Certified Sedum Green Roof System
The Certified Sedum Green Roof System is our specification-grade extensive build-up. Every layer is documented with BBA-certified data sheets, U-value calculations, FLL drainage performance, fire ratings and FM Global wind uplift. Designed for tender submissions, planning conditions and BREEAM credits where 'a sedum roof' isn't enough - you need traceable, certified component data.
Industry-certified sedum green roof build-up with documented U-values, drainage rates, weight calculations and BBA data for architects and specifiers.
Frequently asked questions
Why specify a certified sedum system over a standard one?
Certified systems carry independent BBA, FLL and FM Global data - essential for tender submissions, BREEAM credits, planning conditions and projects where insurers or building control require documented performance.
Do you provide CAD details and specification documents?
Yes. We supply NBS-format specifications, layered CAD details (typical edges, upstands, outlets) and full data sheets for every layer on request.
Can the Certified Sedum system support BNG credits?
Sedum roofs typically deliver low BNG uplift on their own. For projects targeting biodiversity credits, our Biodiverse Green Roof System is the better starting point - both can be combined on the same building.
About The Green Roofer
The Green Roofer designs, supplies and installs green roofs for homes, developers and commercial buildings across the UK, with strong coverage in Essex, Southend-on-Sea, Chelmsford and London. We work on everything from a single garden shed or extension to large commercial flat roofs. See our residential green roof services or our commercial roofing services.
Our systems include sedum roofs, biodiverse and wildflower roofs, intensive roof gardens, blue roofs for stormwater attenuation and bio-solar roofs that combine planting with solar panels. Smaller projects are welcome too, including a green roof for your shed. We also supply green roof materials UK-wide for trade customers and DIY projects: complete systems such as the certified sedum green roof system, traditional green roof system, biodiverse green roof system and lightweight biodiverse system, plus individual components including sedum mats, wildflower mats, green roof substrate, drainage board, filter fleece, protection fleece and decorative cobbles.
Every project starts with a free site survey and a clear, no-obligation quote. We check roof structure, load capacity, waterproofing and drainage before recommending a system, and we offer ongoing green roof maintenance so the planting stays healthy year after year. Green roofs help manage rainwater, improve insulation, extend the life of the waterproofing beneath them and support biodiversity, including Biodiversity Net Gain requirements on new developments.
