corrugated asbestos garage roof, how to spread my weight?

[RobertL]

I need to get up on the roof of my garage to remove the moss. I
don't have a feel for how much imposed weight I can put on a typical
asbestos garage roof before I crack the panels. The panels are
supported on wood beams about every 5 feet.

If I put up a couple of planks to spread my weight across two beams
would that be enough do you think?

I weigh 100kg clothed.

Get a platform (three-way convert-a-ladder - great things and well
worth Aldi's 60 quid) and stand alongside with a long rake.

No way will I use crawling boards on a small-corrugation asbestos
roof. The stuff is brittle as anything, and even if you don't go
through it, there's a risk of cracking it and resultant leaks.

[RobertL]

Thanks, it was cracking I was worried about. I hadn't even though
about falling through!

The corrugations are about 6" apart and about 2" deep.

No chance. Not only is asbestos cement weak and brittle, but there is
the danger from asbestos fibres when it breaks, as it surely will with
any weight on it.

Instead, use a ladder or staging to get into a position where you can
remove the moss with a pressure washer. Otherwise, don't bother.

If you insist on going ahead with your plank idea, you should call the
ambulance before starting work.

oh no! not the "asbestos cement DANGER DANGER" thread again I hope
Bruce?!

from wiki - to save the bandwidth:-

"Asbestos exposure becomes a health concern when high concentrations
of asbestos fibers are inhaled over a long time period.[23] People who
become ill from inhaling asbestos are often those who are exposed on a
day-to-day basis in a job where they worked directly with the
material. As a person's exposure to fibers increases, because of being
exposed to higher concentrations of fibers and/or by being exposed for
a longer time, then that person's risk of disease also increases.
Disease is very unlikely to result from a single, high-level exposure,
or from a short period of exposure to lower levels.[23] Smoking
combined with asbestos exposure may increase the health risk
dramatically"

Cant you just use a long stick to get the moss off?
Copper wire run along the ridge may stop it regrowing.

It depends on which fibres were used, which depends on when the roof
panels were made and by whom. In other words, it depends. And it is
extremely unlikely that any records are available, or remain.

My health and safety advisers take the view that *all* asbestos cement
products should be left alone or removed by a specialist contractor.

But I can understand people thinking that they can take a chance, and
that they will probably get away with it to save a few �s. The world

As above; very little danger if any, just because it is asbestos.
Cracking, leaks, falling through/injury yes.
Don't get onto it at all! Pressure wash or scrape from the sides, also
one could make a shaped scraper to fit the grooves on a longish
handle!
But why is it necessary to remove the moss?
PS. Have cut asbestos with hand saw, and on one or two occasions with
a hand held electric circular saw, during the last 55 years. Always
outside and making sure to keep everything damp to avoid inhaling
fibres. And am still around!

One of the worst things you can do with an asbestos roof is to
pressure wash it. Now that really does loosen the fibres up!

Personally I leave mine and its moss well alone. I fix it where it
needs it, otherwise we live in blissful mutual ignoring of each other.

I fell through one of my roofs last year - only about 6' down onto
piles of soft materials, but it could have been much worse. It cracks
without any warning at all. I was using a plank BTW.

If you are going to use planks, the plank needs to be strong enough to
support all of your weight without transferring any onto the roof
mid-span, it also needs to have the weight only supported over the
beams via spacers and the weight under the spacers needs to be put onto
the roof via some material with some give in it.

Squirt some good frame sealant into the inside (uphill) joint edges.
With a similar problem, that is what I did and it has proven to be very

Cleaning Asbestos Cement Roofs.

This should only be carried out if it can not be avoided, moss and
lichens although some may think them unsightly are not normally
detrimental. Asbestos cement is very fragile and so the recommendations
in HSG 33 Health and safety in roof work (1998) must be followed.

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.

[RobertL]

Thanks for all you guidance folks. Clearly I will need to do it
with a long handled something or other.

BTW, the reason it's needed is that it blocks the flow of water down
the roof so the water backs up and seems in through the overlaps. I
only need to clear the lower sections I think.

I did my large garage roof (approx 10m by 5m) in an afternoon using a
chimney sweep brush. Gaffer tape a weight to the brush end, then draw it
along the corrugations using the extender rods. Brush all the moss into
the gutter, then scoop it out with a trowel.

Hope this helps,

Roger.

How credible is that? The claim that moss from an asbestos cement
roof, which remains undamaged by moss growth, must be treated like
asbestos for disposal.

Not only that but they want asbestos disposal companies to do your

One car can kill you when crossing the road.

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.

Just try it. You know how effective a pressure washer is at disturbing
the surface of tired cement. Catch some of the run off water, filter
it off and look at the residue. Or else pressure wash a bit of it and
just look at the exposed fibres afterwards.

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.

[JimK]

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.....

What you forget is that some of us either have analytical chemical

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.

Whilst that is probably true, a blase attitude on these groups could lead

Asbestos (yes, even the white chrysotile) was banned for a reason.

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.

Unfortunately there is evidence that the reason _all_ types were banned
is so that someone could make a quick buck. White asbestos cement roofs
are more likely to cause a fall hazard than a cancer one.

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

EU-wide directive. Labour had promised to do it upon election, but
apparently Canadian opposition and lawsuits were too much for any one

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.

The issue is really down to what happens when the squirreled away stuff

Whenever the opportunity has arisen, I have replaced my big six roofing

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

For employers, the control of asbestos at work regulations 2002 imposes

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.

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

you can just scrape away at it, and let it disperse in the air. Yes,

I wouldn't do that with the dust from my vacuum, which is largely my

Well I'm going to assume that you aren't asking for evidence of the lack

So.. a link or two...

http://content.nejm.org/cgi/content/full/338/22/1565

That's interesting as a Canadian study specifically stating that the (US

Sorry - only just managed to plonk myself in front of the PC. Was finishing
part of the garage conversion yesterday - spraying the walls with a
fire-retardant mix of asbestos. ;-) Oh - OK - painting it with Dulux
emulsion! Anyway - thanks for these links.

Haven't read them properly yet - though a brief look at the first one shows
me two things that I immediately find questionable:

- the study was limited to women, to eliminate workers in the asbestos
industry
- [JW] so it would likely also eliminate anyone doing DIY asbestos removal
too? Surely factors like DIY working with the stuff should be taken into
account in any environmental assessment, as that's day-to-day usage?

- The results of this study are reassuring with respect to lung cancer, but
there were significant excess numbers of deaths due to pleural cancer (seven
deaths) and asbestosis (two deaths). The instances of pleural cancer suggest
an excess risk of mesothelioma. However, since historical death certificates
reflect the incidence of mesothelioma poorly we have launched a separate
study based on a province-wide survey of hospital records.

On the second article, much of the summarising at the end simply sounds like
the "yes, we as the asbestos industry know that blue asbestos is really bad,
and so by getting rid of that, we have cleaned up the industry".

I haven't scoured each article properly, as I said, and so I haven't found
evidence of "_all_ types were banned is so that someone could make a quick
buck".

I haven't found evidence of white asbestos being a significant risk
outside some production facilities - and even then it looks as though
contamination with other types may be involved. Certainly smoking is
strongly linked.

I guess it depends whether you want to be precautionary safe and ban
everything that isn't proved safe, or ban only things that are proved
dangerous.
