What is used to provide vertical support from the wall to the ridge board during roof framing?

The correct answer indicates the use of temporary ridge support, which is essential during the construction of a roof. In roof framing, temporary ridge support is used to hold the ridge board in place until the roofing structure is secured and the entire roof system is complete. This support allows the framer to ensure that the ridge board remains level and properly aligned as the rafters are attached.

It's important to maintain a stable structure during this phase, which is why temporary supports are crucial. They provide the necessary vertical support and help distribute the weight of the rafters while the roof is being framed.

In contrast, permanent bracing typically involves structures that will remain in place as part of the finished roof system and do not serve the temporary function of holding the ridge during construction. Diagonal struts serve a different purpose, often used to provide lateral support and resist lateral loads, rather than vertical support from the wall to the ridge board. Cross beams, while useful for supporting structures, are not specifically designed for this stage of roof construction, as they tend to span across areas for structural integrity rather than providing vertical support to a ridge board.
