Asbestos Shingles
From the 1930s to the 1970s, asbestos shingles were used extensively
in buildings as well as in homes. Before it was banned for use in
construction materials, asbestos was a highly desirable mineral
because of its fire resistant properties and its strength and
durability. However, it was found that the very fiber that makes
asbestos such a valuable industrial raw material also makes it
dangerous to human health. There are literally hundreds of cases of
illnesses and deaths related to the inhalation of asbestos fibers at
the workplace or even at home.
What to Do
If you have asbestos shingles in your home, the first thing you need
to do is to determine its condition. Materials containing asbestos
are not per se hazardous to health. It is only when they are in bad
condition, in a state of disrepair, or disturbed that they become
potential hazards because there is a high risk of exposure to
asbestos fibers released in the air as a result of the removal or
disturbance.
What Not to Do
If, after assessment, the asbestos shingles are in good condition,
the best thing to do is to leave it alone. Under no circumstance
should the asbestos shingles in good condition be disturbed. Doing
so may cause the asbestos fibers to become airborne, thus exposing
you to its dangers.
If Asbestos Shingles are in Bad Condition
If asbestos shingles are in bad condition, you have two courses of
action. That is, you can either repair the asbestos shingles or
remove it entirely from your home.
When you want to repair asbestos shingles, it is best if you leave
this kind of work to licensed professionals. However, for
information’s sake, the process usually involves either of two
methods: sealing or covering the asbestos shingles.
Sealing will either bind the asbestos fibers together or coats the
entire material so that the fibers are not released. This type of
repair may also be used, not only on asbestos shingles, but also on
insulations for pipes, furnaces and boilers.
Another way to repair asbestos shingles is by placing something over
or around the material – in effect, covering the entire material to
prevent the fibers from becoming airborne.
The other course of action you may take is again best left to
licensed professional workers experienced in removing asbestos
shingles. They usually have all the necessary tools and protective
materials to minimize the risk of exposure.
Of the two courses of action, removal is the more expensive method.
In addition to being much more expensive, removal also poses the
greatest risk of exposure to asbestos fibers. So, unless it is
required by state or local regulations, this is usually reserved as
the last option.
