How to build a hip roof without rafter or collar ties
I am building a 10×20′ 2×4 framed pool house with a 6/12 hip roof. I’d like to keep the ceiling underneath completely open, without rafters or collar ties. I understand that it is possible to do this, but I cannot find a description of how to do it. My understanding is that the common rafters will want to push the pool house walls out, and that there needs to be some accommodation to support that load.
Does anyone know how I can accomplish this?
