We would like to install on a EPDM Rubber roof. What is the best way to install?

The most important issues of a rooftop are drainage and ensuring the original rooftop surface is not penetrated. Most installations over a TPO overlay have a drain membrane installed between the turf and the roof surface. This ensures that the water drains properly to roof surface drains. Depending upon the layout and roof makeup, a nailer board is typically fastened around the perimeter and the turf edges are secured to that. It is weighted down using infill just as a typical landscape install would be to hold down.
