Asbestos cement profile roofing sheets contains only about 10 - 15% asbestos so is deemed a low risk material

Are my assumptions correct?

Hi Cliff, The corrugated roof is not harmful as long as its in good condition, any potential danger only occurs when the sheets have been broken, damaged or are deteriorating. Some people use an asbestos corrugate roof sealer to encapsulate the sheets, can be done professionally or by yourself if you know what you are doing.

Often found behind plasterboard too particularly around stairwells and lift shafts in non-domestic buildings from the mid 20th century. It can be easily missed on surveys.

Asbestos cement sheeting on garage roofs isn't a major problem if in good condition and left undisturbed. It's possible to remove it yourself under controlled conditions, and councils usually have provision to receive it (provided it's correctly wrapped) as waste at household waste recycling centres.

Asbestos found even on your ironing board.

We had a full survey done and they did not mention the ceiling in an outbuilding being asbestos.

I had a sample done and it is asbestos insulation board (chrysotile). It's around 7 m2 and we are looking at £2000 to £2300 to have it removed by a licensed contractor under controlled conditions.

I have just taped up the building and left it for now.

There is at least one commentator that claims white (chrysotile) is very low risk and can be removed by yourself. Others claim that such opinions are funded by asbestos exporting countries. The HSE is very clear that chrysotile is very dangerous in insulation board form as its dusts very easily. The WHO list it as a carcinogen.

I prefer to treat it with extreme care and am saving to get it removed professionally.

During my search for information I have come across conflicting information from test houses which I won't go in to here, I would just say that I think you need to choose carefully where you get advice from. I wonder how many true experts there are.

Asbestos Insulating board (AIB) generally contains between 25 - 40% asbestos, and not only comes as Chrysotile (white), but I have come across AIB being Amosite (brown) & Crocidolite (blue) mixed with chysotile or sometimes on their own.
there is no such thing as "Safer Asbestos" as Chrysotile is sometimes wrongly identified as.

There are two types of Asbestos, Amphiboles (Amosite & Crocidolite) - short straight fibres & Serpentine (Chrysotile) - curly fibres. These 3 are most common found in the UK, however there are 3 lesser known types (tremolite, Anthopyllite & Actinolite) - these 3 are also Amphiboles..
