A well-planned rooftop garden can be a true oasis in the midst of the bustling city. Not only do they provide a peaceful escape, but they also offer a chance to connect with nature and grow your own food.
Rooftop gardens can be built on a variety of surfaces, including concrete, wood, and even metal. With the right design and materials, you can create a lush and vibrant space that's perfect for relaxation or entertainment.
The key to a successful rooftop garden is proper drainage and ventilation. This helps prevent waterlogged soil and reduces the risk of mold and mildew growth, ensuring your plants stay healthy and thrive.
A rooftop garden can also increase the value of your property, making it a great investment for homeowners. By incorporating plants, greenery, and other design elements, you can create a unique and inviting space that sets your home apart from the rest.
Types of Gardens
Rooftop gardens come in three main types, each with its own unique features and purposes.
Extensive green roofs are low-maintenance and have a thin, lightweight growing medium, typically around 3 to 6 inches deep.
They're perfect for flat or low-sloped roofs and can even help with stormwater management.
Semi-intensive green roofs offer a mix of both extensive and intensive green roofs, with a growing medium depth of around 6 to 12 inches.
This type of rooftop garden is ideal for long-term care facilities, daycare play spaces, and urban picnic areas.
Intensive green roofs, on the other hand, have deep soils with a growing medium depth of more than 6 inches.
They offer a great potential for highly creative designs and biodiversity, and can even support small home gardens, playgrounds, and full-scale parks.
Design and Planning
A rooftop garden can be a tranquil oasis, but it requires some careful planning. It's essential to decide if the space will be dedicated only for growing plants or if it will function as an outdoor living space as well.
Consider the mature size of plants to avoid obstructing the view. For example, plants like succulents can be used to intercept rushing rainwater and add a touch of greenery to the space.
Mixing plant types can add variety to the design, but it's also important to create a focal point. This can be a stunning plant specimen, a water feature, or even a gorgeous piece of pottery used as a container.
Here are some key design considerations to keep in mind:
- Limit the design to no more than 3 colors to avoid clutter and busyness.
- Choose a main focal piece and design everything else around it.
- Consider ambient lighting to create an inviting atmosphere after dusk.
- Make sure to include lighting near the stairway or door for safety reasons.
Debunking Green Roof Myths
Green roofs are not just for show; they can actually help reduce stormwater runoff, which can be a major issue during heavy rainfall.
You might think that a green roof is too heavy for a building, but the truth is, they're designed to be lightweight and can be built on top of existing roofs.
Some people assume that green roofs require a lot of maintenance, but the truth is, they can be relatively low-maintenance, especially if you choose plants that are resistant to drought.
Green roofs don't have to be expensive; in fact, they can be a cost-effective way to reduce energy bills and improve air quality.
A green roof can be a great way to create a peaceful oasis in the middle of a bustling city, but it's not just about aesthetics - it can also provide insulation and reduce energy costs.
Garden Planning Considerations
As you start planning your rooftop garden, it's essential to consider a few key factors to ensure it's both functional and beautiful.
Decide if the space will be dedicated to growing plants or if it will also function as an outdoor living space. Having a seating or hangout space within the garden is a great use of space and makes it multi-functional.
Think about the mature size of plants you'll be using. More often than not, plants are bought when they're immature, and still have growing to do. This means you'll need to consider what the height of mature plants will be and choose specimens that tend to stay more compact or dwarf to keep from impeding the view.
Mixing different plant types can add variety to your design. Consider combining shrubs, ornamental grasses, and flowering perennials with ornamental annuals and vegetables to create a visually appealing space.
Raised garden beds can add a small amount of vertical height within your design. To prevent roots from growing through and damaging the building's roof, consider placing the beds on casters or spacers to keep the bottoms up off the roof.
A main focal piece can help tie your entire design together. This could be something like a water feature, a stunning plant specimen, or even a gorgeous piece of pottery used as a container.
Limiting your design to no more than 3 colors can help prevent it from looking cluttered and busy. Choose one primary color for the main design element, with one or two others acting as accents. Neutral colors like beige, white, and grey make great accents and help draw out the beauty in the plants.
Consider adding lighting solutions if your rooftop garden will be used for entertaining or as a living space. Ambient lighting can create a relaxing atmosphere after dusk and extend the time the space can be utilized. Don't forget to make it a little brighter by the stairway or door for safety reasons.
Here's a quick reference guide to help you remember these key considerations:
- Decide on a dedicated use for the space (plants or living space).
- Choose compact or dwarf plants to prevent obstructing the view.
- Mix plant types for variety.
- Use raised garden beds with casters or spacers.
- Design around a main focal piece.
- Limit your color palette to 3 colors.
- Consider lighting solutions for evening use.

A rooftop living area is a great place to observe the changing seasons and enjoy the outdoors, even in the midst of a busy city. You can watch the flowers bloom in the spring, the leaves change in the fall, or the snow fall in the winter.
Starting a Chicago Garden
If you're in a shared space, you'll need to check with the landlord or building superintendent about attaining roof rights or to ask what roof access you are granted. This can be an expensive and cumbersome process.
Most of the time, you'll have to petition your idea for a rooftop garden to the building's board or council, and then you must receive at least 75% approval before you can obtain rights and begin construction. Working with an experienced rooftop landscape architect can save you a lot of time and money.
Before starting your project, it's essential to get in contact with a contractor or the building engineer to assess the condition of the roof and help establish a list of necessary finances. If you decide to tackle this project solo, you alone will bear the burden of all insurance costs, maintenance fees, materials, and other expenses.
To develop a plan, consider the layout of your rooftop garden, the number of garden beds you'd like to have, whether or not you'd like raised containers, what kinds of plants you intend to grow, and more. Opt for sturdy materials, such as large half-barrel planters, which are unlikely to dry out or topple over under windy conditions.
Here are some key considerations to keep in mind as you plan your rooftop garden:
- Sturdy materials: large half-barrel planters, raised garden beds at least 10-inches deep
- Water supply: automatic watering systems can be installed to alleviate the constant lugging of watering cans up to the roof and back
- Roof access: check with landlord or building superintendent to determine what roof access you are granted
