Hip jacks are typically used on hipped roofs, which have four sloping sides that meet at a point. They provide additional support and stability to the roof structure, especially in areas where there is a change in pitch or angle. Consulting with a professional roofer can help ensure that you choose appropriate materials for your specific needs while also ensuring structural integrity over time. When designing your roofing system, it’s important to consider factors such as rafter spacing and size based on local building codes and regulations. They offer more living space under your roof as compared with gable roofs since there is no vertical wall limiting headroom. One advantage of using hip roofs is their stability in high winds or hurricane-prone areas due to their aerodynamic shape. Hip rafters are typically longer than common rafters because they need to span a greater distance between two points. These rafters run diagonally from the corners of the building to the ridge and provide support for both the roof decking and any weight on top of it. In addition to their strength characteristics, common rafters can also be designed with decorative features like notches or curves that add visual interest to a home’s exterior. Longer spans require larger cross-sections to prevent sagging or bending under heavy loads like snow or wind. One important consideration when using common rafters is their length. They run from the ridge board at the peak of a roof down to its eaves, providing support for other structural elements such as purlins, collar ties, and ceiling joists.Ĭommon rafters are typically spaced 16-24 inches apart depending on local building codes and snow load requirements. Common rafters are the most basic type of roof rafter and form the backbone of many roofing systems.
