Asbestos tile is known for being susceptible to mechanical damage primarily due to its composition and brittleness. Asbestos products can crack or shatter when subjected to heavy impact or stress, making them particularly vulnerable to mechanical damage such as foot traffic, falling debris, or the impact of heavy maintenance equipment.

Additionally, asbestos tiles can become brittle over time, leading to a higher likelihood of damage compared to more robust materials. While other types of roofing materials like concrete, clay, and slate tiles have their own advantages and disadvantages, they generally have superior resilience against mechanical impacts, contributing to their widespread use in roofing applications.

Understanding the susceptibility of different roofing materials to mechanical damage is crucial for proper installation, maintenance, and selection based on the expected conditions they will face. This knowledge allows for better decision-making when assessing roof durability and longevity.
