Green Roof Maintenance

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 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.

Green roof maintenance is often overlooked. People either think their green roof simply doesn’t need TLC or green roofs can be just be neglected.

Another common belief when a green roof is struggling is that it is simply a lost cause. Fear NOT.

At TUGC we recommend carrying out maintenance on a bi-annual basis.

Below is an example of a green roof we maintain and the difference before and after maintenance.

  • Improve and protect your asset
  • Maintain high quality vegetation
  • Keep vegetation healthy
  • Remove dry and dead thatch to reduce fire risk
  • Keep drainage channels clear
  • Maintain water attenuation to reduce flood risk
  • Improve valuable wildlife habitat areas
  • Inspect drainage outlets and other roof features such as PV panels

Re-greening by congested A4 in London

Re-greening by congested A4 in 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.

finished re-greening on the garage roof

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.

Passivhaus development in Colchester

Passivhaus development in Colchester

TUGC has just completed the installation of plug planted green roofs across three blocks of quality passivhaus dwellings in Colchester, Essex. Providing 23 new homes, a mixture of one and two bed flats and 17 houses.

Preparing the green roofs for green roofs for  installation.

We installed 800 sq.m. of green space running across the three buildings. Including an 80-120 mm build-up of substrate and 10,000 plug plants to offer broad biodiversity, as well as helping to provide sustainable drainage (SuDs).

 

Green roof base layers are being set out.

The Jerram Falkus construction includes the refurbishment of a listed Mill. This will become a shared space for social, domestic activities, and community events. The design team is led by Anne Thorne, an award winning eco-architect.

Substrate installed and the roof is ready for planting.

The buildings are designed and built to Passivhaus standards to achieve exceptionally low running costs, sustainable comfort and health.
