By understanding the risks and implementing safe management practices, individuals can navigate the complexities surrounding asbestos shingles more effectively.

Understanding Asbestos Shingles

Asbestos shingles were commonly used in residential construction from the 1920s until the late 1970s. These shingles are made from a mixture of cement and asbestos fibers, providing durability and weather resistance. However, their safety has been a subject of concern due to the health risks associated with asbestos exposure.

Health Risks Associated with Asbestos Exposure

Exposure to asbestos can lead to several serious health conditions, including:

  • Asbestosis: A chronic lung disease caused by inhaling asbestos fibers.
  • Mesothelioma: A rare cancer that primarily affects the lining of the lungs and abdomen, strongly linked to asbestos exposure.
  • Lung Cancer: Increased risk for individuals exposed to asbestos, particularly smokers.
  • Other Cancers: Potential links to cancers of the larynx, ovaries, and other organs.

The risks are particularly high when asbestos-containing materials are disturbed, releasing fibers into the air. This can occur during renovations, repairs, or when shingles begin to deteriorate.

Hi, I’m Victor - the voice behind Element Roofing.

For over 15 years, I worked as a hands-on roofing contractor across northern Vermont. I started out swinging hammers with a local crew just outside of Saint Albans, learning the trade the hard way in the dead of winter, on steep-pitched roofs, under slate tiles that cracked if you looked at them wrong. Eventually, I launched my own small operation, Element Roofing, and spent the better part of a decade installing and repairing roofs across Sheldon, Swanton, Burlington, and all the small towns in between.

But people wanted to understand what was happening over their heads. They asked smart questions. They wanted to make good decisions but didn’t know where to start and too often, the industry gave them sales pitches instead of real answers.

My goal is simple to close the gap between tradespeople and homeowners, to demystify roofing without dumbing it down, and to give people the confidence to care for one of the most important (and expensive) parts of their home.

So feel free to dig in, explore, and take control of what’s over your head. We’re here to help from rafter to ridge.
