Rooftop garden

A rooftop garden is a planted outdoor composition built on a roof deck or terrace, usually layered with waterproofing, drainage, root protection, and growing medium. It is defined by greenery in planters or continuous beds, often paired with timber, stone pavers, gravel, and metal edging. The look is typically light and resilient, with a mix of soft planting and hard-wearing surfaces that can handle wind, sun, and limited soil depth.

Frequently asked questions

Do rooftop gardens need special roof construction?

Yes. They need proper waterproofing, drainage, and structural review so the roof can support the added load from soil, plants, water, and people.

What plants work best on a rooftop garden?

Low-maintenance, wind-tolerant, and sun-tolerant plants usually perform best, such as grasses, sedums, shrubs, and selected perennials depending on climate.

Can a rooftop garden also be used for sitting or dining?

Yes, many include seating or dining areas, but the layout should leave enough clear space for circulation and keep heavier elements where the structure allows.
