What is the primary benefit of using a ballasted roofing system?

The primary benefit of using a ballasted roofing system is that it offers stability and reduces wind uplift. Ballasted roofing systems utilize weights, such as rocks or pavers, to secure the roofing membrane in place. This method creates a tight bond between the membrane and the substrate while effectively preventing wind from lifting or damaging the roofing material.

By leveraging the weight of the ballast, these systems provide a sturdy and reliable roofing option, especially in areas susceptible to high winds. This stability is particularly important since wind uplift can lead to severe damage to roofing systems if not managed properly. It is essential for roofing systems, especially on flat or low-slope roofs, to have a method to resist producing destructive uplift forces.

Other options, while they may have their merits, do not capture the key advantage offered by ballasted systems. Cost, ease of installation, and insulation properties are considerations for roofing systems, but they do not directly address the critical benefit of stability against wind forces, which is central to the effectiveness of ballasted roofing designs.
