As for structurally engineered roofing systems, there are two options: prefabricated roof truss and traditional stick-framed roofing. Trusses are manufactured at the manufacturer's facility and can be customized to fit any scope of the project. These are often stronger and more efficient than stick-framed roofs, as they use a system of interconnected members that tie the ceiling and roof together.

Designing this type of systemic roof always requires the expertise of an engineer to execute properly, as the trusses follow a tight rulebook of do's and don'ts. Due to the physics of the truss, engineers understand when and where renovations can occur – whether it is adding to the skylight or turning the attic into a scaffold. It’s not safe to make opinions when it comes to your roof trusses, since cutting the wrong framing member or modifying an unknown load-bearing wall can result in major structural issues.
When it comes to the skylight, it is a little easier because an engineer can accurately depict where the incisions can be placed without creating tension or damaging the trusses. However, renovating an attic space can be a lot more difficult and may involve a lot of remodeling as it all depends on what style of truss is installed.
Trusses have already left a lot of space for use, and still require permits, they will not be complex and overall construction costs will less. If the home has a closed roof truss, such as a king post, fan, or for example Howe, the entire truss construction will need to be redesigned to meet your design plans.
