During the installation of an asbestos roof encapsulation coating at a Moorebank Sydney facility with asbestos roofs, fitted with metal box gutters, testing picked up the presence of asbestos in the gutters.
This is a timely reminder to those conducting asbestos roof repairs, who work near or with materials containing asbestos to take care and follow the correct work procedures to protect your client, but just as importantly your employees.
Weathered asbestos roof sheets are in a constant state of degradation, due to the prolonged effects of weathering which breaks down the cement content of the roof sheets exposing the previously bonded asbestos fibres.

Currently there are only two ways to stop this breakdown process, one is to remove and replace the roof, the other is to treat the surface of the roof with an asbestos encapsulation coating.
Asbestos Roof Solutions Pty Ltd assess many aged asbestos roofs every year and are the number one roofing applicator for the Fibroseal asbestos roof encapsulation system in Australia. This asbestos roof encapsulation system was originally certified by the C.S.I.R.O. and has held the Australian Paint Approval Scheme (APAS Certificate 1720/2) for decades.
