Greener rooftops for cleaner, cooler, and more resilient cities
Green roofs, also known as living roofs, transform rooftops into vibrant, functional green spaces. They offer a sustainable solution for managing rainwater, reducing energy use, and improving air quality in our increasingly built-up cities.
By absorbing rainfall, cooling buildings, and supporting urban biodiversity, green roofs help combat the effects of climate change while enhancing the wellbeing of those who live, work, and learn beneath them.
Green buildings and green roofs have become new weapons in the fight against climate change, with hundreds of cities around the world promoting environmentally friendly building techniques to reduce pollution from buildings and structures.
Benefits
Green roofs support climate resilience by reducing stormwater runoff, cooling buildings, supporting pollinators, and improving air quality in dense urban areas.
Manages Rainfall
Green roofs absorb and retain rainwater, helping reduce peak flow and prevent localised flooding.
Boosts Energy Efficiency
They insulate buildings, reducing heating needs in winter and cooling demands in summer.
Supports Biodiversity
From sedum to wildflowers, green roofs provide essential habitat for birds, bees, and insects.
Improves Air Quality
Plants filter particulates and convert CO₂ to oxygen, helping combat urban air pollution.
Local authorities
Green roofs help manage stormwater, improve air quality, and reduce the urban heat island effect. They enhance community spaces, support biodiversity, and contribute to climate-resilient infrastructure.
Education
Green roofs provide outdoor learning opportunities, improve thermal comfort in classrooms, and support biodiversity on school grounds. They create engaging, healthy environments for students and staff.
Commercial
Green roofs improve building insulation, reduce energy costs, and enhance a company’s green credentials. They also boost staff wellbeing and increase the value and appeal of commercial properties.
BIDs
Green roofs contribute to cleaner air, cooler streets, and greener skylines. They’re a visible commitment to sustainability, improving the urban environment and strengthening local identity.

Frequently Asked Questions
What is a green roof?
A green roof is a layer of vegetation planted over a waterproof system installed on top of a flat or slightly sloped roof.
Can a green roof add value to a property?
Yes – green roofs can increase property value through better energy efficiency, longevity, and environmental credentials.
Do green roofs help with flooding?
Yes, they absorb and retain rainfall, reducing runoff and easing pressure on urban drainage systems.
Do green roofs need maintenance?
Yes, all green roofs need some maintenance. Extensive roofs need minimal care, while intensive roofs require regular upkeep.
How long does a green roof last?
With proper installation and care, a green roof can extend your roof’s lifespan by 20 to 30 years.
Can green roofs be installed on sloped roofs?
Green roofs can be installed on slopes up to 45°, though additional support systems may be needed for steeper pitches.
Are there different types of green roofs?
Yes, extensive green roofs are lightweight and low-maintenance, while intensive green roofs resemble rooftop gardens and support deeper planting.
