An extensive green roof or Sedum roof is a roof with vegetation that is more or less self-perpetuating and that can be further developed and maintained. Extensive green roofs are a popular choice for homeowners, as they are lightweight and require very little maintenance, with no need for additional watering, unless there is a prolonged drought. They are suitable for both existing and new roof coverings. Extensive green roofs usually have an attractive low layer of vegetation, between 80 and 100 mm high, such as grass, moss, sedum or small flowers.
If you're using sedum blankets, you'll need an additional growing medium, but it can be quite shallow. Green sedum roofs are the most common type because of the plant's strength and low maintenance requirements. Green Building Magazine is a quarterly magazine that deals with the greening of buildings, from homes to offices. It focuses on energy independence and a healthy environment. Building for a Future has been published for 15 years.
The subscription costs only 20€. The second edition of the Green Building Bible offers more than forty reports focused on how to make your home or office greener and healthier. For just 9.94€, GreenPro is an extensive searchable database of green building products. GreenPro is absolutely unmatched in terms of speed and information delivery.
unique. More than 1000 products are listed available in the UK. Greenpro is an “ad-free” environment). Needless to say, we shouldn't create large roof water retention systems without protecting the roof from them, which is where the waterproofing membrane comes into play.
This tough material is the most important layer of any green roof. A dripping green roof (no matter how beautiful it is) is a failed green roof. Waterproofing membranes come in many different formats and installation methods. They can be burned or scrubbed with a hot mop, fluid applied or placed on pre-formed sheets.
Redundancy and resilience are key attributes when evaluating waterproofing membranes. As with water, you don't want roots burrowing into your roof. Not only does this mean that the roots have punctured the waterproofing membrane, which has impeded its effect, but that the roots themselves can cause serious structural damage. The primary purpose of the drainage layer is to move excess water to a drain or scupper and, ultimately, to bring it to the roof.
There is a delicate balance between over-draining and underdraining. All of them play a role in determining the best drainage layer for a particular project. During a rain event, the first few hours are always the most exhausting for stormwater infrastructure. The objective, therefore, is to delay roof runoff for as long as possible.
On a green roof, you are already going through the plants, the substrate and the drainage layer. If you add a water retention layer, it will take even longer. Frame the sides of the roof with mesh, wood or other edges that allow drainage to keep the soil in place. A modular sedum roof may be an option if you need to reduce weight (there are a lot of companies out there, so I'm not going to post any links).
By no means are all Sedum varieties suitable for use on extensive green covers or in a Sedum plant mantle. These include many natives of the region, herbaceous perennials, groundcovers, succulents, sedums, herbs, and some edibles. Green roofs are sometimes referred to as living roofs, grass roofs, or sedum roofs, but they all relate to the same thing. You can also easily and affordably purchase pre-grown sedum mats, ready to install, that provide instant, low-growing, low-growing, low-rise vegetation for roofs of any size.
Sedum roof trays are perfect for limited-access areas, they are lightweight and easy to drive for one person. This sturdy plant makes a Sedum roof more durable than a grass roof, as it can survive long droughts and extreme weather conditions and there is no need to cut it. Unlike the traditional Sedum roof, this green roof system includes a roll of substrate made of mineral wool instead of landscape roof substrate. Sempergreen Sedum roofs make a functional contribution to biodiversity by providing a safe nesting place for birds and nectar plants for insects.
