How To Install A Whirlybird On A Metal Roof

Are you sick and tired of paying for exorbitant electricity bills each summer? For many Australian homeowners, they get hot under the collar both from the intensity of the regular summer heatwaves as well as the skyrocketing price of electricity.

Which is why it makes so much sense to install a whirlybird on your roof.

Using natural convection and wind forces, a whirlybird extracts heated air from the roof cavity of your home and replaces it with fresh cool air. This prevents the heat from radiating throughout the internal structures of your home and creating oven-like conditions in your property.

Would you like to discover the tips and tricks for easily installing a whirlybird on your metal roof? Come and learn the industry secrets from one of Australia’s leading whirlybird manufacturers.

Before We Start

Ok, before you get too excited, this is one important caveat: “Installing a whirlybird is best done by a trained professional, ensuring that a weatherproof seal is restored to the roof”.

Are you a trained professional? Can you safely access your roof? Do you have the necessary equipment to ensure proper waterproofing? If you do, read on, if not it might be the best option to bite the humble bullet and engage the services of a professional whirlybird installer.

If the waterproofing is not completed properly it can result in serious water damage throughout the roof cavity and internal structures of your home.

Step 1 – Identify The Ideal Location

Most homeowners prefer installing the whirlybird on the side of the roof that is out of sight. While whirlybirds are not an eye-sore, they do break up the lines of the roof, therefore keeping them out of sight can improve the overall aesthetic of your property.

If you are installing more than one whirlybird, you must install them an even distance along the roof to ensure maximum performance.

Step 2 – Mark The Position

On the bottom of the ridge cap, you will need to mark the position to identify the hole to be cut.

Step 3 – Cut The Hole

The hole needs to be cut carefully with an angle grinder or tin snips.

Step 4 – Install The Flashing Panel

Make sure the shortest side of the flashing panel is located closest to the ground. Fasten with screws and sealing washers.

Step 5 – Install The Pitch Collar

Once the flashing panel is securely installed, the variable pitch collar can be installed on top of the flashing panel. Adjust the angle of the collar so that it is horizontal. You can adjust the two halves of the whirlybird to change the vent angle. If the vent is not sitting flat it will not work efficiently.

Step 6 – Screw Into Place

Fix the collar into place using the supplied screws and tree metal straps. Make sure that the flashing panel is securely fixed on all edges. Silicone the inside seam of the collar and the screw joints to ensure a properly waterproofed seal.

Step 7 – Install The Rotor Head

Fix the rotor head onto place ensuring that the variable pitch collar is straight. Use the supplied screws, but do not over-tighten them, or it can cause the base ring to crack during intense storms. Make sure that the whirlybird is spinning freely and that there are no squeaks or strange noises.

NOTE: These instructions are based on the manufacturer installation instructions. We take no responsibility for installation work or damage caused.
