash the penetration cleanly before wet-season winds put the turbine to work.
