Coming from a complete novice, so forgive me for my question, but we are considering extending our house up, and I was wondering would we be able to use the same roofing trusses and tiles again? The extension will be a carbon copy of the ground floor, maybe slightly more narrow than what it is now (same length), the ceramic tiles are in excellent condition, so really, I am wondering can this be done (albeit wtih a few modifications to the trusses)? Would we be saving money by doing this?
Thank you,
