Chrysotile roofing sheets should never be subject to loading.

The best solution is to re-roof it with onduline or twinwall etc.
- Buy some large bolt croppers
- Crop all the (usual) J-bolts from below
- Wear any N95 mask, wet the sheets above & below
- Slide the roofing sheets off, then prepare for disposal (*)
- Fit new roofing sheets

(*) Disposal is according to your council website:
Some have a pre-defined waste site, not the general site. You turn up
on a particular day with a piece, double bagged & taped. They then
approve its disposal, try to pick a piece with Chrysotile visible.

(*) Breakage should be painted with any scrap oil or latex paint:
Breaking a panel releases few fibres due to high cement content,
however care must be taken to not allow broken edges to act as a fire
against one another and likewise never drill, holesaw, saw or smash
panels. Painting any broken edges with any scrap oil or latex paint is
considered normal - many garage walls are adorned with scrap paint
from brush cleaning and sealing any broken side panels. Oil paint is
effective on cement, try removing oil paint from brickwork :-)


Cowboy asbestos disposal companies.
- Usually claim the asbestos sheet is something else
- Provide false material proof from pocket to you & insurers
- Make a pigs ear of it, cost insurers 12-20k, then sued
- The profit from many outweighs the litigation from some.

If the frame underneath is 40yr old rusty steel beware it will
collapse as much as the chrysotile break. Remove the side-panels by
angle-grinder on the *steel side* only after removing the roof sheets.
The reason is the side panels may actually be all that is holding it
up. Some people rebuild by bolting together 0.125" thick 1.5" L-angle
aluminium, somewhat like a garden centre or greenhouse. A considerable
amount of cross-bracing is required since modern cladding does not
contribute much rigidity to the structure unlike Chrysotile. There are
black recycled plastic agricultural panels available (Agriboard?)
which would make useful side cladding (infill panels) which are
relatively strong & cheap compared to alternatives.

What if you want to spread this out over a few years re cost/time/
hassle?
No problem, work from one end and progress accordingly - working from
below, never above (no need).

N95 mask, spray wet from above & below, crop the J bolts, simply lift
off the panels, old oil paint any suspect edges before removal if
bothered. Remember you have been walking around and inside the thing
for years, slamming the door :-)

Local garage, shares same type of roof as my workshop , had asbestos
roofing panels analysed for his employee insurance, verdict was it was
more cement than asbestos, removal not neccessay but when it may be
just advice to keep it wet, no requiremnt for specialist contractors,
having said that don`t think going to bother with moss on mine.

Contrast removal of asbestos pipe cladding at old hospital, totally
sealed , air lock entry, every6 section injected with resin, cut off
pipe, triple bagged , labeled and photo record of section of removal,
then taken somewher in sealed wagons.

I have pressure washed my roof. I've also gone at it (wet) with a
(hand) wire brush. This has been to clean the surface before repairing
a couple of spots of local damage. Pressure washing is a good way to
deal with this and leaves a clean surface for repairing afterwards.
However I've handled the run-off wastes carefully and then painted the
surface afterwards to seal it.

presumably some sort of analysis was required here? e.g. were they
perhaps moss "roots" you're remembering?

wiki advises:-
"industrially-processed chrysotile usually has shorter fibre bundles.
The diameter of the fibre bundles is 0.1–1 µm, and the individual
fibrils are even finer, 0.02–0.03 µm, each fibre bundle containing
tens or hundreds of fibrils.[3]"

that looks pretty small to me.....

8-) But washing it out, removing the organics and sticking the rest

We were somewhere around Barstow, on the edge of the desert, when the

saying something like:

Do not clean by dry scrapping or by pressure washing, both can produce
dangerous quantities of free asbestos fibres. Either:

* Use remote cleaning. This technique involves skilled operatives
using units with enclosed rotary cleaning heads and high-pressure water
jets, the filtering of the water run off and the disposal of the filter
waste as asbestos waste. It should only be carried out by skilled
specialist contractors.
* Cleaning with surface biocides. The biocides are applied with
low-pressure sprays or as washes. The roof is then left for the moss and
lichen to die, when it can be gently brushed from the roof with soft
brushes. It is important that the roof is kept wet during the brushing
and the waste is carefully collected placed in plastic bags and disposed
of as asbestos waste.

What a load of self-serving cock.

Leave the moss. Once you start taking it off, you release fibres which would
otherwise have stayed put. But if you really really must do this, make sure
everything is soaking wet before you start, and regularly spray as you work.

