Stormwater Characteristics of Greenroof Trays and Bags: An analysis of stormwater runoff characteristics in Greenroofs

Product Information

The Green Roof Company supplies premium quality sedum trays, pre-grown sedum matting and living roof garden kits, throughout the UK. Green roof technology can help reduce urban heat islands and conserve energy. Green roofs have been shown to keep rooftops cooler than conventional roofs. They also have a cooling effect on a city’s surface temperatures. A study in the Baltimore-Washington metropolitan area showed that green roofs could cool the surface by nearly 2°F (1°C)! The project studied green roofs that covered at least 30% of the roof surface. Sometimes excess rainwater can retain on the roof and weaken the underlying structure. On other occasions, it can overwhelm the sewage system and cause flooding. A green roof can save you from both.

GreenGrid Roofs

Get a structural engineer to tell you what your existing roof needs to support the weight of a green roof. You might have to add more joists, strengthen existing ones, or add bracing.” This style of roof gets its name because it has living plants growing on top of a house. Here are the cost factors related to soil and plantings on a green roof. Green Roof Tray System Cost For standing seam roofs, such as Kalzip, clamps are available that clip over the ridges of the standing seam and are fastened with a screw at the side. A variety of sizes are available to suit all different types of seam. The solar PV modules can then be bolted directly to these clamps. Whilst sedums are relatively hardy, low maintenance plants, sedum roofs do require a little due care and attention. Pitched against some high-quality roofing products, our M-Tray® modular green roof system beat off all competition to secure the coveted title of Best Roofing System or Product in the 2020 Build It awards.

Solar PV on Standing Seam Roofs (Kalzip)

Green roofs can reduce as much as 5 C of temperature in a city. This is because plants absorb more sunlight than they reflect. Therefore, the environment of a town with no roof garden will always be comparatively cooler than a city with no roof garden. If the roof was solid enough to add sedum onto it – potentially adding 100s of kilograms of weight onto the roof – it’s almost certainly safe to walk on. Intensive green roofs, in contrast, are much deeper, often exceeding 200 mm, and can accommodate a wider range of plant species, even shrubs and small trees. These roofs demand more intensive maintenance, including regular watering and fertilization, but offer greater aesthetic and recreational potential.

Modular roof trays are the best option for creating a roof garden. But to fully appreciate it, you have to first understand the general design types of rooftop gardens. You will then see for yourself why rooftop planter trays are so important. Our M-Trays® have been grown at our farm for several months prior to delivery. They will arrive with a minimum 90% cover. Does the area have to be level? Green roofs can also reduce energy use across different climates. The amount of cooling by the green roof depends on what type of material is used for the roof. Green roofs are typically covered with a growing media that contains soil but is different from the soil on the ground. It is specially-made mixtures of soil and inorganic materials like crushed clay and perlite. This keeps the material lightweight and provides good water drainage. Extensive green roofs are relatively shallow, typically 80 to 200 mm deep, and are designed for minimal maintenance. They feature hardy, drought-tolerant plants like sedums, needing little irrigation or fertilization. Solar plant screens can be used to hide building plant on the roof. Plant screens can incorporate solar into their design and fit the needs of the roof .Many cities around the world experience temperatures up to 10°F (5.6°C) warmer than the surrounding countryside. These areas are called “urban heat islands.” Their air surface temperatures are elevated more than usual. And, drought conditions are more pronounced than in nearby rural areas. When the roofs are this hot, it’s harder to cool the interior spaces of buildings. That means higher peak electricity demands, which can overburden city power grids. The level of air pollution in a city can also be intensified by the urban heat island effect. For example, higher temperatures in cities can increase levels of ground-level ozone. Ozone is a pollutant that causes respiratory problems.
