The Single Ply Roofing Industry [SPRI] and GRHC have published guidance on green roofs and fire. The guidelines cover a range of themes including Ballast, Border zone, Firestops,  Gravel stops, Growing media, Parapet and Vegetative roofing systems.

There is a review of various planting options for green roofs including both succulents and grasses.

The guideline makes ample use of the current German Guidelines for green roofs and is an excellent addition to green roof knowledge.

The guidelines can be download free of charge at SPRI
