Stop work first. If you have found an old sheet that might be asbestos cement, the safest move is usually to leave it where it is, avoid breaking it up and work out what you are actually dealing with before you go any further.
Asbestos cement sheets are often found on garage roofs, sheds, outbuildings, fences and other older structures. They are not all in the same condition, and that matters. A sound sheet that is left alone presents a very different situation from one that is cracked, broken or already disturbed.
Quick checks to make before you touch it
Ask yourself a few simple questions before doing anything else:
- Is the sheet intact, or are there visible cracks, breaks or worn edges?
- Has it been drilled, cut, sawn or snapped in the past?
- Is it loose, weathered or shedding debris?
- Do you know for certain what the material is, or is it only a suspicion?
If you are unsure, do not guess from age or appearance alone. Older sheets may contain asbestos, but testing or sampling is the only sensible way to confirm it.

What not to do
Do not saw, drill, power-wash, snap or drag the sheet around to see what it is. Those actions can turn a simple identification problem into a waste and contamination problem.
It is also sensible not to sweep up dusty debris dry or mix the sheet in with general renovation waste. If the material has already been damaged, keep the area calm and avoid creating more breakage while you decide on the next step.

When testing makes sense
Testing is worth considering when the sheet is not clearly identified, especially if the material is mixed in with other debris, has an unusual finish or you are planning work that would disturb it anyway. A sample can help you decide whether to leave the sheet in place, arrange collection or plan removal.
That is often the clearest route for homeowners doing renovations, landlords planning maintenance and tradespeople who have found an unexpected sheet mid-job. It avoids unnecessary removal if the material is something else, and it helps you make the next decision with more confidence.
North East Asbestos Removal offers asbestos testing and sampling where that is the right next step.

If it is asbestos cement, decide whether it should stay or go
Not every asbestos cement sheet needs immediate removal. In some cases, if it is in reasonable condition and not likely to be disturbed, it may be left in place for the time being. In other cases, collection or removal is the more practical option, especially if the sheet is damaged, in the way of planned works or needs clearing from the site.
Where removal is appropriate, asbestos cement work may fall within non-licensed work, depending on the material and the task involved. That still needs care, planning and proper disposal. It does not mean it is a casual DIY job.

Keep disposal separate and lawful
If the sheet has already come down, the next priority is to keep it contained, undisturbed and separate from other waste. Do not put it in a skip with general rubble unless you have been specifically told that the waste arrangement is suitable for asbestos.
Professional asbestos collection and disposal is often the simplest way to close out the job properly, especially when the material is already removed or ready for uplift. North East Asbestos Removal can advise on collection and disposal for suitable asbestos waste and on appropriate non-licensed removal where that is the correct route.

If you have found an old asbestos cement sheet on site and are not sure what to do next, the safest approach is usually simple: avoid disturbing it, confirm what it is if needed, and then choose between leaving it in place, arranging collection or booking appropriate non-licensed removal.
