How to Remove a Roof Ventilation Turbine

Put your ladder on firm, level ground at a distance from the eave of the roof equal to one-quarter the height it must extend. For example, if the eave of your roof is 12 feet off of the ground, set the base of the ladder 3 feet away from the base of the house. Extend the ladder so that it extends at least 2 feet beyond the eave of your roof when resting on it. Secure all locks.

Climb carefully onto the roof. Have a partner hold the base of the ladder steady as you climb, if possible, to ensure your safety as you climb off of the ladder and onto the roof.

Lift the shingles covering the base of the roof ventilation turbine. Put a metal putty knife between the shingle's lip and the metal of the ventilation turbine's base. Push forward with short, firm strokes to break the seal between the shingles and the roof turbine. If you have trouble getting the metal putty knife under the shingle initially, break the seal on the lip of the shingle with a utility knife. If there are no shingles, move on to the next step.

Pull the nails out of the turbine's base with the nail puller on the back of your hammer.

Lift the roof ventilation turbine's base from the roof. Put the metal putty knife between the lip of the ventilation turbine's base and the roof. Push forward with short, firm strokes to break the seal between the base and the roof. Work carefully to avoid gouging the roof. Work all around the turbine until you are able to lift it free.
