Unfortunately, only two handful of these meet the needs of plants or our criteria. Installing an efficient irrigation system is essential for maintaining a healthy and thriving green roof. By providing adequate water to the plants, you promote their growth, sustainability, and overall beauty. Regular monitoring and adjustments will help ensure that your irrigation system operates optimally and supports the long-term success of your green roof. In summary, a green roof offers numerous environmental, energy-saving, and health benefits. Integrating a green roof into your house design is a sustainable and responsible choice that can positively impact both the environment and the occupants’ well-being.

Soil Mix
Low nutrients and lightweight substrates are a good combination for a green roof and its vegetation. The types of plants that you will have will depend on the type of green roof you are installing. There are three basic types of green roofing systems to consider when designing your project. It’s important to understand the slope of the roof and what structure and the future use or lifespan you’re considering as you make this choice.

We mention the above considerations as an impetus to diligent design and engineering, but do not purport to have specific knowledge of engineering principles. Such expertise and accompanying liability is the domain of qualified engineers. We will continue to pioneer new research to continue to provide improved support services to engineering professionals. For now we offer these considerations to stimulate a diligent review of design and engineering considerations as they pertain to green roofs.
Different types of green roofs
Ideal plants to survive summer heat are those that can handle climate extremes and pests. Those include many regional natives, herbaceous perennials, ground covers, succulents, sedums, herbs, and some edibles. Use only plants in these groups that are low-maintenance, shallow-rooted, and drought-resistant. When it comes to blending in with the landscape, few buildings are a greater success than Historial de la Vendée by PLAN01 Architects. PLAN01 has created a geometric, softly-pitched structure lined with a lush green roof. From a distance, this green roof looks nearly indistinguishable from the land around it, just a collection of hills in a field in France.
A Complete Guide to Understanding and Installing Green Roofs
Be sure to create a roof that will accommodate the width and length of the trays without leaving gaps. The trays can be planted with the same plants as a roof without containers or purchased pre-grown commercially by a nursery. However, it’s important to acknowledge the challenges involved in their installation and maintenance, including structural and financial considerations, and the technical expertise required for successful implementation. In this exploration of green roofs, we’ve uncovered their multifaceted nature and the myriad benefits they offer. Consulting with a professional is recommended to ensure proper installation and compliance with local building codes.
Components of a green roof system
Traditional sod roofs are an option in more temperate climates, such as the San Francisco Bay Area. The structure was a folly-like take on the Norwegian-style timbered architecture of the client’s house. They wanted a wild and unkempt look, like the turfed roofs of European houses. The wildness is enhanced by windborne seeds and those dropped by birds using the living roof as a suburban habitat. Very tall buildings, for example over 20 stories tall, are subject to virtually constant wind. This in itself is not a problem as it can easily be offset with irrigation, and we would consider a built-in irrigation system mandatory on any tall building regardless of climate.
Green Roof Technology is crafting Green Roofs from scratch for over 40 years because every roof is different. Especially, in regards of performance, installing costs, maintenance and efficiency a tailored solution is unmatched. Also installed directly on the roof and ideally from wall-to-wall for the best protection of the roofing.

If you opt for the DIY approach, ensure you follow the guidelines and get your roof and calculations assessed by a roofing contractor before beginning. ‘We also recommend that you seek out a reputable contractor to help install the waterproofing layer as any failings at this stage will prove disastrous,’ he adds. A roof installed by a professional will also be guaranteed, though the duration of this will depend on a bi-annual or quarterly maintenance visits (depending on the type),’ says James Beattie. A filter sheet goes above the drainage layer, which prevents soil from washing out and keeps the reservoir clear of debris.
Water Retention
Bare patches can be caused by weed encroachment, nesting, birds, or physical damage. To test for Wind Flow, a high powered wind turbine evaluates the ability of a modular vegetated system to resist sustained high speed winds. This test method is used to determine the level of sliding, overturning or scouring of the green roof. During an October 2015 testing of LiveRoof system, the assembly sustained winds until the turbine maxed out during the 210 km/h cycle. The rating is issued based upon a 1.5 experimental factor, thus the system tested has a flow resistance rating of 83 mph (133 km/h) under this standard.
‘Make sure gutters are kept free with nothing trailing into them,’ adds John. Spring and autumn are the optimum times to install green roofs for the roots to establish well so, if possible, organise the project to coincide with one of these seasons. The 1-by-2-foot black polypropylene trays—planted four months earlier and nurtured at a nursery—arrive by truck 95 percent covered with vegetation.
Before you do anything else, you'll need to assess the suitability of your roof to support a garden. It is no coincidence that one of TheCoolist’s favorite works of architecture features a green roof as its crown. The Paraty House by Marcio Kogan Architects is a sprawling tropical retreat, fully immersed in the vibrant nature of island life. Once its occupants arrive by boat, taking frequent trips back for groceries isn’t on the menu. Instead, its inhabitants tend to a large, well-stocked vegetable garden over its top floor. This green roof provides the herbs and veggies needed to compliment the freshly caught seafood just steps away from Paraty House’s magnificent deck.
A green roof will always be more expensive to install than a traditional flat roof because the underlying structure will likely need strengthening to handle the extra load (from the soil, vegetation, and other components). The garden is regularly studied to see how it affects urban areas for rainwater runoff, which types of plant species are best for Chicago’s climate, and more. The rooftop is not normally accessible to the public, but it can be viewed from any neighboring buildings.
In Germany, Hamburg leads the way with at least 70 percent of new buildings and roofs awaiting renovation to be green in the future. The California Academy of Sciences by Renzo Piano is a stunning achievement in green roof design. Such structures are no stranger to Italian architect Renzo Piano, who designed a long time favorite of TheCoolist, the Vulcano Buono in Nola, Italy.
Contact your local LiveRoof representative for referrals to qualified contractors in your region. It’s been estimated that a 1m2 green roof can take up to 5kg of emissions each year, which is the same amount as a regular car will emit during an 80km drive,’ says Tom Mckinna, designer at Resi. So, it concludes that 10 square feet can take up to 11 pounds of emissions.
You need to make sure that the structure can cope with the extra weight of your green roof, especially when saturated with water. Depending on the weight, additional structural support may need to be provided. Green roofs in themselves act as a layer of insulation, improving the thermal performance of your roof and saving you money on energy bills.
