System Summary
The Semi-Intensive Garden Roof® Assembly is considered a lightweight assembly, but with a slightly deeper soil depth, and is designed to support sod lawns as well as perennials. Lawns have unique needs due to the foot traffic they experience. Designers have the ability to create large lawn areas on rooftops using a Garden Roof Semi-Intensive® Assembly (See the link at right to the manufacturer's online resources page for more information)..

†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.
