In which country is Coal Tar Pitch (CTP) not commonly used today?

Coal Tar Pitch (CTP) is recognized for its durability and resistance to moisture, making it a traditional choice in built-up roofing systems. However, its use has decreased significantly in various regions due to health and environmental concerns associated with the components found in coal tar.

In Canada, regulations around the use of harmful substances have led to a shift away from CTP. The country has implemented stricter guidelines regarding the use of materials that contain polycyclic aromatic hydrocarbons (PAHs), which are prevalent in coal tar products. This has pushed the roofing industry to favor alternatives that are safer and more environmentally friendly. Consequently, while other countries may still utilize coal tar pitch due to different regulatory environments, Canada has seen a decline in its usage, making it stand out compared to the other options presented.

In contrast, the United States, Mexico, and Australia still see varying levels of CTP use in roofing applications, influenced by individual market practices and regulations.
