| |
| − | ;Accepted for the ''RoofStar Guarantee Program'': January 20, 2026

| |
| − | ;Acceptance Criteria: Refer to the [[VRA Standard | RGC Standard for Vegetated Roofs]]
| |
| − | ;System Summary: The '''Deep System''' by LiveRoof LLC is used for biodiverse green roofs. With 6 inch soil depth it becomes possible to support a broad array of non-succulent plants. One can literally create a prairie or shade garden on the roof. Naturally the weight is greater, appx. 40-50 pounds per square foot, depending upon soil and plants, but the weight is not so heavy as to greatly drive up the cost of the supporting structure.
| |
| − |
| |
| − | :LiveRoof's '''Deep System''' is primarily used for biodiversity, prairies, and garden-like perennial plantings. It also allows for food growing and shade planting, on roofs that are too shady for succulent plants. The '''Deep System''' is excellent for saving energy, good for storm water management, and easily meets most green space requirements.
| |
| − |
| |
| − | :The type of plants used in the '''Deep System''' include a full array of low to tall growing Sedums, hundreds of different fibrous rooted herbaceous perennials, including native forbs, sedges, grasses and edible plants. But, one should avoid plants with woody root systems such as shrubs, as they can damage waterproofing. Foliage colors can vary widely; green, yellow, red, purple and blue are possible, and flowers of any color and shape are found within the broad palette of plants capable of growing in its 6 inch soil profile.

| |
| − |
| |
| − | :While ''Semi-intensive'' and ''Intensive vegetated roof systems'' are limited to only ''protected membrane roofs'' (See the [https://rpm.rcabc.org/index.php?title=VRA_Standard#1.1.3.2._Permitted_Vegetated_Roof_Systems 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 [https://rpm.rcabc.org/index.php?title=VRA_Standard#1.1.3.6._Variances Article 1.1.3.6.].
