A selection of healthy, good green roofs from our recent maintenance travels. The below are just some of the best green roofs we have come across this year.

We carry out a lot of green roof maintenance across the UK throughout the spring and Autumn. At TUGC we recommend bi-annual maintenance on most green roofs. These pictures below are from our recent spring/summer maintenance visits.

When a green roof is installed correctly using a quality system and regular maintenance is upheld the benefits are proven.

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.

green roof maintenance

These are all examples of recent green roof maintenance carried out by the urban greening company team.

They are all perfect examples of how a green roof should look for this time of year with autumn coming to an end. However they have not always looked this good. We always recommend bi-annual maintenance visits and it is thanks to this maintenance that these roofs are looking so great.

Case Study 1

The roof below is situated at a care home in Highgate, North London. Residents look straight out onto the roof from their windows and seeing lush vegetation is something we want for them to enjoy. A couple of years ago this roof was not in the best of shape. Bi-annual green roof maintenance has seen the roof improve with each visit.

Using a bauder specialised fertiliser in the spring supplying the roof with much needed nutrients for the coming summer months and removing any weeds. This has seen the sedum flourish and we now see sedum coverage across the whole roof.

Case Study 2

Another example below but this time a wildflower roof. Historically this roof could be quite patchy and not have a huge amount of  vegetation coverage. Through extensive weed removal and keeping on top of any invasive vegetation we have seen wildflowers thrive. This picture shows some white star jasmine trailing onto the roof for added aesthetics.

Case Study 3

The clients on the next roof were concerned about bare patches on their green roof in the heart of the city of London. As this was our first visit we decided to add extra sedum cuttings along with some generous amounts of substrate to act as a growing medium. Upon our return we were pleased to see this had worked. It is now a case of keeping on top of this roof with regular maintenance to keep it in top condition.

Sedum Roof for Methodist Church

Sedum Roof installed at Beckenham Methodist Church, South East London. The Church is currently being renovated and this green roof was added onto an extension of the building. We finished the job in one day which consisted of many tricky cuts of drainage board and sedum.

Cutting around the numerous roof lights meant for a neat and tidy finish between small areas of vegetation and stone.

We used a low depth of substrate  on this roof. Due to access restrictions the drainage, fleece, substrate and sedum was carried up onto the roof by hand which wasn’t the easiest of tasks.

The roof will fit in nicely with the surroundings and will add some important green infrastructure to this area of South London.