Some of us avoid swimming pools, and use a lifejacket when on water.

I've got fatter now, and I think I just about float in fresh water, but
I too used to be able to sink gently to the bottom and stay there. I
haven't tested for a while. BTW floating in salt water is easy.

The attitude of my teachers - who also claimed never to have come across
anyone who doesn't float - resulted in my gaining a mild phobia to water
that I've never quite got over, and that put me off learning to swim all
though my childhood. It was only when I wanted to learn to sail that I
learned to swim, in my mid teens.

When I was young I was over 6ft, and 10st 7lbs, which is thinner than
most - not much fat. We do exist.

Um...wasn't the fact that asbestos kept being sold so that Turner & Newall,
Cape Asbestos etc, could all keep making a quick buck. From what I now
understand, asbestos was being sold into so many different applications, and
it was downright unnecessary. And certainly not as beneficial as was made
out. It's fireproof, chemical proof 'magic' properties were not as unique as
the propaganda and advertising portrayed.

Now continuing to sell asbestos to developing countries whilst desperately
removing it from your own buildings (Quebec, Canada - selling to India) is
rather hypocritical, and again, making a fast buck!

Should have asked in the last post - can you provide that evidence please? I
would be interested to see it. Brown and blue asbestos were banned for UK
import in 1985 to my knowledge, with white being banned in 1999, under an
EU-wide directive. Labour had promised to do it upon election, but
apparently Canadian opposition and lawsuits were too much for any one
country to take on.

Undoubtedly discussing it does educate people. But still there will be those
who claim it's all overhyped.

I wonder if a lot of those people who really don't think there is an issue
would fancy sanding their asbestos roof, collecting the fibres up into a
bag, and then inhaling them. If they are so sure it's nonsense, then it
should be nothing to them.

What annoys me, is that the advice given a lot of the time is clearly
ridiculous (to dispose, smash it all up under a compactor and concrete over
it!!). There are cheap ways to do all of this - i.e. wetting the stuff - yet
still people have to know better, and just start scratching away at the
stuff. Now that's fine if you want to set up some great big sealed tent
around your garage, and get a lungful yourselves, but what about all of
those around you?

Anyway - nuff said. I know what I'd do if I wanted to get shot of some A.C.

not to ask what I've got squirrelled away inside them, but I can tell
you that I'm not worried about it catching alight...

that must be some microscope?!

so you've scraped multiple assorted large asbestos roofs using various
methods, been exposed to commercial quantities of doomed products -
and you're still here!!

who says we're being blase!

The issue is really down to what happens when the squirreled away stuff
catches fire and the roof scatters itself downwind due to steam
*exploding* the cement fibre.

Elfin safety field day!

Whenever the opportunity has arisen, I have replaced my big six roofing
with the post 1995 version or insulated steel sandwich.

Currently down to one small shed and the roof over a timber store.

For employers, the control of asbestos at work regulations 2002 imposes
a duty to manage the stuff in non domestic premises.

I have a plan:-)

Smokers don't ever think they will get lung cancer either, it doesn't mean
they don't.
Its a known risk that is easy to avoid, like looking before crossing the
road.

Not at all. It's like any of the similar minerals: the fact that the
smallest size for the fibres is getting too hard to see (and they're
the hazardous ones) doesn't mean that a typical sample isn't going to
contain a range of sizes, and there's plenty that's recognisably
distinctive well within the visible range.

Really though, the trick is just to wash the organics out with a bit
of chemistry and look at the minerals in isolation.

IMHO discussing it (from time to time..) is only going to have a
*positive* effect all around. What's the alternative? live by the
bible on a flat earth ??

Undoubtedly discussing it does educate people. But still there will be those
who claim it's all overhyped.

That because in the context of asbestos roofing it *is* overhyped.


I wonder if a lot of those people who really don't think there is an issue
would fancy sanding their asbestos roof, collecting the fibres up into a
bag, and then inhaling them. If they are so sure it's nonsense, then it
should be nothing to them.

Don't be so fecking stupid. Would you run out in front of the traffic
on a busy road, or would you take sensible precautions?

Absolutely. But I can't recall anyone mentioning getting a suitable
mask for use when scraping away at this stuff? Wouldn't that be a
sensible precaution? The way a lof of you discuss this, infers that
you can just scrape away at it, and let it disperse in the air. Yes,
my comment was stupid - but at least it provoked the 'precautions'
response.
