Not familiar with the product you reference, but I do know that for an extra 
fee, they can make membrane roofs walkable. I think it is a matter of 
putting a hard layer over any foam insulation (if yours includes that), and 
using a different membrane where foot traffic is expected. Another 
alternative is to lay out some of those thick open-cell mats like used in 
restaraunt kitchens. That will reduce the abrasion from boots and such. Look 
for the ones with the bumps on the bottom, to let water flow under them.
