What is a common type of roof framing used in residential buildings?

Wood truss systems are a common type of roof framing used in residential buildings due to their efficient design and practicality. These systems consist of triangular structures made from wood that provide support for the roof and distribute loads effectively. The use of trusses allows for larger open spaces within a structure and reduces the need for interior load-bearing walls, which is particularly beneficial in residential designs where open floor plans are favored.

Wood truss systems are also lightweight, relatively easy to construct, and can be prefabricated, which simplifies the building process and often results in cost savings. Their design adaptability means they can accommodate various roof styles and configurations, making them versatile for a wide range of building needs.

In contrast, while metal frames, concrete slabs, and steel beams are commonly used in construction, they are less prevalent in typical residential roof framing. Metal frames may be used in specific architectural styles or designs, concrete slabs are more associated with flooring, and steel beams are generally utilized for structural support in larger commercial or industrial buildings rather than in standard residential applications.
