System Summary
The Extensive Garden Roof® Assembly is designed for locations that will receive little maintenance or where structural capabilities are a concern. 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 (See the link at right to the manufacturer's online resources page for more information)..

Conventionally Insulated Roof Assembly by roofing Contractor
†Guarantor's Notes
Systems labeled "Inverted" are designed for a protected membrane roof assembly, also known as an inverted roof assembly.
While Semi-intensive and Intensive vegetated roof systems are limited to only protected membrane roofs (See the Sentence 1.1.3.2.(5) in the "RGC Standard for Vegetated Roofs"), some vegetated roof system manufacturers offer their systems for conventionally insulated roofs. To request a written Variance to the published limitation, follow the requirements in Article 1.1.3.6..
*Conditions and Limitations
Note that system thickness is dependent upon the selection of components, which is determined (in part) by design parameters, including hydrological requirements. Consult with the vegetated roof system manufacturer for options and saturated system weight.
Also note that vegetation coverage under the RoofStar Vegetated Roof Guarantee applies only to extensive systems planted with mats or trays - see Part 3 of Division A for more about coverage.
