Whirlybird installation is usually carried out by roofers as one of many roofing services they offer. Installing a whirlybird for the first time costs more than replacing an old whirlybird, as the roof will need to be inspected and eave vents may also need to be installed.
Whirlybird installation is available for residential and commercial buildings and all types of roofs, although some companies may only offer installation for tile roofs. Make sure you stipulate what type of roof you have in your ad.Roof inspection
An inspection is required to determine how many roof vents and whirlybirds you need, what size they should be and where they should be located for the most effective ventilation. This may be charged as an additional service or inclusive in the installation cost. An inspection can also catch any problems where roof repair may be needed.Whirlybird installation
Whirlybird ventilators are installed where they will have the greatest benefit for cooling your home and removing moisture from your roof space. Available in a range of sizes and colours to match different roofs, whirlybirds should be covered by warranty, usually for around 15 years. Whirlybirds are generally maintenance-free, but most installers offer repairs if something goes wrong.Eave vents installation
If you don't already have eave vents in your roof, these will help your whirlybird to be more efficient at drawing in cool air and preventing condensation. These vents are installed under the eaves of roofs to let air flow in and out, without letting in birds or pests. Like whirlybirds, they come in different sizes and colours to match different roofs.Solar whirlybird installation
More expensive than a wind-powered whirlybird, solar roof vent installation can offer faster cooling on hot summer days. These ventilators are powered by solar panels and may be recommended if you need more ventilation than whirlybirds alone can provide. Solar whirlybird installation is similar to a standard whirlybird, but more complex as solar panel installation is required.
