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.
This roof down in Dorset looking vibrant with lush vegetation.

Oldham Library’s green roof fully restored to how it should look after annual maintenance over the past 4 years from the TUGC team.

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:
A 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.
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 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.
The re-greening of a 1940s, West London, luxury apartment block refurbishment continued with two more garage roofs completed in quick time by The Urban Greening Company.
The 25 sq.m of sedum roof, added to a 30 sq.m. installation earlier in the year. They will help improve the water attenuation within the heavily populated and traffic congested area of Barons Court.
The project is a continuing development of our working relationship with Mike Barrett of Manorfield UK roofing. Underlining the benefit of independent, professional waterproofers working with like-minded professional green roofers.
Part of our summer work has been spent carrying out green roof remedial works on 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.
Repairing Large green roof Anglesey
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 and show how much this helps green roofs fulfil the purpose of sustainable urban drainage (suds) and biodiversity and extra biodiverse habitats in urban environments as well as ensuring they provide a point of beauty for locals.

TUGC: green roof specialists working together with waterproofers
Mike Barrett, MD of Manorfield UK roofing is the latest customer to benefit from our efficient and professional service. The installation of a sedum roof on a luxury apartment block refurbishment in west London.
“We had short notice on this job but the TUGC lads came up trumps, completing the installation in a day leaving me with a very happy client who is already talking about more projects as a result of the quality of the work done,” said Mike.
The next phase is to be completed in the near future.
