Commercial Green Roofing Systems

A green roof system (also known as a living roof) is a roof covered in vegetation such as grass, shrubs or even trees, all planted on top of a waterproofing membrane. Green roofs have proven an increasingly popular choice for commercial properties due to their strong environmental and economic sustainability compared to other styles of roofing.

Maguire Brothers provide expert installation of commercial green roofing systems, allowing our clients to upgrade their roof and accomplish sustainability goals all while providing numerous benefits to the local community and ecosystem.


The Benefits of Commercial Green Roofing

Our team work closely with you to create a green roofing solution that will enable you to take advantage of the many benefits of commercial green roofing, including:

Promoting Biodiversity in Urban Areas​

In urban environments, green roofs create safe habitats for wildlife, allowing insects, birds, and plants to flourish. This significantly enhances urban biodiversity, providing much-needed refuge in areas that are typically inhospitable to nature. This is especially advantageous in large cities where natural spaces are scarce.

Thermal Protection & Reduced Energy Use​

Installing a green roof can lead to substantial energy savings. Green roofs help regulate indoor temperatures, reducing the need for heating and cooling throughout the year. The vegetation on green roofs reflects sunlight, thereby cooling the building. As climate change progresses, sustainable cooling methods will become increasingly crucial, and green roofs offer an attractive, eco-friendly solution to alleviate some environmental stress.

Improved Air Quality​

A green roof can enhance the air quality of your commercial property by filtering and absorbing airborne pollutants and particles. In areas with high pollution levels, this means reducing toxins, creating a safer and healthier environment.

Retaining & Purifying Rainwater

Green roofs are effective in retaining and purifying rainwater. By absorbing rainwater, they lessen the burden on sewer systems, thereby reducing water waste. Additionally, they filter out pollutants, preventing them from entering other water streams and channels, thus improving overall water quality.

What are the Different Types of Green Roof?

Green roofs fall into 3 basic categories, depending on the thickness of their vegetation layer and the amount of maintenance they will require; the thinnest and simplest green roofs are called ‘extensive’, while the thickest and most demanding are called ‘intensive’. The third category, ‘semi-intensive’, refers to green roofs that exist in-between those two extremes.

How Should a Green Roof Be Looked After?

Green roofing systems should be weeded once or twice a year and watered frequently during periods of hot dry weather.

Additionally, the vegetation should not be walked on. ‘Sedum’ roofs (roofs with vegetation that’s made up of self-perpetuating, shallow-rooted plants) need to be fed with fertiliser once a year, in the spring.

Are There Any Other Green Roof Benefits?

Decreased Flooding Risk: A living roof helps decrease the risk of flooding due to its rainwater retention and reduced run-off.

Mitigation of ‘Heat Island’ Effect: Built-up towns and cities typically act as a ‘heat island’ that get much warmer than rural areas. The plants and soil on a green roof can mitigate this effect by absorbing some of the heat.

Enhanced Lifespan of Waterproof Membranes: Green roofing systems result in an increased lifespan of waterproof membranes thanks to their protection by the landscaping.

Improved Soundproofing: Vegetation on the roof provides an organic source of additional soundproofing for the building.
