Rooftop garden

A rooftop garden is a planted outdoor layer built on a roof, usually formed with a waterproof membrane, root barrier, drainage, growing medium, and hardy vegetation. It is defined by lightweight materials, weather-resistant finishes, and planting that can handle wind, sun, and shallow soil depth. Common elements include pavers, gravel, planters, seating, and sometimes shade structures or irrigation.

Frequently asked questions

Can any roof become a rooftop garden?

Not every roof is suitable. The structure needs enough load capacity, proper waterproofing, and drainage details before planting can be added.

What plants usually work best on a rooftop garden?

Drought-tolerant and wind-resistant plants are usually the safest choice, such as sedums, grasses, herbs, shrubs, and compact perennials, depending on climate and sun exposure.

Does a rooftop garden need a lot of maintenance?

Maintenance varies by planting scheme, but it usually needs regular watering, seasonal pruning, drainage checks, and occasional replacement of plants exposed to harsh weather.
