Green roof maintenance example

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

Encouraging Biodiversity and Invertebrates In Victoria

We have been hard at work in Victoria encouraging biodiversity through plant enhancement and increasing the diversity of wildflower mix.

The creation of habitat incidentals such as sand piles, stone mounds and log piles also attracting invertebrates to the area.

Situated on the Wagamama restaurant in Victoria.

stone mounds become a place for insects to hibernate

sand piles are created across the roof








We also installed sparrow and bat boxes to encourage a wide range of wildlife to the centre of London.

We make these bee hotels from scratch providing solitary bees with a place to make their nest

The end result is a multi functioning green roof in the heart of London with focusing on encouraging biodiversity.



Hibernacular Habitat Towers in the city.

Encouraging bees and invertibrates in the heart of the city. We installed these hibernacular habitat towers at St. Alphage gardens next to London wall.

The towers being assembled in place piece by piece

Logs and steel containers ready to be assembled









We assembled these special made steel frames and boxes and filled them with various size logs and bamboo shoots.  Creating numerous holes ranging between 0-10mm in order to attract a variety of species.

A great project in this ancient part of London.




Living wall at Bermondsey residence

A 10 metre high living wall has helped enhance a wooden decked courtyard area at three storey flat conversion in the centre of the historic leather market in Bermondsey, London.

The 30 sq.m. wall containing 1500 plants offering colour and depth in a tight compact space.

We regularly maintain this wall keeping it in good shape all year round.

Rubens Hotel Maintenance visit

We have been maintaining this exterior living wall at one of Londons top hotels The Rubens Hotel next to Buckingham Palace for 5 years now.

Our Bi-annual visits see the wall given a good haircut. We also install new plants with each visit to maintain the walls striking presence. Located in one of the busiest areas of London. This beautiful living wall is seen by thousands of people every day.

The cradle is built and dismantled on each of the three sections of the wall. This provides us with safe access and enables us to gain maximum coverage each day.

Our ongoing Maintenance has created a lush and thriving living wall. As a result we are helping combat London’s noise and air pollution levels.


Bio-solar roof to benefit Social Housing

A multi-million pound re-development in Notting Hill, London receiving a re-vamp of social housing. Working for Pavehall Plc on this interesting bio-solar roof project.

Substrate being distributed beneath the solar panels. 


The roof ready for plug planting. 









We installed four separate bio-solar roofs of approximately 600 sq.m. that will deliver low-cost green energy.

Our installation will benefit hundreds of tenants in this busy area of West London.

This project includes two core bio-diverse roof areas with over 3000 plug plants of multiple varieties.

A variety of plant species including wild strawberries

The sedum flowering on the wing roofs








We also greened a further two wing roofs of approximately 200 m2 consisting of solar panels and sedum mat.

The sedum is already established and attracting pollinators into a busy urban area showing our hard work has paid off.

Passivhaus development in Colchester

Green roof plugs planted and watering to help them thrive

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 roofs for green roof installation

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).


Start laying base for green roof

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 ready for planting

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.

Avoid green roof remedial work

Repair and install irrigation on greenroof Reigate

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 greenroof 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. Therefore helping 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.
