It is not intended for recreational use and is typically chosen for its appearance or to help reduce the "urban heat island" effect and minimize stormwater run-off. ''Extensive vegetated roofs'' only require a shallow growing media depth, generally as little as :75 mm to 150 (depending on the region), and therefore add little weight to the roof structure below when compared to a standard ballasted PMR roof. |

+ | :Recommended plant types for ''extensive vegetated roofs'' need to be drought, wind and frost resistant, such as self-generating sedums, herbs, grasses and other ''vegetation'' that can withstand harsh growing conditions. | ||
+ | |||
+ | :The water stored in the ''growing media'' and drainage/retention layer is sufficient to sustain the drought resistant ''plants'' between periods of normal rainfall. Thinner assemblies and very lightweight ''growing media'' blends are available for Extensive Garden Roof<sup>®</sup> Assemblies. | ||

To request a written Variance to the published limitation, follow the requirements in [https://rpm.rcabc.org/index.php?title=VRA_Standard#1.1.3.6._Variances Article 1.1.3.6.]. | ||
