Roof Deck Rail System

[Jason Gerasia]

Can anyone provide insight into a good rail system for a roof area that is going to be tenant friendly? I had a wood deck on a flat rubber roof that needed to be removed to replace the roof. Unfortunately, the cost of replacing the roof and installing a new wood deck (would require expensive permits, a lift for materials, material + labor cost) was going to be too much so I found another solution.  Very thick, sturdy "pads" I can put down on the roof, which would be strong enough to endure any small parties my tenants might throw on this roof-deck area.  See a link for the pads I'm considering below.  I've also attached a picture of the roof and where I would need the rail system.  I need to make sure it is sturdy and secure enough to support a person leaning against it so I don't have to worry (too much) about someone falling off the roof.

I'm hoping the rail system does not need to be fastened or screwed into the roof as to avoid any damage to the roof, which would create a potential for water leaks.  I needed to replace the roof due to leaks, so I am hoping this latest roof last me 20 years or so.  Any help is appreciated.  Thank you
