Lol sure why not I'll even do it for free
I once had a cancellation on a townhouse he wanted it all done trad and wanted the very top floor (maybe 30 foot from ground) "rubbed" .. I said alright no problem its dangerous tho whoever you employ to do that be aware should he fall he could be seriously hurt , his words which I'll never forget we're "not my problem" I think sometimes they don't stop and think oh and maybe the worst one other customer wanted me to walk on a very small roof around 50 foot high slightly pitched literally a death trap to clean 2 roof windows I was stunned and said would you really want me or anyone to risk my life to that degree honestly some people !
