- † Vegetated roof systems can be divided into three classic types: Extensive, Semi-intensive, and Intensive. Added to this are blue-green roofs, also referred to as "hybrid systems." Refer to the Notes to the Notes to the Standard for Vegetated Roofs for an expanded treatment on the three principal types.
- ‡ Minimum system and growing media depths may vary. For example, some manufacturers produce retention/detention mats in various thicknesses, to accommodate varying hydrological requirements. This may affect the minimum thickness of a system. Similarly, manufacturers may specify different minimum growing media depths depending on how the system will be used (i.e., deeper media if an intensive system is to be cultivated for rooftop agriculture). Always refer to the system page for more information.
