The two basic types of roof framing systems are __ lumber and steel frame shed and gable hip and valley stick-built and trussed

## Step 1<br />The question is asking for the two basic types of roof framing systems. Roof framing systems are the structural components that support the roof of a building. <br /><br />## Step 2<br />The options provided are: lumber and steel frame, shed and gable, hip and valley, and stick-built and trussed. <br /><br />## Step 3<br />Lumber and steel frame, shed and gable, hip and valley are types of roof designs or materials, not the types of roof framing systems. <br /><br />## Step 4<br />On the other hand, stick-built and trussed are the two basic types of roof framing systems. Stick-built framing is a traditional method where the roof is built on-site using dimensional lumber. Trussed framing, on the other hand, is a method where the roof is pre-fabricated in a factory and then transported to the site for assembly.
