Green Roof Media

Green roofs are typically classified as extensive, semi-intensive, or intensive depending on system depth, plant selection, maintenance requirements, and intended function. Proper green roof growing media is critical to long-term performance, drainage, plant health, and structural loading.

At Premium Soils, we supply engineered green roof growing media designed to meet the unique requirements of commercial, municipal, and residential green roof applications throughout British Columbia.

When designing a green roof system, factors such as saturated bulk density, water holding capacity, permeability rates, drainage performance, and soil structure all play an important role. Our team can provide custom green roof soil blends tailored to your project specifications, whether for small rooftop gardens or large-scale urban developments.

Extensive Green Roof Systems

Extensive green roofs are lightweight, low-maintenance systems typically designed for shallow growing depths and drought-tolerant plant species. These systems generally require little to no irrigation and are commonly used for sedum roofs, environmental offsets, and large rooftop coverage areas.

Semi-Intensive Green Roof Systems

Semi-intensive green roofs offer a balance between lightweight extensive systems and larger intensive rooftop landscapes. These systems can support a wider variety of vegetation, including grasses, shrubs, and small feature plantings, while requiring moderate maintenance and irrigation.

Intensive Green Roof Systems

Intensive green roofs are deeper, heavier rooftop landscape systems capable of supporting trees, shrubs, pathways, and public access spaces. These systems often incorporate irrigation, drainage layers, root barriers, and engineered structural support to accommodate larger plant material and increased loading requirements.

Custom Green Roof Soil Blends

Premium Soils offers custom-engineered green roof growing media tailored to meet project-specific engineering, drainage, weight, and planting requirements. Our blends can be designed for a wide range of commercial, municipal, and urban landscape applications across BC.
