There are two basic ways to frame a roof. The first is commonly called "stick framing," or sometimes "handstacking" or "cut-and-stack." This type of roof incorporates framing such as rafters, ridges, and ceiling joists. See "Framing".
The other method is to use prefabricated, engineered roof trusses. Chief Architect allows you to design and display a wide variety of trusses.
Chief Architect does not engineer trusses. The trusses displayed by Chief Architect are for illustrative purposes only. They can show how trusses are used in your plan, and help you communicate to the licensed engineer who produces your final truss design where you want your trusses and how you would like them to work.
