:<sup>*</sup> 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 [https://rpm.rcabc.org/index.php?title=Notes_to_VRA_Standard Notes to the Standard for Vegetated Roofs] for an expanded treatment on these types.
 
−
:<sup>†</sup> Saturated weight of a ''vegetated roof system'' depends on which components are used (since there are variabilities in many listed systems), but excludes the mature weight of ''vegetation'' as this is a variable the ''vegetated roof system manufacturer'' cannot control or predict.  It is therefore incumbent upon the Design Authority and structural engineer to factor these variables into load calculations.

:<sup>‡</sup> 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.

** Semi-intensive, Intensive, and Hybrid (blue-green) vegetated roof systems are only permitted on protected membrane roofs (PMR); see Sentence 1.1.3.2.(5) in the "RGC Standard for Vegetated Roofs". Any deviation to the "Standard for Vegetated Roofs" must be made by submitting a request to the RGC for a written Variance, as defined in Article 1.1.3.6.
† 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.
