A Love Affair With Gardens on the Roof
Humans have enjoyed a love affair of rooftop gardens since the ancient civilization of Mesopotamia created a world of wonder with their elaborate ziggurats teeming with flora and fauna. Today, modern society is increasingly embracing and reconnecting on a broader scale the creation of rooftop gardens. Rooftop gardens create an oasis where people can gather for social occasions, take respite from hot summer days, and bask in the beauty of nature.
Making a rooftop garden goes beyond creating a luxurious ambiance with living greenery. There are many scientific-backed reasons a rooftop garden is an excellent idea. The plants, including trees, used in a rooftop garden help clean the air, provide cooling shade, and absorb excess moisture from heavy rainfall. Because urban environments experience “heat island effect” more than rural or suburban regions, a rooftop garden helps absorb heat and provides much-needed cooling.
Plants and humans have enjoyed a wondrous symbiotic relationship, as plants help reduce stress, anxiety, and provide healthful benefits for people. When the hustle and bustle of urban living or day-to-day modern life become too much to handle, spending time among a rooftop garden provides welcome relief, joy, and inspires awe. There are many ways to approach designing a rooftop garden that is most suitable for your space.

What is the Purpose of a Rooftop Garden?
Having a rooftop garden creates another green space that helps keep your building cooler in the summer, warmer in the winter, and adds visual appeal to your home. Use a rooftop garden to absorb water from heavy storms and give your sewer system a break. Keep a rooftop garden as a place to escape, grow fruits, vegetables, herbs, or throw a unique garden party.
Rooftop gardens are beneficial for the environment because they reduce greenhouse emissions, can harvest rainwater, provide green space for wildlife, filter toxins from the air, and produce oxygen. A rooftop garden helps a building become more energy-efficient, reflecting and absorbing excess heat, increases the longevity of a roof, and reduces the “heat island effect.” If you plant native plants and use a design where the plants are self-watering and can thrive with minimal maintenance, you get a new space to breathe easy and enjoy.
Do You Need Planning Permission for a Rooftop Garden?
Before you get excited about the idea of a rooftop garden, take pause and consider whether you will be limited or barred from doing so because of local laws or a homeowner’s association. Enthusiastic persons who live in a planned development community may have a challenge on their hands. Building a rooftop garden would significantly alter the uniform look and feel of the properties, and all the residents might not support the idea.
It is essential to consult local laws regarding what you can do to your property and talk to your local homeowner’s association if applicable. If lucky, you may create a rooftop garden with little to no problem, or you may have restrictions on how much space you can use on your roof, and how visible the garden is to the public. Some areas may have incentives to encourage homeowners and commercial building owners to plant rooftop gardens for reduced energy costs, climate change benefits, and how it benefits humans and wildlife.
The best thing is to educate yourself on how you can go about building a rooftop garden, and prepare yourself before you have to go face-to-face with an organization, or representatives for your local laws. You may succeed by using raised garden beds, container gardens, or other creative methods to achieve a rooftop garden.
Can I Use My Flat Roof as a Garden?
It is possible to transform your flat roof into an extravagant and inviting rooftop garden. You will need to consider any weight restrictions on your roof, especially when you are going to add trees, shrubs, layers of soil, planters, and other furniture. You will also need to factor in what type of design you will use, create walkways, and make sure your roof is in good repair before getting started. Don’t forget to consult local laws and your homeowner’s association before creating a fantastic rooftop garden.
