LiveRoof® Standard System (Conventional Roof)
by LiveRoof LLC

System/Material Acceptance and Product Details

The information published in the RCABC Roofing Practices Manual and offered below does NOT represent a complete set of the manufacturer’s data or specifications, nor is this system and its various materials recommended or endorsed by the Guarantor. The preparation of a detailed specification is the responsibility of the Design Authority.

Vegetated Roof System Manufacturer: LiveRoof LLC
Accepted for the RoofStar Guarantee Program: January 20, 2026
Accepted for application in: Vegetated Roof Systems
Acceptance Criteria: Refer to the RGC Standard for Vegetated Roofs
System Summary: The Standard System is the workhorse, used on 80% or more of LiveRoof projects. At 4.25 inches of soil, it is the popular choice for most new construction projects and many retrofits. With saturated weight of 27-29 lbs/sq ft, it is the perfect convergence of functional merits, cost and versatility.

LiveRoof's Standard System offers better storm water management over the LiveRoof Lite system and may also provide comparably higher energy savings — even more if irrigated during the warm season. This system is commonly used to meet green space requirements, provides modest biodiversity, supporting pollinators such as butterflies and honeybees, and will grow a palette of beautiful low maintenance plants—broad enough for both simple and relatively intricate designs. On top of this, the Standard System can seamlessly transition to the Deep and Maxx Systems without need for edging in between.

The type of plants used in the Standard System include a full array of low to tall growing sedums—from fine to very coarse-textured, green, yellow, blue, maroon and multi-colored. Flowers range from white, yellow, pink or purple. Alliums of all sizes are compatible and with regular irrigation a few a low-growing grasses such as little bluestem or prairie dropseed are possible, as are a few broad leaved non-succulent perennials.

^†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.
