fixing a small leak where waste stack goes through flat roof

rizred · 22 Oct 2009

Hiya,

I have a small leak that seems to coming in where a waste pipe comes down through a felted flat roof.

It's a rented property so i wont be re-felting, but is there a product that i can paint on around the pipe to try and stop the leak? Is there anything that can be succesfully applied in these damp weather conditions?

Thanks in advance

There are lots on the market, basically you want the stuff with the fibres in that sends you high as a kite.

If there is a Screwfix near you then this is just the job.

Otherwise a local roofing merchants as long as its fibred usually called acrypol, sealapol etc

Even though these products can be applied in the wet, still try and do it on a dry day for that bit of extra stick!

Hi Rooofline,

I followed your recomendation and got a tin of Acrypol and used it last night,

It was as you described - nice and sticky and full of fibres - it filled around the waste stack really well and also covered all the old joins. It rained like a bugger just after i did it and i now have no leaks!!

Great recomendation, great advice and great product. Cheers!
