Covering a building’s roof with grass or vegetation to create a Green Roof isn’t a new idea, the so called sod churches and farms of Iceland and Norway, used peat and turf as roofing materials as far back as the 18th Century.
Modern greenroofs have been incorporated onto everything from domestic housing to high rise office blocks, and confer many advantages – including absorbing water to reduce storm water run-off and flash flooding risk, providing good insulation properties, reducing urban heat island effects, and providing a much needed addition to ecological habitat in many urban settings.
In addition they also look nice !
Small build, or even DIY, installations of greenroofs on domestic homes, garages and sheds is becoming more and more popular, and a wide array of advice and support is available, as are a number of ready made kits !
