Asbestos could be lurking anywhere in your home, but two of the more common places is your roof and insulation. Asbestos fibers were used consistently in these two items for decades. These specific mineral fibers are dangerous once they begin to breakdown. This can happen for numerous reasons. Remodels, new construction, and even demolition can disrupt your asbestos-containing materials and cause you to become exposed.
Roofs take the brunt of the weather. Your roof essentially protects the interior of your home, so it is built to be tough and able to withstand sun, snow, rain, and hail. Asbestos fibers were a perfect addition to your roofing materials, as it is heat-resistant, very durable, and cost-effective. This made asbestos a miracle fiber to bind with other materials. Unfortunately, it became known in the 70s that asbestos fibers were actually very dangerous and caused illnesses like cancer and asbestosis. Since then, there have been regulations on all asbestos in the United States. It is still used in trace amounts, as it is still not fully illegal. Meaning you could have asbestos in your roofing, and you could become exposed.
Asbestos was originally used in insulation for homes and businesses. With asbestos being heat-resistant, it was perfect for insulation. Your insulation comes into contact with water heaters, heating ducts, and the exterior of your home. It needs to be heat-resistant and strong to withstand years or use. Insulation is not a material you often see if at all. It is hidden behind walls and ceilings. Unfortunately, you can still be exposed to asbestos in your insulation. Asbestos fibers are so small that they can travel through your HVAC to other areas of your home and expose you. This makes asbestos insulation very dangerous to your health.
The only way to know for sure if you have asbestos, is through a certified asbestos abatement professional. They will perform an asbestos test to see if you have asbestos on your property. If you do, they will help you develop a plan for asbestos removal. It is important that you remove all asbestos as soon as possible.
