You may have seen commercials recently regarding legal settlements for those who were exposed to asbestos and suffered from a particular type of lung cancer called mesothelioma. Lawsuits regarding these injuries and fatalities began in the 1980s, and actions still continue because this type of cancer can take up to 50 years after exposure to develop. Most of the lawsuits had to do with people who worked with asbestos-containing materials. Asbestos by itself is not a threat; it is a naturally occurring substance. However, when it is in a state where fine fibers are released and can be inhaled (referred to as 'friable), a substantial threat to health exists.
Is There a Chance There Is Asbestos in Your Home's Exterior?If you have an older home (built prior to 1980), you should be aware that asbestos was used in quite a number of building materials. There are many products that can have asbestos in them. Interior products contain spray insulation, ceiling and floor tiles, and pipe coatings. But asbestos was also used to manufacture a number of exterior building materials. These materials include:
- roofing felt and underlayment (usage still permitted, despite most uses being outlawed)
- shingles and roof tiles
- roof coatings
- cement wallboard and siding
- some vapor barriers
- miscellaneous construction materials such as caulk, flashing, and adhesives
