Asbestos in Roofing Materials?
Roofing Materials can contain asbestos. Many manufactures did use asbestos due to its ability to stiffen, increase durability, longevity, fireproofing etc. for Roofing materials. The following roofing materials are suspect for asbestos fibers and should be tested.
- Corrugated Asbestos Roofing
- Roof Flashing
- Vents
- Cement Roof Shingles
- Roof Sealants
- Caulking
- Mastic
- Felt Paper
- Underlayment
- Asphalt Roofing Shingles
- Roofing Tars and Liquids
Why Use Asbestos in Roofing Materials?
Asbestos is:
- Lightweight
- Chemically Non-Reactive
- Resistant to Heat
- Inexpensive
- Tensile Strength greater than Steel
Due to the exposure and protection that roofing provides for the structure it gets punished by sunlight, frost and moisture. Asbestos was used to prolong the life of roofing products. Due to its high resistance to degradation, Asbestos fibers hold and bind other materials together.
Asbestos has a higher tensile strength than steel making it ideal for helping strengthen roofing materials. Asbestos has extremely high fire and heat resistance. This makes it a perfect material to use for additional fire protection on a roof. The weight of Asbestos is very light in comparison to Asphalt, Tar and steel. Using Asbestos in roofing materials reduces the weight load on a roof making the construction much easier. Asbestos is an inexpensive material that was added in bulk to various materials by building product manufactures.Interpreting Water Test Results

Roofing Asbestos Testing FAQs
Roofing asbestos refers to asbestos materials used in roofing products such as shingles. Asbestos was commonly used due to its durability and fire-resistant properties. However, it is a concern because asbestos fibers can become airborne and inhaled, leading to serious health issues such as lung cancer, mesothelioma, and asbestosis.
There are many reasons that manufactures put asbestos in roofing materials:
- Lightweight – Roofs can carry only so much depending on how big they are. Lightweight asbestos roofing materials allowed for easy design for total roof loads.
- Non-Conductive – No need to worry in a lightning storm!
- Low Cost – Low cost of asbestos allowed materials to go further while adding strengthening properties.
- Strength Properties – Asbestos has a higher tensile strength than Iron.
- Durability – Asbestos is non reactive and inert for the most part making it the best for longevity.
Determining the presence of asbestos in roofing requires professional testing. Signs that may indicate asbestos include older roofing shingles and certain cement products. To confirm, it’s essential to hire certified asbestos inspectors who can safely collect samples for analysis.
Asbestos in roofing shingles is generally safe if it is in good condition and not disturbed. However, damaged or deteriorating asbestos shingles can release fibers into the air, posing health risks. Regular inspections and proper maintenance are crucial.
Minor repairs to an asbestos roof can sometimes be made without removal, provided the asbestos-containing materials are not disturbed. However, if the roof is significantly damaged or deteriorating, removal and replacement may be necessary. Consult with an asbestos professional for the best course of action.
Regular inspections are recommended for properties with asbestos roofing. An annual inspection can help identify any damage or deterioration early, allowing for timely intervention to prevent exposure to asbestos fibers.
