A leeking Asbesdos Cement roof help...
It looks like I will have to move to a house with a rather naff single garage, the main problem is the roof leaks.. Also it has a dirt floor (some
cheap concrete slabs would fix this though), and no power (my current garage seems like a palace now!)
As we will only be in the house for a few years I can't justify spending a large amount of money on the house (it's a tide house so any
money spent will be lost)...
After reading:
asbestos
As the asbestos corrugated roof is 'hard encapsulated’ it seams I might be able to get away with brushing down the roof (to remove dust/moss
etc) and using one of those cheap an nasty felixable roof sealants?
What do you guys think?

I wouldn't brush it unless it has been raining to dampen down the dust. How about some clear plastic stuff as that lets the heat and light in
and doesn't cost much. Would be a good selling point in the future also.

I tried that, but the weight of the sealant eventually created more cracks. In the end it cost me less than 200 quid to have the roof replaced with
fibre-cement. Cheap when you consider the hassle if you did it yourself of transporting and disposing of the old asbestos.

You might seal the leaks initially but big problem is water is drawn into any cracks - first frost it forms ice, ice expands splits the sheet.

Interesting link, thanks. My workshop is made entirely of this stuff, and I did worry a little how risky it was to be in there surrounded by
asbestos!

The blue and pink stuff is considered to be safe if it isn't damaged and in good repair. The problem with a leaky asbestos roof is that the rain
will be carrying the stuff into the garage where it will dry out and become dust. That's bad!
I suggest painting the area with PVA to seal the dust and then a bitchumin based paint to stop the rain.
If it's a tied house, surely the owner is responsible for the health saefty and welfare of the occupants as well as the safe condition of the
structure?

Hi Chris,
Yep I think the only problem would be if you accidentally break the stuff. What I finds supprising is that you can still drill holes in the stuff with
out problems according to the link... Having said that I work in with research on aerosols (particulates in the air) its surprisingly hard to generate
an airborne aerosol from dust (brushing might do it mind)...
Any more ideas?
Cheers
Dan

Would tin sheets just go over the top to waterproof it?

Dan,
I run a demolition and asbestos removal company in Suffolk, so come across this issue all the time.
Do not dry brush the roof or get up on the roof without proper access boards etc. I have seen so many people go through brittle sheets.
What can be done is to apply a canvas encapsulation with a plasticised paint encapsulant (an ET150 or similar) to cover the asbestos cement material.
This has varying degrees of success. To be honest for the cost of doing that (or having it done) you would be as well to have it removed and disposed,
especially if the sheets are deteriorating.
