Solar Panels on an Asbestos Roof in Geelong: Why Installers Say No and What to Do First
Solar quotes are routine across Geelong now. Where the process often stops is the site inspection on an older home in Corio, Norlane, Bell Park, Whittington or out on the Bellarine, when the installer looks up, recognises corrugated asbestos cement, and politely declines the job. If that has just happened to you, this guide explains why, what your realistic options are, and how to sequence the work so you end up with a sound roof and a working solar system rather than two half-finished projects.
Why the installer walked away
Fitting solar means drilling and screwing mounting rails through the roof sheeting into the battens and rafters, then having people walk across the roof for most of a day. On asbestos cement that is a problem on several fronts at once.
Drilling, cutting or screwing into asbestos cement releases fibres. The material is also brittle, particularly after forty or sixty years of Geelong weather, and it does not take point loads well. Installers walking on it risk going through a sheet, and the small feet of a rail bracket concentrate the weight of panels and wind load onto a surface that was never designed for it. Most accredited solar installers have a safety policy and insurance position that simply excludes working on asbestos roofs, and the good ones will tell you so on the phone before they even come out.
How to tell if your roof is asbestos cement
The classic Geelong asbestos roof is grey, corrugated sheeting with a wide, deep corrugation, usually called super six, often with moss or lichen in the valleys and a chalky, mottled surface where the cement has weathered back. Houses, garages, carports and sheds built before about 1990 are all candidates, and outbuildings are if anything more likely than the house. Age is the strongest indicator, but you cannot confirm it by looking. A single sample sent for NATA laboratory analysis settles the question for a modest cost, and our asbestos testing and identification service does exactly that, with plain advice on what the result means for the solar plan.
Your realistic options
Replacing the roof first is the option that solves the problem properly. The asbestos sheeting comes off under licence, the roof structure is checked, and a new Colorbond roof goes on. Colorbond is light, strong, straightforward for solar installers to mount to, and well suited to coastal Geelong conditions. The solar installer then has a clean, modern roof to work with and no reason to hesitate.
Mounting the panels somewhere else is sometimes workable. If you have a Colorbond garage or carport with a reasonable north-facing area, or room for a ground-mounted frame on a larger block, the panels can go there instead. The trade-off is that the asbestos roof is still there, still weathering, and still something you will have to deal with eventually, and the alternative structure may not have the orientation or area you want.
Sealing or painting the asbestos roof does not change the answer. Encapsulation can be a reasonable way to extend the life of sound sheeting, but it does not make the roof drillable or walkable for a solar crew, and installers will treat a painted asbestos roof exactly as they treat a bare one.
How the roof replacement runs
Removing an asbestos roof is licensed work in Victoria. The area is isolated, the sheets are wetted and lifted whole wherever possible rather than broken, and gutters and the roof space are cleaned of the fibre-laden debris that builds up under old sheeting over the decades. That clean-out is the step most often skipped by cheaper operators and it matters as much as the sheeting itself, because it is the dust that would otherwise sit above your ceiling for the life of the new roof.
The waste is double-wrapped, transported with the correct documentation and tipped only at an EPA-licensed landfill that is permitted to take asbestos, and you receive the paperwork. Our asbestos roof removal and Colorbond replacement service handles the removal and the new roof as one project, so the scaffold and access are set up once, the house is not left open, and the solar installer can be booked for a date shortly after the roofer finishes.
Check the meter board while you are at it
Many of the same Geelong homes have an old black meter board that may itself be asbestos, and a solar installation usually means the electrician will be working in that board, sometimes replacing it entirely. It is worth having the board assessed at the same time as the roof so that any removal is done once, by the right people, before the electrician arrives rather than after they have discovered it.
Sequencing the trades
The order that works is simple. Testing and assessment first, if there is any doubt. Licensed asbestos removal and disposal second, with the new Colorbond roof following straight on. Then the solar installer, and finally the electrician for the switchboard and grid connection. Give the solar company a realistic date for roof completion rather than booking them for the same week, because a small delay from weather on the roofing side is common and a missed solar booking can push you weeks down their schedule.
Getting started
Before you book, ask whether the removalist holds the appropriate licence for asbestos cement roofing, whether gutter and roof-space cleaning and disposal paperwork are included, and whether the new roof is quoted as part of the same job. If you have been told no by a solar installer because of your roof, or you suspect you will be, start with an assessment. We will confirm what the roof is, give you an indicative price for removal and Colorbond replacement up front, and work out the sequence with your solar company so the whole thing runs in the right order.
