I didn't have the heat stuff with mine- just bought some paint on tar type adhesive that was recommended to seal the edges.
The roof is approx 16 x 8 feet or so but like already said re the slope - it does have a very small slope on it so I suspect that helps. It had an asbestos roof on orignally that had gone porous - yuk!

I used this Ruberoid stuff http://www.ruberoid.co.uk/index.php?page=49 Cold Self Adhesive stuff.

Not much help if you gotta do it again though - sorry.

I did try some of that paint on stuff on the asbestos thats supposed to stop leaks but it didn't work for me no matter how thick I painted it on.

Tarpaulin til summer ?

Hello

phoenix n max, I have found the same problem with one panel of asbestos on my roof. (starting to go porous) will be getting some of the above recommended this weekend.

just out of intrest does the adhesive take to cold/damp asbestos?

Did you heat the felt or just paint it with tar?

regards

Topi - not sure if it would stick to damp wet asbestos to be honest. Maybe Bike Mad can answer that one ? Is it corrugated asbestos ? I found mine was porous in the channel.

No the stuff I used didn't need heating but then it was done in summer and it was warm I recall.

The felt I used comes as a 2 part system. One layer is black, sticky and you layer that one way as already said - then the top layer sticks to the top in the opposite direction with the seams away from the rainfall so to speak - does that make sense ?? - anyway I also purchased some adhesive that was supplemental but I do like a bit of overkill, just to be sure.

We removed the asbestos first though and replaced it with ext ply before putting the felt on. I guess you could try sticking the felt direct to the offending asbestos, with a bit of luck it may just work for a couple of months to see you though til spring ?

What Yeti is not saying, is how big his roof is:o If you have built it to the size you where talking. Its to big in my eye for a felt roof. You might have been better off with a pre coated corrugated steel sheet.

Have a look here http://www.slecladding.co.uk/plastisol.htm

It always was gonna be a bit iffy whether the felt was enough, but to be fair what is happening with the felt crinkling would have happened no matter what size. Ultimately I was gonna have a GRP coating applied, just looks like sooner rather than later.

^ job done - wish i'd seen that before.

Buy a pointy roof. :cool:

I had a flat roof over my garage bedroom that always gave problems so I had a hip roof fitted.........................now no problems at all, but it was expensive!
