I doubt it.
I use two pieces of 2 inch thick pink insulation foam cut 2 x 4 foot to spread the load when on my Passport roof. The two pieces are placed end to end and I swap them to move around the roof. They do not slip and they are easy on the knees while working.
BTW: I weigh about 200 lbs and do not notice much roof deflection.
