Rooftop gardens have become a popular option for commercial buildings as modern companies compete to show their commitment to the environment. However, the technology can also be scaled down to fit a single family home. Garages and additions with gently sloping or flat roofs are the typical starting place for homeowners who want to grow a garden on their roof.

Advantages of Green Roofs

Live plant and sod roofing has excellent insulating properties. It helps keep your home cool in the summer and dampens noise intrusion from outdoors. A green roof also reduces water runoff and soil erosion - rain is retained in the sod instead of draining into storm sewers.

The space on your roof can be used to support many types of vegetation. This ensures that you have some plant cover - even in winter. Grasses and mosses make a simple, easy to maintain mix. Add some wildflower seeds and your roof will bloom with color in the spring and summer. As a bonus, this garden will attract birds and butterflies. Increasing the natural habitat available in your neighborhood encourages biodiversity.

Installation Considerations

Garden roofs are significantly heavier than asphalt shingles. This means some houses must be reinforced to carry the extra weight. A membrane will be installed to keep moisture in the soil from leaching through into your home. A green roofing specialist can help you determine what system will work best with the structure of your home and for your geographical location.

Pre-planted modular units offer a couple of advantages. You don’t have to wait for your rooftop garden to grow from seed. Also, you can start small and increase the size of your garden over time.
