Ballasted roofs are becoming increasingly popular as people strive to increase the usability of their building. For a ballasted roof system, Protan have developed Protan G Membrane which can be loose-laid onto the substrate or insulation on either a warm or inverted roof.

Two methods of ballasting are available:
- Gravel Ballasted Roofs - Gravel covering can be selected for a number of reasons - wind-loading, aesthetics and improved fire resistance whilst affording extra protection for the membrane.
- Recreational Paved Roofing - Paving stones are likely to be used for recreational purposes allowing the roof to be easily used by the building's occupants.
