Most of the trusses we need for the roof of this house are up. It's been a relatively quick process to hoist each truss up individually and secure it into place. With the three of us working on this, it takes about 30-40 minutes for every truss. There is however a small problem we have uncovered. Due to an unfortunate mistake in our calculations, we will be unable to finish the roof. The trusses we are missing will have to be manufactured and delivered at a later time.
