Do you know that power washing an asbestos roof is a health hazard? This mineral has been used in countless products, including building materials. In the 20th century, asbestos was ubiquitous and widespread, including roof shingles, siding, and pipes. Power washing your home’s asbestos roof may disturb the material, releasing fibers into the air. Because asbestos is so dangerous when disturbed, it is recommended that you leave it alone.
While it is impossible to completely eliminate asbestos, there are steps you can take to reduce the risk. First, avoid any activity that damages asbestos. Asbestos is very brittle, so it can be easily broken. For example, you should never pressure wash an asbestos roof. Likewise, you should avoid activities that involve cutting, grinding, sawing, and drilling. This material can be highly abrasive and a significant health risk.
Pressure washing a cement-asbestos roof will release fibres and particles into the air. Wetting the material before power washing will help control the release of asbestos fibres and particles. However, it can’t control the release of asbestos fibres or particles once they’ve landed on the ground. Asbestos cement roofing has not been sold in the majority of countries, but it is not impossible to remove it by hand.
Asbestos fibers are released when disturbed. Luckily, if asbestos is intact, it will not release fibers. The risks arise when it’s disturbed, damaged, or disturbed. Depending on how friable the material is, the potential for release of asbestos fibers depends on age, wear, and location. Avoiding these activities will reduce your chances of contracting an asbestos-related disease.
