Smitten, you are very smart to be here asking honest questions. Pre-planning and learning can save you a lot of problems later. Plus, the process is FUN.
Many houses are built with engineered trusses. This carry the weight of the roof and tie into the walls to create a unified structure. Cutting a truss compromises the structure and causes weakness in the building. Translation: bad thing.
Here is what a somewhat typical engineered truss looks like. What do you have in your attic? Take a pic and post it.
