Most Essential Rooftop Garden Tips & Ideas You Need:

Understand Your Roof’s Load Taking Capacity:


The very first thing that you need to evaluate is how much load your rooftop can actually withstand. If you are about to set up a rooftop garden, there will be soil load, planting pot load. There will be a significant amount of load of the furniture and the equipment as well. If there is too much load on your rooftop that it can’t support, it can be hazardous to your house. So seek the advice of a licensed structural engineer who can evaluate this stuff and can give a design about how to set up a fuss-free rooftop garden. Going for false floors also helps in evening out the total weight or load.

Choosing The Plants:

Avoid plants that have an elaborate root system. As you are going to put your plants in containers, plants with limited root systems are recommended. In addition, if a plant does not have a limited root system, it will require way more soil to thrive. That is possible in a container.

The second thing you need to consider is the heat issue. It is evident that the plants you get on your rooftop garden will be subjected to a lot of open sun exposure. The high the roof, the more will be sun exposure. So you need to choose plants that can withstand heat.

Understanding The Hardiness Zone Of A Plant:

‘Hardiness Zone’ or simply ‘Zone’ is a widely-used system based on the extreme minimum temperature bearing capability of a plant that has been developed by the USDA. There are a total of 13 zones and if you are trying to get the best-suited plant for your rooftop garden or backyard garden, you must take this system as a guide.

Plants like lettuce, spinach, kale, different flowering small plants, shrubs – these are the best that you can go for.

Watering Your Plants:


If you are setting up a rooftop garden, there will be a need for a good source of water supply. You need to water your plants at least once a day. During the dry and summer months, the need is even higher. The best way to water your plants is to install a fuss-free drip irrigation system. It effectively provides necessary moisture to the soil, making sure that no excess water is wasted. Also, it does not cause damage to the saplings and stems. Drip irrigation is essential because it gives your plants adequate water at regular intervals. It is better to know that installing drip irrigation system requires a higher amount of initial investment. So do your math beforehand.

Drainage And Rooftop Waterproofing:


Next most important things are a good drainage system and rooftop waterproofing that you must consider. Well-drained soil ensures the good health of plants and also good health of your rooftop. You must waterproof your roof beforehand to hinder damage caused by water. Secure your roof with a good roof membrane that can stop any water penetration.

Choosing Proper Containers:


Light-weight but large containers are the best for your rooftop garden. For that plastic containers are better than traditional material pots like clay or cement. In addition to that, good looking pots also add to the beauty and aesthetics of your rooftop.

Another factor is the heating mechanism of your containers. If your roof gets too much sunlight, clay or cemented pots will catch the heat quickly and it will heat up the soil and the soil will get dried up in no time. If that happens, your plant will get dehydrated and will need more watering. So, self water pots are better for that. Also, if your plants are top-heavy, chances are they will lose balance and will fall if the containers are way more light. Windy weather will worsen the situation. So consider all these scenarios and then choose your plant containers.



Sunlight is one of the most essential things needed for a living being. So your plants need good amount of sunlight to thrive well. There are plant species that can withstand a high amount of direct heat. There are also plants that thrive the best when there is a good combination of sun and shade. So before buying your plants, consider how much sunlight your rooftop garden gets. If your rooftop is shady and does not get enough sunlight, consider planting species like Big Daddy Hosta. Plants that are hardy in Zones 3-8 are low maintenance and best for these kinds of roofs.

Having a rooftop garden is certainly a very beautiful idea. It offers you solace, privacy, and your own green space. And at the same time, it does wonder to the environment in a highly polluted urban area. Paint your pots colorful, have more flowering plants that bloom into a burst of colors, and enjoy your quality time amidst the greenery when you are spending your leisure. And these were some of the most important rooftop garden tips and ideas that will surely help out in building your dream green space.
