The cowl that went on with the heater in a Hoppers Crossing home has had decades of weather, and plenty are rusting, loose or choked by now. FreshDuct replaces them with cowls matched to the flue, adds guards and spark arrestors, and photographs the result.
Cowl rattling on a Hoppers Crossing roof in the wind? Its fixings have rusted. A new cowl fixed properly ends the noise.
The cowl on top of a Hoppers Crossing flue is often the original from when the heater went in, and that can mean thirty years on the roof. Galvanised cowls of that age are rusting at the fixings and along the seams, the mesh guard is packed with old ash and leaves, and the whole thing has started to sit crooked. Some have already gone, leaving the flue open to rain and birds.
Replacing one is straightforward if it is done to the flue rather than off a shelf. We measure the flue diameter, check whether the top section under the old cowl is still sound, and fit a new cowl with corrosion-resistant fixings, a guard that keeps birds out without clogging, and a spark arrestor where the flue sits near trees or dry grass on the bigger blocks. Then we light a test and watch the draw with the new cowl on.
Gas fire terminals in Hoppers Crossing homes get a flue-side check for blockage and clearance; the terminal and appliance are the province of the licensed gas specialists we arrange, and a wood cowl is never put on a gas flue. Whatever goes on top, it is quoted firm once the flue is measured, fitted from the roof, and photographed in place, so you can see the new cowl sitting square without climbing up yourself.
Replacement cowls, bird guards and spark arrestors for the ageing heater flues of Hoppers Crossing, with the top section checked before the new cowl goes on.
A galvanised cowl that has sat on a Hoppers Crossing roof since the heater was fitted is rusting at the seams and fixings. We replace it with a new cowl matched to the flue and fixed with corrosion-resistant fasteners so it is not the next thing to fail.
There is no point fitting a new cowl to a top section that is rusting through. Before the cowl goes on we check the flue length under it, and if that section is thin we say so and quote it, so the new cowl sits on sound steel.
Hoppers Crossing's generous blocks give birds somewhere to nest and embers somewhere to land. A guard on the cowl keeps the flue clear, and a spark arrestor keeps embers in the flue where a heater sits close to trees or dry grass.
Real photos from Melbourne jobs — not stock, not staged.
The cowls that fail on Hoppers Crossing roofs mostly fail at the fixings. The replacement goes on with corrosion-resistant fasteners, is sized to the flue so it seats properly, and is tested with the heater lit so you can see it drawing.
If we are on the roof for a sweep, the cowl is checked and measured on the same visit and a replacement quoted on the spot. A photo of the finished cowl comes with the job.

Usually, yes. We check the top section it was fixed to, because a cowl that blew off often took rusted fixings with it and the steel underneath may be thin. If the section is sound, a new cowl matched to the flue goes on with corrosion-resistant fasteners; if not, we quote the section too.
If the flue terminates near trees, a timber fence or dry grass on a larger block, it is worth having. A spark arrestor is a fine guard built into the cowl that keeps embers inside the flue. We fit one as part of the new cowl and check it does not restrict the draw.
An open flue lets rain, leaves and birds straight in. A cap keeps the flue dry, keeps nests out and, on a wood heater, a spark arrestor stops embers leaving the flue.
Usually a downdraught — wind pushing back down the flue. An anti-downdraught cowl is the normal fix; we confirm the draw with a test before and after.
Yes. If we are on the roof for a sweep and the flue needs a cap, we can quote it on the spot and fit it the same visit where we have the right size.
