What is a critical factor to consider when designing high-traffic areas on a roof?

When designing high-traffic areas on a roof, selecting appropriate walkway materials is crucial. Walkway materials should provide sufficient durability and resistance to damage from foot traffic, as well as adverse weather conditions. This ensures that the roof's integrity is maintained over time, preventing wear and tear that could lead to leaks or structural issues.

Choosing the right materials, such as rubber, pavers, or specific high-performance membranes, allows for safe and efficient use of the space. These materials not only protect the underlying roofing system but also enhance user safety by providing adequate traction and reducing the risk of slipping. Therefore, the selection of walkway materials directly impacts the longevity and functionality of the roof in high-traffic areas.
