Does not raise the temperature of the building

On the Roof
If you live on the top floor of an urban oasis or have a home with a flat roof, you can easily have a qualified contractor install artificial turf over regular roofing materials. This approach gives you a small area for recreation and privacy if you so choose. The benefits of installing artificial turf on your roof include:

Does not raise the temperature of the building
Manufactured grass is not damaged by hail, rain, snow or ice
Allows you to create a small oasis where you can relax and enjoy the sunshine
Enables you to use the extra space in a constructive fashion
Improves the street appeal and value of your property
Helps to insulate the building for a more energy friendly space
When installing artificial turf on a flat roof, the use of PDS tiles is recommended to prevent damage due to excessive amounts of water building up underneath the turf. These tiles create a drainage channel between the roof and turf allowing water to run off and drain away, preventing it from standing in areas for any length of time. Your roofing contractor can advise you on the best and most cost-effective way to include beautiful artificial grass to your roof that will last for many years and through every season.
