There was a gang of 6-8 men today putting up the roof tiles. Even through the showers they persisted with the work. That's what I like to see. They got a lot done in one day. They need to come back and grout under the corner tiles. I think they still need to finish off the lead flashings too.
I've seen the roofing down on another site, they use a conveyor which is loaded from the ground and is collected on top of the roof and stacked.
