Green Roof Specialists in Yorkshire
Living roofs for garden rooms, extensions and commercial buildings. Sedum, blue and brown roof systems installed and maintained.



Green roofs from garden rooms to city rooftops
Alongside our garden work, KSSW installs and maintains living roofs across Yorkshire. From a small sedum roof on a garden office in Sheffield to a full green roof across a commercial building in Leeds city centre, the process is the same. Check the structure, get the waterproofing and drainage right, then install a system that will still look good in ten years.
Green roofs
Sedum, wildflower or grass living roofs that insulate the building, cut noise, slow rainwater and look great. Lightweight sedum systems suit most flat and gently pitched roofs on extensions, garden rooms, garages and outbuildings.
Blue roofs
Engineered to hold rainwater and release it slowly, taking pressure off drains and helping with sustainable drainage (SuDS) requirements on new builds and commercial sites. Can be combined with a green roof on top.
Brown roofs
Recycled substrate and self seeding plants that recreate brownfield habitat for wildlife. Popular with developers who need biodiversity net gain.

Green Roofs FAQs
Can a green roof go on my garden room or extension?
Yes, most flat and gently pitched roofs can take a lightweight sedum system. We check the structure and waterproofing first.
What is the difference between green, blue and brown roofs?
A green roof is planted with sedum, wildflowers or grasses. A blue roof stores and slowly releases rainwater. A brown roof uses recycled substrate and self seeding plants for wildlife habitat. We install and maintain all three.
Do you cover areas outside South Yorkshire for green roofs?
Yes. Green roof projects are quoted across Yorkshire and further afield for larger commercial work.
Do green roofs need maintenance?
A little. A couple of visits a year to feed, weed and check drains keeps a sedum roof healthy. We offer maintenance contracts.
