Which types of rafters are used to frame a hip roof on a rectangular building?

The correct types of rafters used to frame a hip roof on a rectangular building are indeed the common, hip, and hip jack rafters.

Common rafters are the primary structural members that extend from the ridge or peak of the roof to the plate or wall beneath. They provide the main support for the roofing material and help define the roof's slope.

Hip rafters are the diagonal rafters that run from the corners of the building to the ridge, helping to create the sloped edges of a hip roof. This design allows for a more stable and aesthetically pleasing structure, as it provides a continuous slope around the entire perimeter.

Hip jack rafters, on the other hand, are shorter than common rafters and connect the hip rafters to the plate or wall. They fill in the space between the hip rafters and the common rafters, aiding in support and creating the roof's overall shape.

Therefore, this combination of rafters is essential for the proper structural integrity and design of a hip roof on a rectangular building, as they work together to create a roof that is both functional and visually appealing.
