When are pavers most commonly used as walkway material?

Pavers are most commonly used as walkway material on ballasted single-ply roofs due to their functional design and benefits. In these applications, pavers provide a durable surface that can withstand foot traffic while also serving as a protective layer over the roofing membrane. The weight of the pavers helps to hold down the membrane, preventing wind uplift and ensuring the integrity of the roofing system.

In addition to their practical use, pavers come in various materials and designs, allowing for aesthetic considerations in rooftop spaces that may be utilized for leisure or communal activities. This combination of functionality and visual appeal makes them a popular choice for walkways in a ballasted single-ply roof setup.

When considering the other options, while pavers may be used in various roofing applications, the specific context of walkways on ballasted single-ply roofs highlights their distinctive advantage in enhancing both the usability and maintenance of the roof system.
