If you picture a roof, you probably see a flat, grey surface, forgotten and lifeless. But what if our roofs could be something more?

Green roofs turn that image on its head. Made from a layer of sedum, wildflowers, and other lush plants, these living roofs are a powerful way to bring natural life back into our environments, all while making buildings look breathtaking.

Here at Hampshire Green Roofing, we’re big believers in the many benefits green roofs offer homeowners and businesses. Let's dive into why biodiversity is important, how green roofs create it, and why you should consider adding one to your building!

Why Does Biodiversity Matter?

Biodiversity refers to the variety of plants, animals, fungi, and organisms that share our planet. Here’s why it’s so essential:

  • A rich mix of plants, animals, and microorganisms creates a complex web of interactions that keeps ecosystems running smoothly. It provides us with clean air to breathe, fresh water to drink, and a stable climate - the very things that keep us healthy and thriving.
  • Healthy ecosystems provide us with essential services like food production, pollination, flood protection, and disease control. For example, diverse insect populations are crucial for pollinating crops, while a variety of plants helps purify water and prevent soil erosion.
  • A diverse ecosystem is more resilient to change. With many species playing different roles, the system can adapt to challenges like climate change or invasive species. A monoculture, with only one or a few species, is much more vulnerable to collapse.
  • Biodiversity is simply what makes our planet a beautiful and fascinating place to live!

Sadly, biodiversity faces many challenges. Urbanisation often creates "heat islands" and disrupts natural habitats, even pushing some species to the brink of extinction. Fortunately, there are many ways we can help restore biodiversity, and one great solution is green roofs.

How Do Green Roofs Encourage Biodiversity?

Green roofs create a miniature ecosystem right on your rooftop, turning it into a precious green space in the urban jungle. Here are just some of their biodiverse benefits:

 

Food and Shelter

The plants on a green roof provide a source of nectar and pollen for pollinators like bees and butterflies, while also offering seeds and berries for birds. Invertebrates like beetles and spiders can also find food and shelter amongst the vegetation.

 

Habitat Diversity

By incorporating features like log piles, sandbanks, or even small ponds, a green roof can be designed to create a variety of microhabitats, allowing a wider range of creatures to call it home.

 

Stepping Stones

Green roofs, especially when linked together across buildings, can act as stepping stones for wildlife, allowing them to move between fragmented patches of habitat in urban areas.

How Else Are Green Roofs Sustainable?

The eco benefits extend beyond biodiversity. Green roofs can soak up rainwater and reduce runoff that can overwhelm storm drains, purify the air by filtering out pollutants, and even help keep your building cool in the summer and warm in the winter thanks to their insulating properties.

Who Benefits from a Biodiverse Green Roof?

Homeowners

Green roofs are a dream come true for birdwatchers, gardeners, and anyone who loves nature! A variety of flowers attracts a vibrant mix of bees, butterflies, and hummingbirds to your garden, which flit between your green roof and your garden flowers and provide a bumper crop of fruits and vegetables. The diverse insect life on your green roof also attracts helpful predators which help keep pest populations in check without harmful chemicals. Finally, a biodiverse garden is more resilient to pests and diseases, as a healthy balance of insects and microbes makes your plants better equipped to fight off invaders and recover from damage.

Business Owners

Large rooftops on commercial buildings are prime real estate for green roofs. They let you showcase your green credentials by creating a bustling rooftop habitat, attracting eco-conscious customers and boosting employee morale with nature right outside their windows. They also transform drab rooftops into stunning living landscapes, adding a whole new dimension to your property's kerb appeal.

Frequently Asked Questions

There are many benefits to installing a green roof. They reduce storm-water runoff to reduce the risk of flooding in drainage basins; they reduce energy use of heating and air-conditioning by insulating the roofs and keeping the building warmer in winter and cooler in summer; a roof’s lifespan is increased by reducing heat fluctuations and UV exposure which degrades roof membranes; they help to mitigate the effects of global warming; the urban heat island effect is lessened in large cities; air and water quality is improved; they act as noise insulation and can reduce noise transfer by 8 decibels; they increase biodiversity and reclaim land lost by development and urban sprawl; and of course, they look beautiful!

In most cases where green roofs are installed on existing buildings, planning permission is not required. However, it is always advisable when making any kind of alteration to a building to contact your local planning department.

Green roofs can be created on flat or pitched roofs. Ideally, a green roof will go on a slope up to 10° but if it's on a slope over 20°, make sure you have a frame to stop the green roof from slipping. First, a layer of waterproofing needs to be added to your shed or garage.

Green roofs last 40 years or more and attract wildlife such as birds, bees and spiders.

In addition to thermal insulation, a green roof also has a sound-insulating effect. The combination of substrate, plants and the embedded air in the green roof system provide good sound insulation. Sound waves are absorbed and reflected.

Yes. Green Roofs are 'Low-Maintenance' not 'No-Maintenance'. Green roof maintenance is generally a very simple process. They are designed so that they will not require endless hours keeping them looking at their best.
