Hi myoung,
Asbestos roof sheeting is the ‘sleeper’ in the asbestos debate. It suffers the most weathering and as such is most likely to be degraded to such an extent that the fibres are released into the atmosphere. The effects of the sun, rain, wind and hail lead to the breakdown of sealants and as such fibres can be released into the atmosphere, gutters and subsequently onto the ground in an ongoing manner.
Roof replacement is an expensive exercise as there are process that must be in place while sheeting is removed. Any material disposed off must be done so in an approved manner and discarding at tips can add other costs depending upon where you are.
Another technique sometimes used is ‘encapsulation’ – which is the application of a second, and approved, sealant that extends the life of the roof sheeting.
