Sealing an old asbestos/fibro roof

Hello,
Just wondering if anyone can recommend a sealant for a leaky old asbestos roof....Preferably one that can be sprayed on.
Thx,
JB
 
Goody Goody a leaky old asbestos roof,my old friend :eek:

Has this roof got actually leaks like around the rubber screws or just broken areas???

Probably best if you can post a picture of the roof or the areas you believe it is leaking from or elaborate a little more on the problem:)
 
Nutech paints at Rydlemere across Parra river from Silverwater.
They specialise in roof paint for tiled roofs but also have a paint for asbestos.

But if it is leaking I think it will require more than just paint.
Is it fastened by the old screw and lead washer which may only require
re tightening.
 
the rule for removal ,
1, spray all panels with PVA glue.
2, whilst using resperator, remove the sheets without breakage.
3, Place them in 200au thickness plastic and seal with gaff tape.
4, get rid of the stuff for gods sake, this will avoid further issues from tennents,
 
Thx all...trying to get some pics soon.
How much to remove old/replace the roof (three bedroom cottage) with aluminium?

In it's current state (original and old) can these roofs cause health issues if left undisturbed?:confused:
Thx,
JB
 
No heath problems they know about,
They even say that drinking the water that runs off the roof without filtering cause no problems as the fibers go in our gut and not our lungs.:eek:

However the longer you leave it the the more expensive replacement will become.
I know for a fact that tradesman are willing "now" to negotiate more as work becomes scarcer.

I had a price a few months ago to remove and replace one on a 120m2 high set house and it was $10,000.

Low set should be a lot cheaper to do as safety barriers are probably not required.

Shop around,what it cost you now,you will get back two fold or more later in resale:eek:.
Also it could lose you a sale when you really need to sell;)
 
Here are the photos....

Thx painter,
I am only planning this one to be a keeper for about 5 years so I'm trying to minimise costs, but stop the leak. At least I think the attached photo is damage caused by a leak?? Any opinions....
Cheers,
JB

Yes, It is the old screw and washer type (see photos in previous post). Can they just be smothered in silicone? Would that work? Is there a kind of paint that is like spraying silicone on the roof?
I was only planning to keep this one for about 5 years....

These can be a pain to fix,however I would start with the washers by replacing them or undoing them and smearing silcone under, then retighten.
Look around carefully for any other areas to silicon.

Remember the water leak might not be above it,it could be over a metre away running to that spot when the height of water builds in the roof.

The one water damage near the manhole isn't that bad,however is is caused by water leakage from the roof.It could have been a one off storm that caused it by blowing under the recess.

The other spots looks like a spore,I would try and wash that off with chlorine or bleach.It doesn't really look like a water damage to me? More like a can of coke exploded.:p
Are there bubbles of paint under those spots?
Look in the roof above it and see what you see?



PS: Very good job vacuuming.
 
Some of those screws do look loose.
I have the same pitch and profile asbestos roof and same screws on a rental I'm doing up.
I did not have any leaks but still tightened the screws down, remember not
to over tighten or you could crack the sheets.
If you are unable to tighten put plenty of silicon on, roof and gutter silicon.
I don't see why you need to paint if you are only keeping it a few more years.
Go and buy a box of silicon.
 
The more I look at these pics, the more I think rain is blowing up under the sheets where the overlaps are not down tight. If this house has a precast ridge sheet, it's possible that the rafters have sagged a bit over time and opened a gap for rain to penetrate. I would silicon the overlap edges as well as any screws.

It would be interesting to know if the water damage at the manhole is directly below where it would leak from the ridge capping overlap.
 
I've been crawling around roof spaces for over 50 years, and I've never seen one in such clean and pristine condition.:)

I don't climb around roof spaces and thought how good the timber looked, and the roof condition generally, considering the age that it must be.

I'm no builder but it does look as if some new screws and a paint job should be all you need.
 
The other spots looks like a spore,I would try and wash that off with chlorine or bleach.

According to Shannon Lush of Spotless fame, chlorine merely whitens the spore. To kill it you should use a qtr teaspoon of oil of cloves in a litre of water. (My recollection)

I know her book is available from ABC book centers and would be helpful to many here.

Are you telling me that chlorine doesn't kill mould?
Looks like a lot of pool and spa owners are in trouble?
Its bleach that whitens:D
