Green roofs are basically any type plantings placed on top or rather on the roof of a building. The technology is not new at all; it is mostly common in Germany.
Rooftop gardens are easily used and placed on flat roofs, though if designed in the right way, they can be placed also on a low pitch roof.
The first step into building a roof top garden knows the size of your roof and plants available in your area which can fit your roof perfectly well. Draught tolerant plants for instance sedums and cactus –like plants fit a rooftop garden with few depths of inches. Choosing the ideal plants is very much important in order to come up with a beautifully made rooftop garden.
Finding a professional to do the job for you is equally important, one who is in a position to work on various roofing sytems, manufacturers and designers, soil mixes and much importantly, climate.an architect for instance will help you out, not necessarily in the whole building process but to confirm if the building is safe to build a rooftop garden on it, this is probably the first step to take before you design a rooftop
Using less weight as possible is one thing that you should never fail to do while constructing a rooftop, even if your roof can take extra weight.plastics, fiberglass or foam planting containers work best to avoid added weight since they are light enough to hold the plantings.
Incorporating windbreaks is one important thing that you should never forget to do, you should realize that your rooftop will be windier than a normal garden. Trellises or any other kind of lattice will work well for your rooftop garden, the aim is to disrupt the wind rather than completely stopping it, besides you don't want to stop windflow,your aim is to reduce it.
Your garden rooftop should be built in such a way that you create some way to help you get water to the top part of it. You should never forget that your rooftop garden will need watering daily or if not then frequently especially in the hot weather. There are some ways that will help you out in this; you can consider having a water storage system constructed or an automatic watering system fixed at the top of the roof.
Never forget to confirm with relevant authorities weather rooftop gardens are prohibited in your area. Check this out from local ordinances or the home owner association regulations body, instead of wasting money, labour and time on something that is against the law.
Rooftop gardens are not only beneficial to the environment but also a great investment for you since it reduces your heating and cooling bills each year. They are extremely beautiful and considerably give you an extra insulation during the winter season and a cooler environment during summer, a songbird habitat as well is one thing that can make each day of your life enjoyable .having one is definitely worth your efforts.
