Avoid remedial work with regular maintenance

Repair and install irrigation on greenroof Reigate

Part of our summer work has been spent helping recover two large unmaintained roofs – one a 2,000 sq.m. roof on a school in Anglesey, the other being a lovely, 300 sq.m. sloping roof on a church in Reigate. Both needed replacement sedum across areas of the roof and a heavy dose of organic fertiliser to give them a chance of recovery. We also installed an irrigation system on the Reigate church to help the sedum cope with the gradient of the roof.

Access was an issue at both sites with no design consideration for roof maintenance, but use of scaffolding towers helped reduce the pain, although seagulls’ nesting at Anglesey created a challenge!

Both sites provide a clear example of the need for regular maintenance to help green roofs fulfil the purpose of sustainable urban drainage (SuDs) and biodiversity in urban environments as well as ensuring they provide a point of beauty for locals.
