Dangerous Signal on Houses Roofing
Before the mid-1980s, asbestos roofing, fencing, and guttering were popular building products among other asbestos-containing material (ACM) products. There were more than 3000 different ACM products, including gutters, roofs, fibro, flue pipes, gaskets, clutches and brakes. From all of the countries in the world, Australia was one of the highest users of this fibrous material till the mid-1980s.
The ACM was recognised for its unique quality. It is famous for its flexibility, known for its heat resistance, insulating properties and tensile strength as well as for fire proofing that insulate various properties; from houses to commercial constructions. The material was mixed with cement or woven into a fabric.
In contrast to its benefits, the fibre was proven to pose some health risks. When the fibre is inhaled, it can remains in lungs and generates a disease. To make things worse, the symptoms will not develop instantly, instead they will appear years later, up to 20 to 30 years from the initial exposure. Therefore, on December 31, 2003, having asbestos fully banned ended its’ use.
The full ban does not stop incidents related to fibrous materials because buildings constructed before the 1990s were still affected by their presence. In addition, some rogue contractors were found using illegal fibrous products supplied from China, as what happened at Perth Children’s Hospital.
Whether you hire or own a property, having awareness on ACMs installed in a building is important. Having the knowledge about the presence of any material containing dangerous fibres will minimise the risk of being exposed to the fibres.
Early detection is something each individual, who is responsible for managing and controlling a building, needs to do. Information related to the age of the building will determine the chance of a building being installed with a dangerous element. Older premises commonly contain ACMs.
Fibrous products are commonly made from asbestos cement (AC). The most common type of AC is asbestos sheet. AC products were used in commercial, industrial as well as residential applications and their typical use was for roofing or siding.
Type of asbestos sheets commonly found, including:
- Corrugated sheets
- Flat sheet
Houses with Corrugated Roofing Sheet
AC products were extensively used for housing since the mid-1940s till the end of 1980s. Therefore, residential buildings built before 1990 are likely to contain AC sheets, specifically in the eaves, ceiling, internal and external wall cladding and fences. AC sheets belong to non-friable type, which means it poses low risk and will not become airborne, easily. Yet, it can change into friable and releases fibrous particles when it is badly damaged or weathered.
The common use of ACMs in Australia is for roofing materials. The famous forms of ACM roofing were corrugated fibro, which was produced by Hardie Ltd.
Corrugated fibro was thicker compared to corrugated iron. However, it can get weathered gradually. A change in the material structure can be indicated by its appearance. As it gets exposed to the sun and rain for a very long time, the fibro product will start to deteriorate. If there is a natural disaster, such as cyclone, it will only add the damage to the house roofing.
If the ACM roof gets disintegrated due to the weathering away process, the products can turn into small particles. A strong wind can cause the fibrous particles to be airborne. It creates a higher risk for health because the particles contain high ACM concentration.
Identifying the Roof
Checking the age of the house can help you to identify the presence of materials containing hazardous fibres. To be completely sure, testing is the only available method. Asbestos fibre is very small and even thinner than human hairs; therefore, it cannot be visible to the eyes without the help of specialised apparatus. Fibres can only be observed under the microscope.
For testing, some consider DIY rather than hiring a professional assessor. DIY is permitted by the regulations. For DIY, you will need safety kits, including:
- disposable gloves
- disposable bags
- sample label
- duct tape
Note that during the sample collection process, you have to take precautions, such as:
- Clean the working place, tools, and equipment thoroughly when the jobs are finished.
- Clean all debris in the area, the tools and equipment by using wet mop and rags.
- Materials used at the time of inspection have to be placed into sealed bags.
- All the debris, offcuts and dust must be kept moist with water.
- Wear your mask until the job is completely finished.
- Don’t put ACM waste in a regular garbage bin.
- Remove and dispose of all safety kits properly.
- Clean your body; from head to toes.
However, to ensure a safe testing work, hiring an expert is strongly recommended since the substance is very hazardous. A single mistake during the sampling will cause fibre exposures.
Solution for ACM Roofs
- Encapsulation – For corroded roofing sheets, encapsulation is one of the methods that can be employed. Encapsulation can be applied if the material is in good condition. It is the fastest, easiest and cheapest solution for minor problems with roofing sheets. The method will provide protection and weatherproof properties to the damaged material. Make sure the encapsulation process does not disturb the fibre, such as using a high-pressure or rough brush for cleaning the damaged material. Safe handling is needed to avoid any disturbance that could release the fibres further.
- Over cladding – The method can be applied to ACM roofs that are badly deteriorated, weathered, or can cause a leak. The new roofing sheet will be installed to the old ones.
- Removal –The process involves the removal of old fibrous sheeting completely. Removing the roof will involve demolition, thus inspection and testing will be needed in advance. For roof removal, hiring a professional is strongly recommended
From all those three methods, the best option is still removing the roof because it will give a complete solution. It might cost more than encapsulation, but it will solve all the problems at once. Encapsulation is only a temporary solution because the coating might also needs renewal.
