Well, had a second guy come round to have a look and he was a lot less dramatic about it, that's for sure.
He advised, as the other guy did, that the purlin was surprisingly thin (2 inches) for the roof. He's suggested the following;
Make new holes in the walls either end, remove some slates from the roof and push the new (beefier) purlin in that way.
He'll leave the old purlin in, but move the rafters across to the new one.
He's putting together a quote now but reckons between £200-£300.
