Living Roofs and Rooftop Gardens Boast Beauty and Sustainability
Living roofs, also known as green roofs, are a fantastic way to blend nature with architecture. Imagine transforming your roof into a lush green space filled with plants and flowers. It’s not only beautiful but also highly beneficial.
Here’s why you might consider a living roof:
- Environmental Benefits: Living roofs help absorb stormwater, reduce runoff, and improve air quality.
- Energy Savings: They offer natural insulation, keeping your home cooler in the summer and warmer in the winter.
- Aesthetic Appeal: They provide a unique, eye-catching look that’s sure to impress.
Living roofs are becoming increasingly popular for their ability to lower energy costs and support the environment. If you’re interested in enhancing your outdoor space with a living roof, our team at Borst Landscape & Design can get you started with a vibrant rooftop garden.

What is a Living Roof?
Types of Living Roofs
A living roof is more than just a patch of greenery on top of a building. It’s a complex system that offers various benefits and comes in different types to suit your needs. Let’s break down the essentials.
1. Extensive Living Roofs
- Lightweight and Low Maintenance: These roofs are ideal for residential homes. They use a shallow layer of soil, typically 1.6 to 5 inches deep, making them lighter and less demanding to maintain.
- Self-Sustaining: Extensive roofs generally require minimal intervention, with only annual weeding necessary. They’re perfect if your roof is hard to access.
- Vegetation: Expect to see drought-resistant plants, which are great for reducing water use.
2. Intensive Living Roofs
- Heavier and Rich in Features: Think of these as rooftop gardens. They can handle 80 to 150 pounds of vegetation per square foot and may include features like small ponds.
- High Maintenance: Intensive roofs need regular care, much like a traditional garden. They’re more suited for commercial or municipal buildings.
- Deep Soil: With 7 to 24 inches of soil, these roofs can support a wide variety of plants, including small trees and shrubs.
3. Semi-Intensive Living Roofs
- Middle Ground: These offer a balance between the extensive and intensive types. They require moderate maintenance and support a wider variety of plants than extensive roofs.
- Versatile Vegetation: You can enjoy a mix of shallow and deep-rooted plants, providing both beauty and biodiversity.
Waterproof Membrane and Layers
No matter which type you choose, all living roofs start with a waterproof membrane. This crucial layer prevents water damage to your building. Above it, layers for water and soil retention are added, often using materials like pumice or clay. Finally, the root-growing substrate, made from a mix of organic and inorganic materials, supports the vegetation.
Choosing the right type of living roof depends on your building’s structure and your personal preferences. Whether you’re looking for a low-maintenance option or a lush garden in the sky, there’s a solution for everyone.
Benefits of Living Roofs
Environmental Benefits
Energy Efficiency and Air Quality
A living roof does wonders for energy efficiency. By acting as natural insulators, these roofs reduce the need for heating in winter and cooling in summer. This not only saves energy but also lowers utility bills. Additionally, the plants on a living roof help clean the air by absorbing pollutants like nitrogen dioxide and sulfur dioxide, contributing to better air quality.
Stormwater Management
One of the standout features of living roofs is their ability to manage stormwater. They absorb a significant amount of rainwater, reducing runoff by up to 80% compared to regular roofs. This helps prevent flooding and reduces the burden on urban drainage systems. Moreover, they release the absorbed water slowly, which is beneficial for urban water conservation.
Biodiversity and Urban Heat Island Mitigation
Living roofs create habitats for a variety of species, including birds, bees, and butterflies, promoting biodiversity in urban areas. They also combat the urban heat island effect by cooling the air through evapotranspiration, making cities more comfortable during hot months.
Carbon Sequestration
By storing carbon dioxide, living roofs play a role in reducing greenhouse gases. This helps in the fight against climate change, making them a sustainable choice for eco-conscious homeowners.
Economic Advantages
Energy Savings and Lifespan Extension
Living roofs contribute to significant energy savings, reducing the need for air conditioning and heating. This translates to lower energy bills. Additionally, they protect the underlying roofing materials from extreme weather and UV radiation, effectively doubling the lifespan of a conventional roof. This means fewer replacements and long-term cost savings.
Cost Savings
While the initial investment for a living roof might be higher, the reduced energy bills and extended roof lifespan offer substantial savings over time. Plus, many cities offer incentives like tax credits to offset the initial costs, making living roofs a smart economic choice.
Social and Community Impact
Mental Health and Educational Spaces
Living roofs offer a peaceful retreat from the urban hustle, providing a necessary connection with nature. This can reduce stress and improve mental well-being. They also serve as excellent educational platforms, where schools and communities can learn about ecology and sustainable practices.
Community Gatherings
These green spaces can be transformed into unique venues for community events and gatherings, enhancing social interactions and community bonding. They can become tranquil spots for relaxation or even lively spaces for social events, adding value to urban living.
Considerations for Installation
When considering a living roof, it’s important to evaluate the structural requirements and maintenance needs to ensure a successful installation.

Irrigation Systems
A well-planned irrigation system is crucial, especially for intensive roofs. Access to water is necessary to help plants thrive. Some systems are designed to be self-sustaining, using rainwater retention methods.
Lifespan
A living roof can significantly extend the lifespan of the underlying roof materials. By protecting against UV rays and extreme temperatures, living roofs can double or even triple the life of a conventional roof. This longevity translates to fewer replacements and reduced waste, aligning with sustainable building practices.
