This is a Lomanco BIB Whirlybird turbine roof ventilator in white with a 14 in. head, sold as one piece. The original Whirlybird design uses permanently lubricated ball bearings for maintenance-free operation and pairs with intake ventilation to reduce energy bills and winter ice buildup.
Key Features:
- Vari-pitch base: The exclusive vari-pitch base adjusts to a 12/12 roof pitch for use on many roof applications.
- Maintenance-free bearings: Permanently lubricated upper and lower ball bearings ensure long life with no maintenance.
- Wind tested: Whirlybird turbines are tested to withstand winds of 110 mph.
- Water-deflecting vanes: 21 airfoil curved vanes with rolled edges deflect water away from the roof.
- Rigid construction: Rigid spider-type construction is riveted at every connection for durability.
- Rust-free build: The turbine head features 100% rust-free all-aluminum construction.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
Whirlybird turbines are a proven, low-cost exhaust option for attics: choose the 14 in. head when you want more exhaust capacity than the 12 in. model, and match white, aluminum, or galvanized finishes to your roof. Mount the turbine near the ridge with a balanced amount of intake ventilation at the soffit so air flows continuously through the attic. The vari-pitch base simplifies siting on slopes up to 12/12, and the large flashing speeds up a watertight install.
Installing a turbine vent requires working on a roof: use proper fall protection and follow manufacturer instructions and local building codes.
