Percolation Tests questions, answered by experts

Vermiculite insulation that comes from a particular mine before 1990 is likely to contain asbestos. This is particularly true in the U.S. However, not all types of vermiculite insulation contain asbestos. Since you can't detect the presence of asbestos without special equipment, it's best to assume that the insulation contains the dangerous mineral and to either leave it alone or hire a professional to handle it.

Asbestos itself does not typically leak from a roof. However, if an asbestos-containing roof is damaged or deteriorated, it can release asbestos fibers into the air. This can occur when the roof is disturbed, such as during maintenance or repairs, or due to weathering over time. Exposure to airborne asbestos fibers can be harmful to health, so it is important to address any damaged asbestos roofs promptly and safely.

Asbestos-containing materials are not easily affected by water and do not disintegrate or dissolve when exposed to it. However, porous materials can deteriorate due to water exposure, leading to the release of asbestos fibers into the air. The settling of asbestos fibers can also occur as water makes them heavy, which reduces the risk of airborne exposure, though future disturbance of the materials could cause risk. Wetting asbestos-containing materials does not constitute safe removal, and the proper handling and disposal of asbestos materials should be left to professionals.

Federal law doesn’t require homeowners to disclose the presence of asbestos in their home, but some states and local municipalities may require it. That is why it’s important to test an older home for asbestos and other health hazards before moving forward with a sale.

The microscopic asbestos fibers do not cause eye irritation, throat irritation, or lung irritation. If you are inhaling fibers, you will not know it. This lack of immediate symptoms is one of the reasons why asbestos is so dangerous. You cannot know for certain if you are inhaling fibers, which is why you must wear safety gear if you could have any chance of an exposure while working.
