Recent green roof restorations

Recent green roof restorations carried out by TUGC.

The two seperate case studies below highlight two examples of how green roofs might fail.

There can be numerous factors resulting in failing green roofs.

Many clients write off their green roof if there are issues but we can highlight the issue and provide solutions.

Case Study 1:

small green roof on a residential property in Islington.

We replaced the sedum which was failing due to limited light exposure. We stripped the sedum, created a higher depth of compost and soil blend and replanted a mixture of shade tolerant ferns, grasses and ivy’s.

 

Case Study 2:

The first picture below shows a green roof just after installation last summer at Beckenham Methodist Church. The roof light and glass were fitted after the green roof and the second picture shows the roof completely trashed from traffic back and forth. Third picture is after our return to add extra substrate and sedum to the roof. We see too many roofs trashed from other workmen and trades, It’s not a nice sight and hopefully fewer incidents like this occur. Having said this they are always salvageable and we are more than willing to help on any green roof restorations.
