Asbestos in Home Siding

The History of Asbestos Use in Construction

Asbestos, a naturally occurring mineral, found its way into the construction industry in the early 1900s. An Austrian engineer discovered how to mix asbestos fibers with cement, creating a material that was highly resistant to fire and heat. This innovation was quickly embraced by the National Board of Fire Underwriters, who recommended it as a safer alternative to wood for siding and roofing. By the 1940s, asbestos cement siding had become a popular choice for many homebuilders in the United States, valued for its durability and ease of maintenance. However, the tide turned in the late 1960s and early 1970s when health risks associated with asbestos exposure came to light, leading to a decline in its use.

Common Types of Asbestos Siding

Asbestos siding was primarily manufactured in the form of shingles or sheets. These products were known for their long-lasting nature and ability to withstand harsh weather conditions. The most common types included:

Asbestos-cement shingles: These were often used to mimic the appearance of wood siding.
Corrugated asbestos sheets: Typically used for industrial buildings but occasionally found in residential settings.
Flat sheets: Used for both exterior and interior applications, offering a smooth finish.

Health Risks Associated with Asbestos

When asbestos-containing materials are intact and undisturbed, they pose minimal health risks. However, when these materials become damaged or begin to deteriorate, asbestos fibers can be released into the air. Inhalation of these fibers can lead to serious health issues, including:

Asbestosis: A chronic lung disease caused by inhaling asbestos fibers, leading to lung tissue scarring.
Mesothelioma: A rare and aggressive form of cancer that affects the lining of the lungs, heart, or abdomen.
Lung cancer: The risk of developing lung cancer is significantly increased when asbestos exposure is combined with smoking.

It’s crucial for homeowners to understand the potential dangers of asbestos siding, especially if their homes were built during the peak years of asbestos use. For homes built between the 1920s and 1970s, it’s advisable to consider professional inspection services to assess the condition of the siding and determine whether any action is necessary.
