2014 Fleetwood Jamboree roof question

[Lonallie]

I’ve only had this 2014 for two months now. Was wondering what the roof made from Rubber, Steel or fiberglass. The resaon is I need to get up there and do some inspections and cleaning…I’m a big boy 6’4” 320 and don’t want to cause any damage do to my size…suggestions? When i changed out one of the vents the roof looked to be 6" or more thick..

Well we don't have a ladder attached so it's another problem...if one was attached I would have thought walking up there was ok but ....don't have one, reason why I asked about load limits
