Asbestos Siding FAQ: Safety, Risks & Why Replacement Is the Best Solution
Is asbestos siding dangerous?
Asbestos siding is generally considered low risk if it remains intact and undisturbed. However, once it is cracked, drilled, cut, or deteriorating, it can release harmful asbestos fibers into the air.
Inhalation of these fibers is linked to serious health conditions, including:
- Lung disease
- Asbestosis
- Mesothelioma
This is why proper handling and removal is critical.
How can I tell if my home has asbestos siding?
Asbestos siding typically appears as:
- Rigid, brittle shingles or panels
- A cement-like texture
- Older installations (pre-1980s homes)
- Uniform rectangular or square shingles
The only way to confirm asbestos content is through professional testing.
What happens if asbestos siding is damaged?
Damaged asbestos siding increases the risk of fiber release. Cracks, chips, or deterioration can allow hazardous particles to become airborne—especially during repairs, renovations, or demolition.
This is why DIY repairs or removal are strongly discouraged.
Can asbestos siding be repaired?
Technically, minor repairs can be made if the material is intact, but this is rarely recommended. Any disturbance can release fibers, and repairs do not eliminate the long-term risks associated with aging asbestos materials.
Is it better to remove or cover asbestos siding?
In some cases, asbestos siding can be covered (encapsulated) with new siding. However, this approach has limitations:
- It does not eliminate the asbestos
- It can hide underlying damage
- It complicates future renovations or repairs
Full removal is often the best long-term solution—especially if the siding is deteriorating.
Why is professional removal important?
Asbestos removal must follow strict safety and environmental regulations. Licensed professionals use specialized equipment and containment procedures to safely remove and dispose of asbestos materials.
Improper removal can:
- Contaminate your home
- Put your family at risk
- Lead to legal and environmental issues
