    Fixed Price Whirlybird Installation

    We offer fixed prices on our whirlybird installation packages.  We reduce your lead time and cost by providing a fixed price install without a site visit.  On our first visit we will be prepared to do the job.  If what you ordered won’t work or isn’t fit for purpose, we will postpone the install. In its place we will provide a no obligation quote.

    – Stephen Covey

    When you dig down, our customers want us to deliver on a core set of values.  They want a product that is going to do the job they were expecting. They want it done for the price they were expecting. They don’t want anything to go wrong. They want it done by someone who knows what they are doing and is going to be around if something goes wrong in the future.  At Preferred Trades we have reverse engineered our service offering so we consistently deliver on these core set of values.

    The Number 1


    Firstly, we assess your roof’s size, layout and construction.  We then estimate the size of your roof cavity and determine its suitability for roof ventilation.  We leave nothing to chance.  We use aerial imaging software and real estate profiles to plan your installation, discover potential difficulties and determine which ventilation accessories will benefit your home.

    The Number 2


    Based on our assessment we get in contact to find out what is important to you about ventilating your roof.  Ventilation objectives can range anywhere from air quality improvement to cooling your home or even humidity removal.  Firstly we recommend a roof vent with enough capacity to ventilate your ceiling. Secondly we ask about features like thermostats (so they don’t run in winter or during the night) or ducting (allowing direct ventilation of your internal living spaces).  In the past it was common place for works to take place without ever discussing these requirements. This left customers with systems that looked the part, but didn’t live up to their full potential.

    The Number 3


    We design a roof ventilation package specifically tailored to your needs.  We then waste no time in putting our ladder on the truck and getting to your job.  We use a network of installers not only for quick turnaround times but also for reliability of service. Our installers follow our 5 Star Installation Process that is designed to deliver best results in three key areas – Property Protection, Safety and Workmanship.  Our 5 Star Installation Process has been developed over the lifetime of our business and is the direct result from installing thousands of roof vents.
