Raising the Roof
One of our current projects is a whole home makeover. Not only are we taking this down to the bones and renovating the entire thing, but we are removing the trusses in a large portion of the house and replacing that space with a vaulted ceiling. Because all of the bearing heights have been raised, we are going to frame the new roof with the old one in place and then cut out the old one after the fact. This does two things. It keeps the house relatively under roof during the bulk of the roof framing. It also gives us a much safer (and more efficient) platform from which to work, allowing us to walk around on the old roof, rather than using a crane or working off of ladders. Here is a picture that reveals the process, and another of the completed structure.
