Garage asbestos roof repair

[cw018666]

Folks

just after some pointers here. I have an existing 6x3 garage which is leaking under the creasing tile and also along the abutting wall (cement fillet)

The roof otherwise is in good condition and is stable

my plan is to

remove squirty foam
Replace with cement fillet
Renew cement fillet on the abutting wall
Brush off moss
Cover the entire roof including the cement fillets with something like a waterproof coating, ie blackjack or acrypol or something similar

does this sound like a half decent plan?

Is there anything that could be applied to the moss to make it come off easy? Whilst it’s not difficult to remove when dry I don’t want to agitate fibres

thanks

Fungicidal wash will kill off the spores making it easier to remove.
Acrypol, cromapol or similar would be your best bet.
Something with fibres in it.

It’s actually better to jet wash the roof as long as you spread your load. The blast will get rid of the moss and because it’s all Soaking wet you won’t get any azzy flying around in the air. Then on a nice dry day you can put your coat of acrypol on it.
