working over an asbestos roof?

[7610]

If the shed was built after 1990 it is unlikely to be aspestos. That is not to say it isn't though. Sweeping it or spraying it is a problem if it is. I have two sheds built in 1990 that I thought were aspestos. The smallest is 4500 squ ft of roof. I had it tested for £20 and it proved negative. Look for marking on the boards if you want to identify it.

Little known fact, even modern roofing slates contain some asbestos, around 3% I think. The old corrugated sheeting is not going to cause harm every if broken. I was worried about this issue too at one time, phoned an asbestos removal crowd, they said just just rip the old slates off and bury them (Eire, like) told me they they set up air samplers on a factory roof

removal job for a demolition crowd, the guys were literally ripping and smashing the corrugated asbestos sheets off, obviously with hasmat suits and masks. Air samplers came back negative. In brief, only really an issue if you are cutting them with a grinder. That and asbestos insulation, that's the real bad one. Friend of mine's dad died of asbestos triggered lung cancer at 65-odd, from three weeks exposure thirty years before while he was working in an office and the load were redoing the insulation in the building.

I used to work removing asbestos so i know the type of asbestos used in roofing.As mentioned before dont drop anything on it as its quite brittle and could break.

As long as asbestos is left intact its perfectly safe,its only when its broken and the dust and fibres are airborn that its dangerous.

I wouldnt even bother with a facemask just leave well alone.If by chance some cuttings do fall onto the roof then id say take precautions with a face mask.

The chances of inhaling dust and fibres while out in the open air is miniscule anyway infact breathing in petrol fumes and wood dust all day is actually just as bad for your health

thanks folks, just wanted to be sure before taking it on, will make sure no cuttings land on it, and wear a mask as I have a decent one for when I'm cutting concrete.

Pretend it's a greenhouse - as mentioned it only gives off fibres when broken.

As an extra precaution if you wish; do the work in a wet day. Wet asbestos rarely releases fibres.

A customer of mine asked me to have a look at some conifers at the back of her house. some cowboy charged her £800 to lop the top two metres off a row of eight small trees that were only about five metres high to start with. He left the last three as they were behind the shed. I'm happy to finish the job but the shed has an asbestos roof. I wouldn't be standing on it anyway but was wondering if any precautions are needed?

 

 

If you need to ask the question, let someone else to do it!

i'm capable of topping a few conifers, just thought it was good practice to seek advice before working near dangerous substances etc.

It's not dangerous unless you plan to take a grinder to it.

A fairly sensible Question if you are not aware of how fragile Asbestos roofing is ,crack () on with job and has said treat it like a Greenhouse and all will be fine .

Big 6 asbestos is fairly ridged but only used mainly on commercial units etc so you will be dealing with the smaller ridges.
