Product Description

Sedum green roofs help manage rainfall at source by retaining and slowing runoff, while also improving the appearance of flat roofs and supporting biodiversity. The Sedum Roof Kit for Flat Roofs combines drainage, water retention, growing media and vegetation layers into a coherent system designed specifically for smaller roof areas.

The pre grown sedum blanket provides instant coverage using plant species well suited to extensive green roofs. Sedum is resilient, low maintenance and tolerant of dry conditions once established, making it an ideal choice for domestic flat roofs.

This kit is well suited to garages, bin stores, cycle shelters and similar structures where a lightweight green roof solution is required. Structural suitability and waterproofing should always be confirmed before installation.

Additional Information

System Breakdown

Each Sedum Roof Kit for Flat Roofs includes the following system components:

Sedum vegetation layer

A pre grown sedum mix blanket forms the visible green roof surface, providing instant green coverage with no additional planting required.

Growing media layer

A lightweight growing medium supports root development and contributes to water retention across the roof without adding unnecessary load.

Drainage and water retention layer

A profiled drainage layer manages excess water while retaining moisture for plant use, helping to reduce runoff during rainfall and support healthy growth.

Protection and filtration layer

A geotextile layer protects the waterproofing beneath and prevents fine particles from blocking the drainage layer, supporting long term system performance.

System accessories

Supporting items such as sedum conditioner and compatible system components are included as part of the complete kit.

  • Garage roofs
  • Flat roof outbuildings
  • Bin stores and refuse enclosures
