If your garage roof is old, cracked or starting to fail, asbestos may be one of the first things to consider before you plan a replacement. The important point is not to assume the roof definitely contains asbestos, and not to disturb it any more than necessary until you know what you are dealing with.
Asbestos cement roofing was commonly used on garages and outbuildings. In many cases, the material is in a relatively stable condition until it becomes damaged, drilled, broken or heavily weathered. That means the right next step depends on the roof’s condition, what you are planning to do, and whether you need a clearer answer before work starts.
First, pause the project and look at the roof condition
If you suspect the garage roof may contain asbestos, avoid sweeping, cutting, breaking or removing sheets yourself. Even if the roof is not visibly crumbling, unnecessary disturbance can create avoidable risk and complicate the rest of the job.
A sensible first check is whether the roof is:
- intact and still doing its job
- weathered, cracked or leaking
- already damaged by DIY work or a previous repair
- due to come off as part of a wider garage demolition or rebuild
The condition matters because asbestos risk is linked to disturbance as well as the type of material. A sound asbestos cement roof is different from one that has been broken up, drilled repeatedly or left badly deteriorated.
Do not guess from appearance alone
Age and appearance can be useful clues, but they are not proof. Many older garage roofs were made from asbestos cement sheets, but you cannot confirm that just by looking at the profile, colour or finish.
If you need certainty before you replace the roof, arranging asbestos testing and sampling is often the clearest way to decide what to do next. That is especially helpful if you are comparing repair, removal or complete garage demolition and want a more confident plan before work begins.
Testing can also be useful where a builder, roofer or landlord needs clarity before booking follow-on work, or where a property sale is moving forward and the roof material needs confirming.
Replacement is not always just a roofing job
If the roof is confirmed or strongly suspected to contain asbestos, replacing it is usually not a case of simply taking the old sheets off and putting new ones on. The project may involve careful removal, lawful waste handling and, in some cases, collection and disposal of material that has already been taken down.
North East Asbestos Removal provides practical help with asbestos garage roof removal, collection and disposal, and garage demolition where appropriate for non-licensed work. That can make the process more straightforward if you want the old roof cleared before the new work starts.

When removal may be the right next step
Removal is often considered when the roof is damaged, the garage is being demolished, or the material is in a condition where leaving it in place no longer makes sense. In those cases, the aim is to take it down carefully, keep disturbance to a minimum and dispose of the waste properly.
That said, not every asbestos-containing roof needs immediate action. If the roof is still intact and you are not disturbing it, it may be better to plan the work properly rather than rushing into a solution. The best choice depends on the job in front of you, not just the fact that asbestos may be present.
Non-licensed work still needs careful handling
Some asbestos cement roof work can fall within non-licensed asbestos work, but that does not mean it is simple or suitable for guesswork. Depending on the exact material, condition and task, some work may be notifiable non-licensed work, so it is sensible to get professional advice before starting.
It is also important not to confuse asbestos cement roofing with asbestos insulation or pipe lagging. Those are very different materials, and the legal requirements can be different too. If you are unsure what you have found, it is better to ask before any removal begins.
What happens if the roof has already been damaged or partly removed
If the roof has cracked, broken or been taken down already, the priority is to keep remaining pieces undisturbed and avoid creating more dust. Do not try to cut it into smaller sections or load loose sheets onto a vehicle without proper preparation.
If the material has already come down, the next step is often collection and disposal rather than further handling on site. You can read more about that here: What to Do With Asbestos Cement Waste You’ve Already Taken Down.
If you are storing the waste before collection, it should be kept secure, undisturbed and clearly separated from other materials. This helps reduce unnecessary handling and keeps the job organised for the next stage.
Planning a garage replacement or demolition
If your wider plan is to replace the roof as part of a garage demolition, it is worth checking the asbestos issue first rather than treating it as an afterthought. Once the roof type is known, the rest of the project can be planned around it more sensibly.
For homeowners and landlords, that usually means deciding whether the roof should be tested, removed, collected or dealt with as part of the demolition itself. Getting that sequence right can help avoid delays, surprise costs and unnecessary disruption.
If you are at the point where the roof needs to come off and you want a practical route forward, North East Asbestos Removal can advise on the next step, whether that is testing, removal, collection or disposal.
