Green Roof Systems

Our Green Roof Systems

At Bell Sustainable Roofing, our design team boasts extensive experience in a wide range of green roof projects, equipped with the technical expertise to deliver systems that excel in performance throughout the building’s lifetime.

Green roof systems are increasingly favoured by specifiers aiming to mitigate the environmental impact of buildings while enhancing green spaces, especially in urban settings. Our green roof solutions not only improve aesthetics but also provide numerous environmental benefits.

Types of Green Roof Systems

Extensive Green Roof Systems

Extensive green roof systems are the most practical option, featuring a thin layer of growing medium and vegetation that require minimal care and maintenance. These systems are lightweight, making them suitable for a variety of buildings without the need for significant structural modifications. Extensive green roofs typically use hardy, low-maintenance plants such as sedum, grasses, and mosses, which thrive in various weather conditions with little intervention.

Intensive Green Roof Systems

Intensive green roof systems are designed for larger plants and trees, requiring a substantial soil depth and entailing higher maintenance levels. These systems can support a diverse range of vegetation, including shrubs, perennials, and even small trees, creating lush, garden-like environments. Intensive green roofs are ideal for spaces that will be used for recreation or aesthetic purposes, providing significant ecological and social benefits.

Biodiverse finishes

A biodiverse roof finish enhances the ecological value of a building by creating a living roof system designed to support a wide range of native plant and animal species. By incorporating varied substrates, natural planting schemes, and habitat features such as logs, stones, and wildflower areas, these roofs replicate natural environments and encourage biodiversity in urban settings. This approach not only improves habitat connectivity for pollinators and wildlife but also contributes to environmental resilience. As a result, biodiverse roof finishes help developments achieve higher sustainability standards while promoting long-term ecological benefits and reducing overall environmental impact.

Biosolar finishes

Incorporating biosolar finishes further advances the performance of sustainable roofing systems by combining green roof technology with integrated solar photovoltaic panels. By installing solar arrays in conjunction with vegetated roof systems, this approach enables efficient renewable energy generation while maintaining the ecological benefits of a green roof. The vegetation can help improve panel efficiency by reducing ambient temperatures, while the panels provide partial shading that supports diverse plant growth. This synergy allows buildings to optimise energy output, enhance biodiversity, and achieve higher sustainability standards while reducing overall carbon emissions.
