Weathered Roofing Sheets
Asbestos Roof Removal Bundaberg | It has been widely known that in the past, asbestos-containing materials (ACMs) were used extensively as house materials in the construction industry. One of the most commonly used house materials containing a dangerous fibre is asbestos cement (AC) sheeting.
What is AC Sheeting?
Houses built before the 1990s are likely to use an AC corrugated sheeting in them. For your information, the AC sheeting does not contain a high level of asbestos. AC sheeting is a mix between cement and a small portion, usually 10-15%, of ACMs. AC corrugated sheeting is one of the products of bonded ACMs. AC sheeting or asbestos cement is also known as “fibro”.
Characteristics of Bonded Products
The characteristics of a bonded product are non-friable, rigid, solid, 7 mm thick and grey in colour. It also cannot be crushed or pulverised or reduced to dust particles. The ACM fibres are solidly bound in the product and are not released into the air. The product is also easily to be differentiated from other types of corrugated materials like galvanised metal roofing or ‘Colorbond’ steel roofing.
House Materials Containing Asbestos Cement
Besides for roofing, asbestos cement could also be used in other building materials, including:
- Exterior wall cladding
- Floor tiles backing material
- Insulation on hot water pipes and domestic heaters
- Water pipes
The non-friable product is less harmful compared to the friable product. However, DO remember that the non-friable material can transform into a friable one when it is disturbed, damaged or weathered. Once it gets weathered it may get brittle and change into friable. When it gets brittle, it can break and release fibres into the air. That is when the product causes some risks for our health.
What you need to know is that the fibre is very tiny and even thinner than our hair. The fibre can get into the lungs and causes severe health risks. People who are in danger of being exposed to the fibre are those who do the installation, renovation, asbestos removal or demolitions of buildings or homes.
Does Your House Use Asbestos Roofs?
To know whether or not your roofs contain ACMs is by identifying them through analysis in a lab. The inspection is an initial step before testing. You will need a licensed assessor to check the existence of fibrous products. To obtain a precise result, the sampling procedure should be undertaken by a NATA accredited lab. In case the asbestos testing is not conducted and there are some suspicions that the roofing sheets might contain fibrous materials, then you should treat the object as asbestos and manage the objects appropriately.
The obvious method for analysing a sample is to look for a roof chunk, covered it by hands using disposal gloves, and then put the chunk into the bag. Don’t forget use double bags and label them. Afterwards, send the sample to a lab.
Another method for testing is by applying a piece of sticky tape to the roof surface. As you remove the tape, it may retain some samples of debris or fibres. Once you are finished taking the sample, fold the tape and put it into a sealed plastic bag. Don’t forget to label it as well.
The result of previous testing will be documented in a report called ACM register. The register will inform you about the location, the type as well as the procedure employed.
Do You Notice Any Change in Your Roofs?
Is there any change in the appearance? Do you see any sign of weathering and lichen? If you see any change in the roofing surface, then you need to be cautious. Raise your awareness concerning the fibre exposure risk. It could be the time for doing a roof removal.
Commonly, the age of houses with ACM roofing now is nearly 30 years old, at a minimum. The roofs have been gone through weathering by the sun, wind, rain, air pollution, hail, lichen/moss growth and salt (for those properties in the coastal area). What usually happens to asbestos roofs is a major deterioration caused by weathering that wears away the cement matrix from around the ACM fibres. They are more prone to release fibres because their binding starts to loosen and more possible to breaking off.
To help you estimate the condition of the roofing in your property, here is a scale developed by WA Health.
|Unsound||Badly damaged roofs due to fire or physical action causing the structure to become not weatherproof. As the consequence, the house is inhabitable.|
|Very poor||Plenty of cracks as well as holes; easily visible raised ACM fibres all over the surface; cement flaking on the surface and can be easily scratched; the appearance of “whiskers” on downward edges of sheets; vast signs of leakage of water under roofs; showing many features of the “poor” damage.|
|Poor||Some extensive cracks or small breakages; signs of weathering roughening the surface of the cement matrix and showing fibres; noticeable appearance of “Whiskers” on sheet downward edges; flaking on the previously applied paint; water leakage sign under roofs.|
|Reasonable||Small visible discolouration, damage or deterioration; some physical marks, scratches, several number of breakages on the panel edge; a slight sign of breakdown of the surface of AC cement through weathering; small appearance of “whiskers on sheets downward edges.|
Asbestos Roof Removal Bundaberg Tips
Remove or Repair or Encapsulate?
For handling asbestos roofs, there are several methods, such as roof removal or encapsulation. For removing the material, the work must be done by a license removalist. This action will involve demolition of the roofing products. However, before you do the project, you need to complete a control plan. The control plan is important for you and the workers. It will give some important information related to the objects removed, fibrous products quantity and the tools used.
For encapsulation, the work will involve covering the roofs by using a non-asbestos roofing material. This method should be avoided since it only postpones the needs of removing the asbestos roofs.
DIY Roof Removal: Yay or Nay?
If safety is your priority, DIY is a nay. Removing the roofs is not an easy task. The bulky size will cause some troubles during the removing process. Additionally, corrugated roofs do not support weight, so you might fall when you step on them. Instead of getting the roofs removed, you might end up causing more risks of exposure. If you plan a DIY, you are required to use safety kits during the work. Therefore, if you want a safe and clean removal, hiring a professional removalist is a “Yay”. They have followed some training for jobs like testing or removal.
