What Is Asbestos Siding?

According to, asbestos is “a naturally occurring mineral composed of flexible fibers that are resistant to heat, electricity and corrosion.”

Asbestos is a group of six natural silicates that have thin microscopic fibers. Asbestos siding consists of these silicates and cement. Contractors used this material to insulate homes and increase fire and chemical resistance.

It is a strong, heat resistant material that was used by homeowners in many building construction materials such as insulation, vinyl floor tiles, asbestos shingles, and asbestos cement siding.

The Health Risks of Asbestos Siding

When materials containing asbestos are disturbed, asbestos fibers can be released into the air. This typically happens during removal and demolition work of the asbestos containing materials.

When the fibers are in the air they are easily inhaled by people in the area. According to the EPA (Environmental Protection Agency), this exposure to asbestos materials and fibers in the air increases your risk of developing lung disease. Asbestos exposure can be dangerous. Always talk to a health care professional about health risks and concerning symptoms.

What Does Asbestos Siding Look Like?

Asbestos siding was commonly used in homes built between 1920 and sometime in the 1960s. If you have a home or are looking at a home that was built during that time, especially if it his the original siding, it is a good idea to have it checked.

Asbestos siding comes in a wide range of shapes and profiles. It’s also available in many textures and sizes. Due to these aspects, there isn’t a particular appearance or style you should look for when you want to spot it.

How to Tell if Siding Is Asbestos

A combination of different factors can help determine if a siding contains asbestos. For instance, most siding panels with asbestos material have 2-3 holes at the bottom. Likewise, they feel denser than fiber cement siding when touched.

Other aspects that can help you identify asbestos siding are:

  • It has 12 by 24-inch shakes or shingles
  • It has a chalky texture
  • It may have a pressed wavy pattern or wood grain at the bottom

If you have the old packages, that is the best way to see if the siding contains asbestos. You can also call the manufacturer of the shingles if you are able to figure out where they were made.

Sometimes, it may be challenging to identify asbestos since some modern sidings mimic its appearance. In such a case, it’s best to consult top real estate agents. They can put you in touch with a certified asbestos inspector to take a sample of the material and submit it for analysis. With their help, you can confirm this information from construction or home maintenance records.

Contact an asbestos abatement company to help with handling asbestos containing siding and possibly replace them with asbestos free siding shingles. You want to be sure there are no asbestos particles released into the air when the siding material is removed, and professionals know how best to handle this.

Do I Need to Have it Removed?

Asbestos removal is something best handled by professionals. Check with your local building codes as they could be different per area.

If you need to repair before removal, you may incur an average of $4,761. When everything is said and done, the overall cost may be over $22,500 if you need several professionals.

What is Asbestos Abatement?

Asbestos Siding Replacement

Modern asbestos cement siding replacements are generally reinforce cement shingles with a variety of fibers. One of the most popular fiber replacements is fiberglass. Many of these new alternatives to asbestos siding perform in much the same way without the health risks.
