ive had it happen to me
i was working for the council (as a carpenter) and we had a call out on a council run OAP home about a roof leak
well we arrived and it was 2nd floor, so gets the BIG ladder off the van, hoist them up, i run up to check it out, its on a flat roof and the lead work has cracked, so i shout down to get some " roof sealant paint " (its a fibre based waterproof paint, drys like fibreglass EVEN under water, incase your interestd
) we havent got any on the van, my mate says "stay there i will pop up the yard and pick some up"
he goes, phone me on the mobile says "we have had another call" a smashed window on some old dears house, so i will go and do it
i say "go on then, but be quick"
crash, ladders blow over and im stuck up on this roof
i phone my mate, he will be with me ASAP
1 & 1.2 hours go by and he arrives
i was freezing cold by that time
