Sure did - I find it pretty hard on the toes, wet and the roof pitch pushing them into the front of my roof shoes. Also start getting cramp after that length of time. Really enjoyed a beer that night though!
It was painted metal - sure, they are a little slippery when they are new, this one was 3 years old and had started to oxidise a little so it wasnt too bad. Rubber soled shoes are a must have.
Cheers
