1.Scope 1.1 The purpose of this document is to provide guidance in the selection of a suitable roofing/waterproofing membrane within a vegetative roof system. The membrane may be the type that is UV stable or requires a protection layer from UV exposure. 1.2For the purpose of this guide, the structure and deck are assumed to be mechanically sound, provide slope to drain and is able to accept the weight of the vegetative roof system including the membrane, insulation, other roofing/waterproofing components including all components related to the vegetative layers as well as the required design loads. 1.3 Design criteria associated with the vegetative portions of the system are beyond the scope of this guide. Please refer to the Standard Guide for Vegetative (Green) Roofing Systems (WK 25385 Standard Guide for Vegetative (Green) Roof Systems 1.4This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the application of regulatory limitations prior to use
As Vegetative (Green) roof systems create unique situations, beyond what is typical for roof waterproofing. Selection criteria will be useful to designers of Vegetative (green) roof systems.
