Scotland to Cornwall, we have been bringing new and old balconies to life with the addition of a grass roof installation using our range of artificial grass and underlays. In most installations, we would recommend the use of one of our underlays. This is to aid drainage especially over the winter months.
We have a selection of trims to finish external edges when required, ranging from stainless steel to powder coated, to match the roof garden environment to which it’s being installed.
Using artificial grass is a good alternative to decking, which can get slippery in the winter and requires regular time-consuming maintenance. Leaving concrete or slabs bare can look uninteresting and can be uncomfortable to sit on during summer evenings.
We specialise in commercial grass roof gardens from the smallest space to complete roof areas. The two projects shown here are both in Scotland; one being installed above a shopping centre in Inverness to provide a more aesthetically pleasing view to a new construction of residential properties, and the other was done at Aberdeen University during the upgrade of a number of buildings.
For the installation at Aberdeen University, the area to be covered was a raised roof space that had covered walkways; the current roof looked untidy and showed its age. To resolve this, the waterproof layer on the roof was replaced before we started. The first part of our installation was to install a cuspated drainage layer, which would ensure free flow of rainwater in every direction, and allow the natural falls of the roof take rainwater away.
The grass was installed over two days and sand filled to ensure it was protected against wind lift, which has to be considered on any roof area with exposed edges on building perimeters.
For this project at Heathrow Airport, the design brief was to install a putting green complete with contours and rough fringe areas. We used our professional putting surface Nylon Pro for the main putting surface with Wonder 36 as the surround.
Before we could install the putting green, a raised deck was installed to provide a level surface over the various pipes and roof elements to allow us to install the hole cups which needed a 150mm drop below the surface.
As with many large grass roof projects, the materials were lifted up by crane using our speciality lifting equipment that is designed to lift rolls without using slings which can cause damage during the lift.
Transforming your roof space into a safe green roof garden can provide you with a private area in an urban jungle. It creates a relaxing atmosphere so you can spend your evenings and weekends with friends and family simply enjoying the space and the views.
Grass roof space in work environments can also be developed to provide a calm area for staff breaks and summer meetings. The area could also be used as a smoking area (due to the new smoking regulations in the United Kingdom) as our sand filled range of LazyLawn artificial grasses conform to British Standards.
Evergreens supply many surfaces suited for covering roof garden areas in a variety of colours and textures. Why not consider our Funky range of coloured artificial grass to create a fresh contemporary look to your terrace?
Over the past 3 decades we have been trading, we established methods to install artificial lawns to roof garden areas without the need to fix to the current roof surfaces. This enables the building owner or tenant to have artificial grass installed without voiding any warranty on PVC or EPDM flat roofing systems. Our fixing method is also suitable on lead roofs or buildings with large lead flashings – this is of benefit, as using adhesives on lead will cause damage or staining when removing the artificial grass later.
When installing any roof area you must consider a few things before installing:
Is the roof water tight and will it remain so during the artificial grasses life time?
Will the roof structure carry the extra weight of the artificial turf allowing for snow, water and people using the area?
It is also very important to check the area for suitable safety barriers around the perimeter of the roof so there are no hazards for young children.
Another major element of any roof garden area is the increased wind speed, this can be overcome by a number of methods:
Use a sand filled artificial grass with a higher fill rate on the perimeter edges. (Roof must be checked for suitability of the extra weight).
Apply adhesive around the perimeter edge and ensure a good bond. (Check roof surface before use).
