corrugated asbestos garage roof, how to spread my weight?

That's how we came down from the trees

That's just not true, you could get hit by a meteorite while you were climbing the ladder

Spent a year erecting pre-fab buildings

One on the roof drilling, one underneath putting on the clips. The air inside was a haze of fibres

RobertL explained on 03/03/2010 :

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.

PeterC was thinking very hard :

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 effective.

With respect - bollox!

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.

I'll leave my roof for 10 years. That way I'll be dead before meso has time to develop.

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.

Ah! You have 4" of extra storage space. My excuse has always been *very heavy bones* as I do not float. It makes swimming very hard work.

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 roof cleaning! I think we can see where that site's coming from.

bad idea.

WTF is "FIoR" anyone?

Fat floats, muscle doesn't, the bones don't appear to have much effect. I sink like a stone and can just sit on the bottom of the pool.

Good point - thanks.
