Environmental Benefits


Green roofs offer far reaching benefits for plants, insects’ birds and bees.

All Green roof types support wildlife and their habitats, all are valuable to varying degrees, to what level will depend on the type of substrates and vegetation layers used.

An extensive green roof will provide a natural habitat for ground nesting birds such as skylarks and lapwings.   A biodiverse roof is designed to replicate or improve the original habitat.  A wide and diverse flora and fauna, will create perfect conditions for specific plants to support the different insect and bird species.

These natural habitats in the sky help to encourage biodiversity preventing endangerment of many species, as our environment is put under increasing pressure.

Carbon Sequestration

Carbon sequestration is the process that takes place when greenhouse gases are removed from the atmosphere.  The most commonly produced greenhouse gas is carbon dioxide.  Roof vegetation layers act as a carbon sink helping to compensate for any lost greenery due to urbanization.  It has been proven that 1ha of green roof will remove up to 85kg of pollutants.

Water Management

The green roof vegetation absorbs excess water and reduces the risk of urban flooding.  A green roof compared to a conventional roof will significantly reduce the total runoff from rainwater.  Green roofs store rainwater in the plants and the growing medium (substrate) before releasing the water back into the atmosphere through evapotranspiration.

Urban Heat Island Effect

Temperatures are often higher in cities than in surrounding rural areas.   The reason behind this is known as the Heat Island effect.  Even a few degrees can make a big difference ultimately increasing the need to use air conditioning, which increases energy bills.  Green roofs provide shade and remove heat from the surrounding air, they help to moderate the heat island effect in cities and other built up areas with little vegetation.


Reduction of Noise

Nosie can be a big issue both at work and home.  Commercial office buildings and Residential houses can benefit from the installation of a green roof for the purpose of noise reduction.   Green roofs will reduce noise from external influences such as heavy traffic or areophane’s flying overhead.  Each layer of the roof plays an important part in noise reduction.   The growing medium is highly porous, and noise is reduced when low frequency sound waves enter the substrate.  Plants from the vegetation layer block higher frequency noise.  The combination of the materials used to build a green roof will help to reduce noise by up to 30% compared to a typical conventional roof.

Energy Reduction

Green roofs are beneficial when it comes to reducing energy costs,  as they offer benefits during the summer and the winter months.   In the summer the roof is protected from solar energy helping to cool the building by up to 48%.  By lowering the demand for air conditioning,  there will be a decrease in the production of air pollution and greenhouse emissions.   In the winter months heating costs are reduced as the extra layers help to insulate the building.

Increase of Longevity

A green roof system protects the waterproof membrane and further protects the roof from the sun, rain and wind. This added protection can extend the lifespan of the roof by 2 or even 3 times over the typical lifespan of a conventional roof.

Aestethically Pleasing

Green roofs have many unseen benefits, they are also visually very attractive and guaranteed to create a talking point. With the increase of green roofs across the UK we are seeing more and more aesthetically pleasing buildings as dull grey concrete and glass is replaced.

Increased Property Value

With the many benefits a green roof has to offer, there are few disadvantages.  The initial cost of installation however could be one. as the structure of the building needs to be strengthened in order to cope with the additional weight and the cost of the green roof materials are more than traditional roof materials.

Overtime you will make saving as energy bills are reduced; it is expected that you could recoup the investment in your green roof within 8 to 21 years.

Greenery on commercial buildings and residential homes have the potential to increase property value by 15 – 20%

Health & Wellbeing

Health & Wellbeing

Increasingly we are understanding the health benefits that natural greenery provides,  be it visual or physical.   As interest in green roofs across the UK grows, developers are planning more and more green spaces throughout cities, in our hospitals, care homes, workplaces and even residential houses.

Evidence has shown that when people have access to green spaces, there are direct improvements to their mental health.  The benefits include reduced stress levels, reduced muscle tension, lowered blood pressure and much more, ultimately improving general wellbeing and in some cases increased worker productivity.
