hail damage to your roof or any asbestos cement product can be as bad as waterblasting. Call a licensed asbestos removal contractor immediately if the hail was heavy. See Help and advice for contact numbers.
watch for weathering. Surface weathering releases asbestos fibres from roofs. Weathered asbestos products can be dangerous if airborne fibres are released when working, such as removing an asbestos roof or gutters.
what else is made of asbestos cement? Products made from asbestos cement not only include fibro sheeting (flat and corrugated), but items such as water, drainage and flue pipes, roofing shingles and guttering.
keep guttering (and downpipes) in good repair. As asbestos fibres collect in gutters after heavy rain, guttering and downpipes should be in good repair on buildings with asbestos roofing. Downpipes should not run into garden beds. Wet roof gutters before removing them and wrap carefully.
what about insulation? Insulation materials in house roof spaces are usually fibreglass, rockwool, paper or foam. Very few houses in NSW have loose asbestos insulation in the roof space.
is tank water safe? Tank water collected from asbestos cement roofing will contain some asbestos. Drinking this water does not present a significant health risk. You might consider however, replacing or coating your roof, or perhaps fitting a water filter to the kitchen tap.
