Asbestos Siding Shingles – The Truth About Asbestos Shingles, asbestosdefinition.com | If you have an older home that has been recently renovated, and you are considering replacing the roof or heating ductwork with a new system, chances are that you will eventually want to replace your old asbestos siding shingles. But how do you know which are the safest choices for siding? Many of the same concerns that apply to installing new roofing will also apply to asbestos siding shingles.
Asbestos is a mineral that occurs naturally in soil and rocks. It was used to make roofing materials for many years. The most common form is chrysotile, which occurs naturally in France and Italy. The production of chrysotile in countries such as the United States ended in 1971.
Asbestos has been associated with several types of cancer. Exposure to asbestos fibers has been associated with mesothelioma, a type of cancer that affects the membranes of the lungs and is particularly common in asbestos workers. Asbestosis, a disease that causes scarring of the lungs, can also be caused by asbestos exposure.
Asbestos-containing siding is not entirely safe. It does not necessarily mean that if a shingle has asbestos in it that it has some harmful effect on the occupants of the home, but it does mean that the possibility exists that some kind of exposure may occur through the use of the shingle. Because asbestos-containing shingles are much more likely to be installed indoors than outdoors, it is imperative that individuals with respiratory problems to avoid direct contact with the material.
In addition to installing asbestos shingles made from chrysotile, homeowners should be aware of the dangers that can result from chipping. Unless the entire shingle is covered, chipped shingles pose a health risk. People who often remove and replace roofing should also be aware of the potential hazards ofchipping. Some of the potential effects are respiratory conditions and liver and kidney damage.
Homeowners who work in the area of the house where the roof is placed are at the greatest risk of getting an asbestos exposure. The areas around chimneys, hot water heaters, and other areas where the chimney itself is near the ground are potential areas of asbestos exposure. Persons who work in rooms where chimneys are located or who climb around the walls of the house should be especially aware of the dangers of asbestos. Anyone who works in a duct or ceiling room in which a heater is located should also be aware of the potential dangers of asbestos exposure.
In addition to the dangers of direct exposure to asbestos, there are also potential dangers to the occupants of the home that are associated with living with asbestos. Asbestos-containing materials such as wall clings and upholstery are more likely to cause allergies than materials made of other materials. It is also possible that secondary skin reactions to the dust, or even serious medical problems, may occur if a person’s immune system is weakened by exposure to asbestos.
Before purchasing any type of siding products, it is important to make sure that the materials that will be used in the installation of the materials used in the siding have been evaluated for their potential to contain asbestos. Although many of the asbestos-containing materials that are used for siding may be considered “asbestos-free,” there are still a few that may not be. It is a good idea to make sure that there are no potential health problems associated with the materials that are going to be used in the installation of the siding.
After a homeowner has decided on which materials he or she will use for the installation of the siding, the next step will be determining what type of asbestos-free materials will be used for the replacement of the existing siding. There are two basic types of asbestos-free materials that can be used for siding replacement: manufactured or poured fiber cement and synthetic asphalt membrane. Although asbestos-free materials can also be used in the replacement of siding, the decision must be made between these two materials.
If a homeowner is installing the siding in an area that will have a higher concentration of asbestos, then synthetic asbestos membrane is considered a safer choice. However, synthetic siding can be more expensive than siding made from a natural material such as asbestos shingles.
When the cost of the siding materials is not as much of a concern, however, natural materials such as stone, clay and metal will be chosen over synthetic materials because they are easier to maintain. and usually last longer.
