Asbestos Alert: The Risk of a Weathered Corrugated Roof

Why is a badly weathered corrugated roof needs more attention?  If you see your roofing sheets are covered in moss, lichen and grass, you might need to raise your awareness because it may pose a severe health risk.

Asbestos cement (AC) corrugated sheeting is composed of a mixture or a small amount of asbestos-containing material (ACM) and cement. Its colour is grey, and it has a distinct fibrous look especially when it has been used as roofing. It is easy to tell a corrugated ACM roof from another form of corrugated products like galvanised metal roofing and ‘Colorbond’.

When a corrugated ACM roof is severely weathered or deteriorated, it may become brittle and disintegrated. Another worse case that may happen to AC roofing sheets is hailstorms. It poses a risk to roofing, especially to the old, deteriorated or badly weathered roofs.

The History of AC Corrugated Roofs

In Australia, the AC has been used massively as cladding and roofing materials. It was mostly installed to the structures constructed before the 1980s. However, buildings built between the mid-1980 until 1990 were also likely to be constructed with this fibrous material. For buildings built after 1990, they are unlikely to contain any fibrous product.

As the effect of its massive use in the past, the AC product can still be found today in roofing sheet, guttering, vinyl tiles, fencing, water drainage or flue pipes and the underlay to vinyl sheet floors. This product could be installed in commercial, public or even private buildings. Many incidents due to its presence in various buildings keep appearing in the headlines. Residential, school, even public infrastructures are contaminated by this hazardous material.

The product was finally put to an end in December 2003. The Australian government started to implement a full ban on this material including mining, manufacture, import, store, use, reuse or sale of ACM products. The ban apparently has not stopped the use and distribution of fibrous products. Recent incidents in one of the hospitals in Perth have confirmed its appearance in new buildings built after the 1990s. The report said that the illegal products were imported from China.

How to Identity AC Material?

If you are still unsure whether your roofing, ceiling or wall cladding contains asbestos, check it. Do an ACM testing. Testing is also conducted before a renovation or asbestos removal project. ACM inspection should be performed beforehand to collect samples. For a more accurate result of testing, hiring a licensed assessor is strongly recommended. The professional assessor is familiar in handling a safe sampling and testing process.

The sampling process is possible to cause airborne fibres if the process does not follow the correct procedures. The recommended laboratory for asbestos testing is a NATA accredited laboratory. The result of the test will be put into an asbestos register. The register should include:

  • Data about the identification of fibrous products in the building;
  • The risk posed by fibrous products;
  • The control measures employed to minimise or eliminate the risk of exposure.

What to Do with Cracked, Deteriorated or Weathered Roofs?

According to some studies, AC sheets are not a significant health risk if left undisturbed and when they are in good condition. When the fibres remain solidly fixed in a solid matrix, they will not become airborne. If the damage is only a minor hole or cracked, then a repair can be a solution to your problem. Sealing or coating is the suggested methods for minor damage.

Remember that during the cleaning of the sheeting you should not cause the surface to be damaged and releases fibres. Do not use a water pressure cleaner. Use a hose and brush off the moss gently.

It is important to know that the repaired sheets need to be monitored from time to time to see any reappearance of a more severe disturbance. You have to remember that repair is only a temporary solution. In the end, the sheets should be removed.

Removal should be applied to any roofing sheet that is in poor condition that may pose a danger of airborne fibres. The process will include a total removal of the roofing sheets. Thus, the work should be performed by a professional removalist who has obtained a license and followed a training or course.

DIY for Roofing Sheet

If you plan to do DIY for removing your roofs, make sure you follow the proper procedures to avoid yourself from getting injured or exposed to the fibres.

The steps include:

  • Cordon off or shield your front yard and put a sign stating that an ACM work is being performed.
  • Wear personal protective equipment (PPE) during the work
  • Wet the roofs by spraying water before starting the work. This is to prevent the fibres from getting airborne.
  • Remove the old sheets carefully and then slowly lower them to the ground. Do not drop the products because it will break them, which can make them release fibres.
  • Wrap the sheets in Builder plastics and tape up each pack after removing them.
  • Vacuum the ceilings to remove fibres from your ceiling cavity.
  • Clean your yard and remove all the ACM debris when the work is over.
  • Make sure that the disposal process is following the regulations and is transported to an approved waste facility.

Remember, DIY is only allowed for a non-friable product. The size of the material should not be more than 10m2. The permitted working hour is only an hour per seven consecutive days.
