When designing your roof garden, it’s worth considering how it will improve the building. A roof can transform what is usually a lackluster aspect of a building. It will create a green space which your family or staff can enjoy. Green roofs are more common in urban workplaces, although some homes are equipped for them. For us, the best aspect of green roofs is that they revive the pre-existing natural landscape.
They even act as micro-habitats for birds, insects, and other garden-dwelling mammals. However, it’s unlikely you’ll find a hedgehog on top of a high rise. Today we look at what makes a green roof garden and how to tell the different styles apart. With Garden Club London, you can have the roof garden of your dreams, one stylish, functional, and green all at once.
Why Green Roofs Matter
There are two green roof types we specialize in. Firstly, there are intensive green roofs, which take a traditional garden approach. Like a ground floor garden, homeowners or businesses use them regularly and recreational. They have all the same features as a regular garden, but on the roof. Then, we have what we know as extensive green roofs. The great thing about these is that they employ low-maintenance greening systems to collect rainwater.
These systems also store water, which could otherwise be lost as run-off. Due to the ever-increasing loss of natural spaces in urban areas, fewer places allow rainwater to soak back into the soil. The result of this is that water drainage systems must cope with far more water run-off. When storms occur, then, our drains may struggle to handle this excess, which can lead to flooding.
What Green Roofs Can Do for You
Aside from improving air quality, green roofs also look great, improving the appearance of homes and workplaces. Also, many people are unwire green roofs can store up to seventy-five-percent of your summer rainfall. Not only had that, but up to forty-percent in the winter, the water retained feeding your plants until it eventually evaporates.
Many clients, following completion of their green roof projects, report an increase in sound and heat insulation. One of the more notable benefits is the green roof garden’s ability to reduce the heat island effect. This is where urban environments like cities become overheated in warm weather, but green roof gardens play an integral role in keeping cities cool.
How to Build a Green Roof Foundation
We build most green roof gardens on a specialized base. They usually feature some sort of waterproofing membrane alongside root barrier material. These two features help protect the roof and interior of the building from moisture. It’s important for roof gardens to utilize growing mediums and substrates, too, which can be layered into the foundation.
When combined with stabilizing sheets and sandwiched together, this creates an ideal platform for your green roof garden. However, it is more cost-effective to utilize pre-cultivated mats and blankets for new layers. You can lay these out on paved roof areas like grass turf. They will even gradually form vegetation of their own, such as sedum, which is particularly durable against the elements.
