As long as the lift is working to get your weights on the roof cradles are a doddle, as for dope access, I have slagged these guys for years but the inspection guys do create a lot of work for us but most are just glorified painters. If rope access is a route anyone is considering Then do your inspection tickets and you won`t go far wrong but you must be able to bore the thruppenny bits of anyone who will watch your crap videos, "we are not interested and you are all boring c()nts" ah feel better I got that out.
